input configured pin to detect frequency.

I am using STM32F103C8, in which I want to use pins which are configured as digital input to detect the square wave frequency or the frequency at which the pin is reading high and low.Is it possible without Input capture direct mode?

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...

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
