ChibiOS Free Embedded RTOS

Thanks, It works!

And what files need to change the DMA channels?

Good afternoon.
If I use in the project (built on ChibiOS v16.1.3) USART1 and I2C1 - USART1 not work. Please tell me where to fix it?
Thank you!

You're right, open circuit measurements. Thank you!

Yes,

const ADCConversionGroup adcgrpcfg1 = {
.circular = TRUE, // FALSE,
.num_channels = 1,
.end_cb = adccb, // NULL,
.error_cb = adcerrorcallback,
.cfgr1 = ADC_CFGR1_EXTSEL_SRC (3) | ADC_CFGR1_EXTEN_RISING | ADC_CFGR1_RES_12BIT | ADC_CFGR1_DISCEN,
.tr = ADC_TR (0, 0)
.smpr = ADC_SMPR_SMP ...

Good afternoon.
Connected to the input STM32F072C8 GPIOA1 source voltage and try to measure it with the ADC. To measure some nonsense, but not what I connect. But if I measure the same input voltage GPIOB1, all measured well. What could be the inlet GPIOA1?

I use the driver for STM32F407. He began to work only when I comment out the line:
// while (wdgp-> wdg-> SR! = 0)
//;

Everything is working. I have had
.circular = FALSE, and it is necessary
.circular = TRUE,
Thank you!

It does not work, even though it feels like you. Upon entering the interrupt handler (adcb) look at the contents of the register of CR and see what ADSTART bit = 0 (reset).

Can I use this mode of ADC with the following parameters:
#define ADC_GRP1_NUM_CHANNELS 1
#define ADC_GRP1_BUF_DEPTH 1
???
