Hi,

G0 examples are in the "multi" projects, no standalone projects for newer platforms (going to remove gradually old ones too).

trying to use ADCD1 on G071 device and getting this compile error, i'm using the example from the multi projects

Do have another question

Using a in a gptimer callback can you start the ADC conversion ?

i.e.

static void gpt3Callback( GPTDriver *gptp )
{
adcConvert(&ADCD1, &portab_adcgrpcfg1, samples, ADC_GRP_BUF_DEPTH);
cacheBufferInvalidate(samples, sizeof (samples) / sizeof (adcsample_t));
}

sorted it with

adcStartConversion and adcStartConversionI

Hi,

Correct, use adcStartConversionI() from callbacks and don't forget to enclose it in the proper lock/unlock (from ISR) functions.

When doing this kind of things make sure to enable the state checker in chconf.h, it catches all this kind of problems easily.
