PSoC 4 Architecture

I want to use the WDT interrupt in wdt counter 0 and WDT reset in wdt counter 1 but after initialize, it will go to infinite loop can't reset.

If I just enable EDT interrupt in wdt counter 0, it will no problem.  Below is my config code of the watchdog timer

    CySysWdtDisable(CY_SYS_WDT_COUNTER0_MASK);
    while (CySysWdtReadEnabledStatus(0));

    CySysWdtWriteMode(CY_SYS_WDT_COUNTER0,CY_SYS_WDT_MODE_INT);
    CySysWdtWriteMatch(CY_SYS_WDT_COUNTER0,WDT_INTERVAL_1MS); // WDT interval  Timer = 1msec in counter 0
    CySysWdtWriteClearOnMatch(CY_SYS_WDT_COUNTER0, 1u);
    CySysWdtWriteCascade(CY_SYS_WDT_CASCADE_NONE);
    
    //Enable WDT counter 0 
    CySysWdtEnable(CY_SYS_WDT_COUNTER0_MASK);

    CySysWdtWriteMode(CY_SYS_WDT_COUNTER1,CY_SYS_WDT_MODE_INT);
    CySysWdtWriteMatch(CY_SYS_WDT_COUNTER1,WDT_1S); // WDT Timer = 1sec in counter 1
    CySysWdtWriteClearOnMatch(CY_SYS_WDT_COUNTER1, 1u);
    CySysWdtWriteCascade(CY_SYS_WDT_CASCADE_NONE);

    //Enable WDT counter 1 
    CySysWdtEnable(CY_SYS_WDT_COUNTER1_MASK);

    // Lock WDT registers

PSoC 4 Architecture

Hi everybody,

I would like to use two CSD modules in same project. But i took error message about Resource limit end of the building operation like attached. 4100M datasheet says : 

"Each CSD block has two IDACs which can be used for general
purposes if CapSense is not being used.(both IDACs are
available in that case) or if CapSense is used without water
tolerance (one IDAC is available). The PSoC 4100M has two
CSD blocks which can be used independently; one for
CapSense and the other for IDACs.
The two CapSense blocks are referred to as CSD0 and CSD1.
Capacitance sensing inputs on Ports 0, 1, 2, 3, 4, 6, and 7 are
sensed by CSD0. Capacitance sensing inputs on Port 5 are
sensed by CSD1."
 

Do you have any IDEA ? Also, i have another dramatic information : when i try to same operation with CY8C4127AZI-M485, it can work without any error. There is a table at page 30 of datasheet. The table gives some information about IDAC and CSD capabilities. But i can not comment table and above information at same time.

Thanks in advance for your valuable comments.

Hi:

    I want to use the PSoC4 EZI2C Slave block.

I also study the example "SCB_EzI2cCommSlave", but I can't find where i can get the sub-address from master.

In this demo project, it is said that the read base address is 0x03, but I can't find where it is set?

For example:

The master want to read data from sub-address"0x01"-"0x05", how can I set the slave?

Best regards

thanks a lot.

PSoC 4 Architecture

Hi All! 

I am using the CY8C4126AZI-M445 as MCU. I will control 31 capacitive sensors and I will drive to led display also. So, I have to optimize pin using.

For this reason, I plan to use HC595 ICs to drive display via SPI. But I won’t use MISO pin in our project and I don’t want to assign any pin for MISO of SPI. When I try don’t assign, after build operation, complier assign automatically. What can I do ? PSOC4 SCB Module(Ver 3.10) has not bidirectional option for SPI. Could you guide to me what can I do use SPI module with only 3 pins ( MOSI,SS,SCK) ? 

