Welcome! First question asked

Hi everyone,

I'am now stuck since two days with an issue being not able to use the hardware start of conversion of my ADC. I use a CY6C6137BZI chip. The ADC is set to single shot with hardware trigger. In order to get rid of this problem i created this top design :psoc.png

I look at SOC_TRIGGER and SDONE with my oscilloscope. I clearly see the incoming pulses at SOC_Trigger but no reaction of the ADC. As soon as i add any sofware driven triggers via ADC_1_Start_Convert() i get pulses on SDONE (Same with a free running ADC). When i have no SDONE puleses i get also no new analog values so its not a problem with the SDONE pulse. I alredy tried a lot of different ADC configurations with low and high sample rates and a lot more. Nothing seems to help. The ADC Version is 2.1 and I am using PSoC creator 4.2.

Can somebody help me here? If I had to guess I'd say this is a bug in the component. At least i have no idea what else i could try.

Thank You and best regards,

Christian

I made a demo to test the sdone and eos terminal output of PSoC6 SARADC component,  my test result is same as expect.

When i press the switch and release it once, two LEDS both toggle one time too.

My test project attached, you can run it on CY8CKIT-062-BLE DVK directly.
