Hello All!
I have a need to generate a PWM signal with an adjustable duty cycle controlled via a 10K POT. Having a bunch of 8 pin CY8C4014SXI-420 chips laying around I decided to try using them for this project. Just enough room for Analog Input and PWM Output.
I am attaching my project which 'should' work. Of course it doesn't....
I am using the CSD_ADC component and feeding it's output to the compare of the PWM component. I started from an example I think i found in the component docs. I have increased a couple of the delays to try getting it to work, but still a no go.
When debugging, I basically get only 1 value from the ADC (0x19FE) with it connected as shown. I get basically a 0x01 when the pin is disconnected from the resister. With my multimeter, I am reading about 1.2V at the pin when connected, no matter the POT setting. (Sweep arm of pot is verified working and voltage is changing when disconnected from PSoC...)
I have tried 3 different chips, so I don't think the issue is hardware.
Anyone have ideas?
