I can't get data from CAN

Hi everyone,I'm new using ST microcontrollers and I've began using blue pill development board. My project has to read data from CAN at 250 kb/s. Also I'm using MikroC PRO for ARM to create the program but I'm unable to read any data from CAN so far....

The STM32L476 seems stuck at the reset frequency of 4MHZ. How can I switch to use the HSE?

 I need to run off the HSE and I am not seeing any glaring errors in the STM32 cube generated code; however I am still at 4MHz. ------SNIP--------------------------void SystemClock_Config(void) {     RCC_OscInitTypeDef RCC_OscInitStruct;      RCC_Clk...

STM32L073/Unique device ID registers/unique ID bits [95:64]

I am confused by the naming "unique ID bits" which implies that these bits are really unique from device to device.Are these bits really unique from device to device, or are the other bits (WaferNr,LotNr [0:63]) also required to build a unique id?

I am having difficulty in getting a working clock configuration for an STM32H753 chip.

the STM32H753 chip is mounted on a board with an external 12Mhz HSE crystal and 32k LSE crystal. Using the CUBE config tool I have the attached SystemClock_Config function. The function gets stuck waiting for a valid RCC_FLAG_PLLRDY signal in line 42...

How to use HAL_SPI_Receive_DMA correctly?

Posted on June 18, 2018 at 15:00Hi,How to use HAL_SPI_Receive_DMA correctly? We need to receive an ongoing data stream via spi. For that we use spi receive with dma. But if we call HAL_SPI_Receive_DMA once before the main loop the HAL_SPI_RxCpltCall...

Timer DMA Burst mode (arbitrary waveform)

Posted on September 22, 2017 at 14:25Dear all,I'm having a problem creating a arbitrary waveform using timer 1, MCU STM32L476RG. I use STM32CubeMX (4.21.0) to generate all initialization code after which I try to start a DMA transfer from memory to ...

LWIP_HTTP_SERVER_Netcomm_RTOS program for STM32f207 microcontroller is not complied using MDK-Keil tools with limited code size . Is there any solution to compile this code?