Thanks in advance

I2C lockup on power up

PSoC 4 Architecture

Just wanted to run a scenario by you that is causing me some grief. I have a brd with a cy8c4247lqi-bl453 talking to an accelerometer (MMA8451) through I2C. The circuit is powered from a coin cell (CR2032) and the cypress chip is the master. I am using P1.4 and P1.5 for I2C. If I program the chip from the miniprog the I2C will start as soon as the chip is done programming and will run fine as verified by my scope. As soon as I try to run the device from battery with the miniprog disconnected the I2C locks up, both SCLK and Data go high. The chip is running because I am toggling one of the cypress pins and it is cycling. For some reason the I2C is getting hung up under battery supply. BTW, I also replaced the battery with my bench supply and had the same issue so I don’t think it is a supply issue because the chip is running. Any ideas?

PSoC 4 Architecture

Dear all PSoC fans,

I am having a problem when connecting to a PSoC 4® chip that I am using in a project. Apparently the MiniProg 3® connects to the PSoC and reads something as shown on the picture attached. I have 5 boards using a PSoC4 (CY8C4245AXI-473) but only one of them had connected properly to the Miniprog and the PSoC Creator. All of the others ar showing the same issue where the Cypress ID is 0x00001193 but one that shows 0xBEEF1193. Sometimes the PSoC Creator detects a valid PSoC4 chip, but when I try to program it just say that the connection failed or was unable to erase the flash.

Have you guys know what is happening? Did I fry the PSoCs?

Nicolas

Hello all,

I recently got a new CY8CKIT-049-42XX. I wat to make a project that blinks an led for 30 seconds, then turns it off. My problem is that every other 30 seconds, the led is on for 30 seconds. So, to make this work, I added an if statement with if (led_Read == 0), but that generates an error. How would I solve this?

 

Thanks,

USBUART showing as Unknown USB Device

Forums: 
PSoC 4 Architecture

I'm using a PSOC CY8C4248AZI-L485 and trying to implement the USBUART but no matter what I do, I can't get it to recognize the device in Windows.

I started with the sample USBUART project, and made very few changes beyond stripping out some #ifdef code that wasn't executing, and adding a red and green status LED.  

The 4248 is running at 3.3V, and I'm self-powering it from an external source.  The 5V from the USB is applied to the VBUS, and I've tried all combinations of VBUS monitoring both on and off.  I've tried swapping D+/D- and it made no difference.  The D lines were initially passed through series resistors, but I've since eliminated them.  There is no other filtering or static protection on the current prototype.

Whenever I plug it in, I get an error message in Windows (10) that the Device Descriptor Request Failed.  It usually recognizes that I did plug something in to the USB port, but I will add that especially early on during the dev cycle, it wouldn't always attempt to load drivers.  Somewhere along the way it's gotten more responsive to that function.

I installed the .inf file that is generated as part of the projct (I had to boot into the recovery mode to allow Windows to install an unsigned driver).  That made no difference.

I had also installed some generic Cypress USB driver that I found during my travels, but that hasn't seemed to make any difference either.

Attached is the project as it stands today, as well as a screenshot of the error message that I'm seeing in Device Manager.  

I'm new to the USB device development, so I'm not really sure what else might be useful to others to troubleshoot.  It seems like I'm just one little step away from getting this going though.

PSoC 4 Architecture

I am completely new to this platform. I have a PSoC 4200 BLE CY8C4247LQ. I am not sure this is the right forum.

I need to read an analog pin to get the voltage read by a sensor I conected. It is an IR sensor (TCST 2103), I want to get the voltage the sensor is reading but I haven't found an easy way to do it. I don't know how to use the SAR ADC  since in my PSoC Creator there is just a "Sequencing SAR ADC" with multiple inputs I don't understand.

Can you please give me some ideas about how to connect it and how to read after that? I thought it would be as easy as a digital pin. Or if I need an external circuit to modify the signal before reading it.

hi all,

i am trying to send command of UART (using docklight)for bootloading psoc4200.except program row command all other command is working properly.for program row command 0x03 error is coming.i tried different way to send this command but same problem is comming.

i want to load my project file through this command on docklight.

following is sequence:-

>>  01 38 00 00 C7 FF 17    ->Enter bootloader command (0x38) 

 << 01 00 08 00 93 11 C8 04 11 28 01 01 4c FE 17  -.response.

