HAL_GetTick() always return 0 when i use UART

Hi, I work with STM32L562VET6Q, and when i try to comunicate with uart HAL_GetTick() fuction doesn't work because always return 0, but if i don't use uart work perfectly, What could it be due to? I try to change prioritys in NVIC interrput table but ...

STM32F4 + UART + DMA + IDLE detection + High Rates + Variable Length Messages = CHAOS!

Hi!I have an INS that sends the following frames: Frame 1 of 60 bytes every 40 ms Frame 2 of 70 bytes every 20 ms Frame 3 of 32 bytes every 1s Frame 4 (unwanted, but impossible to deactivate) of almost 500 bytes every 2s. I am implementing receive wi...

Can STM32F105 do 13-bit SPI with 13 clocks?

I need to interface with a Viniculum II from FTDI. It requires 13 bits over exactly 13 clocks, per this app note. We're using the STM32F105 with HAL libraries from STM32CubeMX. I don't see the cube able to configure to 13 clocks. Will the STM32F1...

I have a huge accuracy loss (way above what is expected in the datasheet) on ADC reading when increasing the sampling rate. I get that the accuracy is supposed to decrease but I sample at only 200 kHz on the STM32H47AI which is supposed to go up to 3.3MHz

Considering the fact that I can no longer make a difference between waveforms sent at 1kHz (sin and triangular) I am wondering about what I did code wrong in my ADC initialization to mess up my results that much. Below is a 1kHz sin I get for my 200...

How to increase the number of Zigbee nodes in the network?

I am using "stm32wb55rg" with FFD binary stack. Using Zigbee coordinator sample application example. With this I am able to join only 16 nodes in ZC network. Please suggest how I can increase the number of nodes that can join to the network.

Input Capture not consistent (STM32F103C6)

I'm using STM32F103C6T6 to capture input frequency configured on TIM2, Channel 1 (A0).I'm generating 1KHz frequency from Arduino Uno (using tone(Pin, 1000) function) connected to STM32 Pin PA0.Timer Configurations of STM32:Prescaler set to : 10000-1A...

RM0351 - repeating bookmarks

 I remember some other RM suffering from this in the past.JW

Please advise difference between part numbers STM32F100C8T6 & STM32F100C8T6B? In datasheet, suffix "B" is "internal code".but there's no further explanation. Can they be interchangeably used? Please advise. Thanks
