what does the datasheet mean ?

what does the datasheet mean ? This is the STM32F103C8's datasheet.In Medium-density devices has 1xPWM timer and 3x16bit timers.​​i know that 16bit timer can be PWM function.What is the difference between 16bit timer and PWM timer?​​STM32F103C8 timer...

How to change DMA from 16bit to 8 bit transfers

I have inherited a wadge of working SPI DMA code for a product. I want to send bytes rather than 16 bit words. In order to change the length of the SPI packets from 16 clock cycles to 8, I changed the DMA_CCR1_MSIZE & PSIZE fields in DMA1_Channel3->...

Resolved! Problem with HAL_I2S_DMA_Receive()

I am using STM32f407VG Discovery for audio application. I am having a problem while using the I2S2 in Slave Receive mode using the HAL_I2S_DMA_Receive() for receiving 16-bit data on a 32-bit frame. I am able to get the Audio data correctly at times a...

STM32G070. In the code generated by the CubeMX, there is the colock source is selected for the TIM1/15, TIM1CLockSelection/TIM15CLockSelection. But in datasheet, the clock source is only TIMPCLK and no other source. I think this is the tool bug.

void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Configure the main internal regulator output voltage  */ HAL_PWREx_ControlVoltage...

Just how powerful are STM32s?

I'm sure this is a pretty loaded question, especially considering that there are a range of them out there now, plus I'm sure it also varies based on application(s), ​im just curious because I am coming from an Arduino world (and going to school to g...
