RE: The Bio Highway – Exploring ADC with Cypress ModusToolbox and Device Configurator

The photo under element14 community seen currently out of order......so i don't know what wrong with your config.

Under Device Configurator you need config the ARef, Clock, GPIO and connect together under Peripherals>Programmable Analog>12-bit SAR ADC.

After that you need to call Cy_SAR_Init and Cy_SAR_Enable ..... which may sophisticate.

As for simple Analog Input, just use https://cypresssemiconductorco.github.io/psoc6hal/html/group__group__hal__adc.html ,

as the description said this is High level interface, so leave the Device Configurator default (no Analog port tick, SAR no tick, Aref no tick, all close).

following the instruction and just change the P10_0 to your analog input. The code should work.

If you study the code inside, the cy_hal_dac accuracy build, setup and init all of relative SAR,clock,ARef....., if you config those under Device Configurator, they will conflict and not work.

The Device Configurator give you more flexible but it harder to setup, as cy_hal_adc easy of use and most case it should work.
