Arduino for STM32

I think something is wrong with core.
Arduino Ide doesnt take build_opt.h into account.
so added flags manually.
ADC_CLOCK_DIV_4 is undefined
so i tried to give a value to it. So it throws another error.
AdcHandle.Init.ClockPrescaler = ADC_CLOCK_DIV; /* (A)synchronous clock mode, input ADC clock ...

#define ADC_SAMPLINGTIME ADC_SAMPLETIME_55CYCLES_5;
semicolon does the trick. Not sampling time worked. But i defined in SystemClock Config PeriphClkInit.AdcClockSelection = RCC_ADCPCLK2_DIV4
but I looked at the RCC register ADCPRE: ADC prescaler.. It it DIV2... should I define it with build_opt.h

Hi,

I searched forum, tried everything I read. I'm usingg STM32F103RCT based custom board. I want to read analog values for PC0 and PC1.
I have created hal_conf_extra.h file

#ifndef HAL_CONF_EXTRA_H_
#define HAL_CONF_EXTRA_H_
#define SERIAL_RX_BUFFER_SIZE 256
#define SERIAL_TX_BUFFER_SIZE 256 ...

I found. After enabling Timer2 Channel 3, Timer Dier Register should be updated with this bit
Bit 11 CC3DE: Capture/Compare 3 DMA request enable

Hi,

I try to implement XY2-100 galvo mirror scanner control protocol. I want to use dma for setting gpio pins. I

rcc_clk_enable(RCC_DMA1);
DMA1_BASE->CPAR1 = (uint32_t)&GPIOA->regs->ODR;
DMA1_BASE->CMAR1 = (uint32_t)pingBuffer;
DMA1_BASE->CNDTR1 = 10;
DMA1_BASE->CCR1 = (DMA_CCR_PL_HIGH | DMA_CCR ...
