Hello,I have an issue with the maximum speed of the ADC clock for Nucleo-C031C6. In the device datasheet, it states that the max clock speed is 35 MHz. However, in STM32 CubeIDE, I have the option to select the asynchronous clock mode, and DIV1 is ac...

Hello, I have an issue with the ADC conversion timing while using the DMA controller.I have only configured 1 ADC channel, 12b res. and the ADC clock is at 24MHz (50% of SYSCLK), and it shows correct conversion results (verified by a simple voltage d...

The problem is I can successfully transmit-receive up to 4 bytes of data. Above that amount, anomalies happen. I need to transfer 20 bytes of data in both directions. Does this have anything to do with RXFIFO and TXFIFO buffers being 4 bytes, or is i...

Thanks a lot for your feedback!One more question (just for clarity), why does CubeIDE allow DIV1 prescaler for ASYNC clock, but not for SYNC clock, while the system clock is at 48 MHz (I understand why it should not be allowed due to the ADC clock sp...

So if I understand correctly, the code:/* Benchmarking *//* Reset TIM6 counter */TIM6->CNT = 0;/* Start TIM6 counter */TIM6->CR1 |= TIM_CR1_CEN;/* ...CODE TO TIMESTAMP... *//* Benchmarking *//* Stop TIM6 counter */TIM6->CR1 &= ~TIM_CR1_CEN;/*Obtain t...

Thank you for the reply! That is why I did this 'while (SPI1->SR & SPI_SR_BSY) {};' inside my original code. However, I tried your version and anything above 4 bytes does not cause the slave to ever go into the HAL_SPI_TxRxCpltCallback() function. If...

Nucleo-C031C6 ADC maximum clock speed

ADC via DMA conversion time on Nucleo-C031C6

I have an issue with the HAL_DMA_TransmitReceive() function. I am using full-duplex SPI communication between STM32F030R8T6 as master, and Nucleo-C031C6 as slave. I am only using DMA on the master side. My DMA clock is at 40MHz, SPI clock is at 10MHz.
