Hi. I'm using Keil5.ADC encountered an error in my program(from function HAL_ADC_PollForConversion), so I tried debugging and found the following problems. As shown above, the register value in CFGR1 returns the address.In a typical program(Operating...

I'm writing firmware for stm32c011f4u6 using Keil5. I downloaded and checked an example about ADC from the homepage, but I only found the code that uses DMA. Is there any example of using ADC with Polling instead of DMA? Also, I need an example for m...

I'm using stm32c011f4u6 and keil5. and I'm using 2 ADC channels by Polling. Every time I read an ADC channel, it only return '0X01AF'. This is the same for both channels,even if I remove one channel and read it again with only one channel used, the s...

I am working on firmware with stm32c011f4u6 mcu. When the program is operated, a timeout error occurs after falling into the infinite loop of the function below. HAL_StatusTypeDef RTC_EnterInitMode(RTC_HandleTypeDef *hrtc) { uint32_t tickstart; H...

Hello, I am using STM32C011F4U6 MCU.As I mentioned, I wonder if it is possible to do Erase in units smaller than Page.The specification does not describe such a function, but is this function possible?

I checked more and found out that there was a problem like this. The value of the CFGR1 register is returned to the address location of the register.For reference, the value of the register is as follows in the regular program(operating normally).Th...

I'm using Keil5. Also, I wrote the program by adding settings directly from the template without any initial settings, and I think I missed something in the process.

When I checked, ADC_PollForConversion encountered an error. I marked the location of the error in red.However, what I wonder is that when I created a new file and compiled it using the same settings and code, it worked fine. i really don't know why.....

I've tried changing the settings, but no matter how I call ADC_Start twice with NumberOfConversion as 1, or call once with 2, only 0x01af is output. Why is this happening?

Here's my code. void sapp_hal_init(void) { uint32_t tmp_index; /* Initialize ADC group regular data buffer values */ for (tmp_index = 0; tmp_index < 3UL; tmp_index++) { uhADCxConvertedData[tmp_index] = (__LL_ADC_DIGITAL_SCALE(LL_ADC_RESO...
