Misprint in F4/G4 Programming Manual (Bitband)

There is a misprint in your PM0214 Programming manual "The Cortex M4 processor" in the chapter chapter 2.2.5 "Bit-Banding", above figure 9. Bit-Banding is nicely described there, but of course all bit addresses have to end by "00"... Your first exam...

RTC power supply and voltage amplitude

For STM32F4 series, when PC14/PC is used for external crystal(32.768k), which power supply is output for crystal? What is the voltage amplitude？

大家好，我最近在keil上使用STM32G0B1RE的芯片时，�?�现仿真时通过system viewer看�?到ADC的寄存器（�?示例图）（�?�有部分寄存器能看到，例如GPIO，IIC等），硬件用的是G0B1RE的NUCLEO�?�，请问有�?碰到过类似问题，还请帮忙解决一下，谢谢

I2C Transfer with DMA completed but DMA interrupt routine is not work

I work on basic i2c example with DMA using HAL library. When i observed data in the debug section that data read correctly but DMA did not rise flag TCIF(transfer complete flag). What might be reason ?void DMA1_Channel1_IRQHandler(void) { if(__HAL_D...

powerstep01

In powerstep01, voltage mode is more preferable for lower speed while current mode is more suitable for higher speed. Do anyone know what is the reason ?

Hi I am working on stm32f051c8tx in adc part , below is the code I am using, the issue is, there is a variation of 30 millivolt from the multimeter to the voltage read by the controller.

static void MX_ADC_Init(void){ /* USER CODE BEGIN ADC_Init 0 */ /* USER CODE END ADC_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC_Init 1 */ /* USER CODE END ADC_Init 1 */ /** Configure the global features of the ADC (Clock, ...

Nucleo-G031K8 Program Will Not Start With 12v on VIN Pin LD1 Flashing Slowly

Hi there,I have a Nucleo-G031K8 evaluation board and am unable to get the program to start when connected to an external power supply. I have a bench top power supply connected to the VIN pin with 12v+ The LD2 led is light indicating power is workin...