>>01 32 01 00 00 CC FF 17     ->Get flash size.(0x32)

<< 01 00 04 00 34 00 FF 00 C8 FE 18   ->response (first row:-34 00,last row:-FF 00)

>>01 37 04 00 01 01 01 01 C0 FF 17   ->Send data (0x37)

<<01 00 00 00 FF FF 17                   <-Response.

>>01 39 04 00 00 34 00 01 8D FF 17      ->program row (0x39) (array id:-00 row:-34 00 data:-01) (i also send last block of send data command with approriate checksum also try different row.)

<<01 03 00 00 FC FF 17               ->error 0x03.

Bootloader setting:-

communication component:-UART 

wait for command time (ms): 0 (wait forever) (i also tried 2000)

checksum :- basic summation.

why i always get 0x03 error?

PSoC 4 Architecture

I have been working with the PCF8574 chip which is set up to work in a 4 bit mode where P0-P3 from the 8574 chip  are connected to D4-D7 of the LCD and P4-P6  are connected to E, R/W and RS. P7 is connected to the Back Plane. I have been trying to use the I2C_LCD component which has not worked since it appears that the data is being transferred in an 8 bit format rather than upper and lower 4 bit nibbles. Are there any software solutions? I am hoping someone can point me in the right direction.

My PC board Layout design would be significantly simpler and I would be able to keep it to a single sided board if I could find an I2C solution rather than having to use the CHAR_LCD component to interface with the LCD.

Measuring the internal reference voltage using ADC

PSoC 4 Architecture

Hy,

I am trying to read the battery voltage, but the reference voltage (VDDA) is not stable at all. Therefore, the output of the ADC varies a lot. I was thinking to use another resistive divider to be able to reference everything to 1.024V, but I have a lot of PCBs and I do not want to make this modification on each. Therefore, I am wondering if there is a solution to measure the reference voltage and then, from this, calculate the real VDDA.

I am using a PSOC 4xx7 BLE

 

Thank you in advance

I'm attempting to add a bootloader to a touch pad project, so I can make tuning settings to when its in the case. I've added a new bootloader project to that workspace, made the original project bootloadable, and pointed the dependencies of bootloadable to my bootloader. When I try to build these projects together I am getting a series of errors.

Bootloader Tutorial

Forums: 
PSoC 4 Architecture

I'm looking for help on understanding the bootloader and bootloadable components of the PSOC Creator. I've looked at the forums a lot and seen some of the tutorial videos, but I'm still confused on how exactly to implement this.
 

End Goal: Running a CPU with Android on it connected to a PSOC microcontroller and capsense touch pad via I2C. I want to be able to update the firmware of the touchpad controller with a custom driver using the CPU to do I2C writes to the bootloader.

To get an understanding I'm starting with a simple project using LEDs to indicate switches between the bootloader project to two bootloadable projects on the PSOC 4000 kit.

I used the Bootloader Example project provided by Cypress and the two bootloadable projects which will simply toggle the red or green LED depending on which one is called by the bootloader. I call the Bootloader_Start() function in my bootloader main.c and then I poll two buttons attached to gnd and an IO. When the button is pressed the I call Bootloader_Exit() with the application ID of one of the bootloadable projects. The project then should begin to run and exit when the button is released.

Things I think I got wrong:

1.) While debugging the bootloader after I call Bootloader_Start() the code doesn't continue to run into the polling part. How do I properly implement this, so that if none of the buttons were pressed I would theoretically be able load an updated firmware for one of the bootloadables? (Soon I'll get to the point of using the bootloader utils api to create the custom driver to do this, not there yet though)

2.) I've seen some mention in the forums that the PSOC 4000 kit board already goes into a bootloader program and what I'm doing here won't work unless I point the bootloadbles to the bootloader workspace that comes with the kit. Is there away to implement my own bootloader on the PSOC kit, so I can expand my understanding of how this works?
