If the bit in Pending Register of STM32 is not cleared.

If the bit in Pending Register of STM32 is not cleared.Will interrupts trigger all the time?Will the Interrupt service function always run?

Serial communication via UART on SMT32L475 Discovery kit IoT

on the SMT32L475 Discovery kit IoT, I would like to implement the following commands from Arduino:Serial1.begin(BPS, SERIAL_7N2); Serial1.print(msg)   while (Serial1.available()) { t = Serial1.read(); wmsg[ct] = t; ct++;   *bufflen = ...

P-L496G-CELL02, Could the Quectel BG96 replaced with Quectel EC25-E module ?

I'm curious to Know before purchasing this Board a few things,Our need is , the Board shall be reliable to adapt the Other Quectel Modules as well like for Indian Bands i.e EC25-E modems from Quectel.The issue is in India, LTE-M is not operational, s...

I2C BUSY

I am using STM32F407 Discovery Board and I'm generating my project using MX Cube   I'm doing testing on I2C sensor that is MLX 640 which is used for taking thermal image , so basically we are are reading frames of thermal image via I2C on every 1 sec...

LSE clock start-up problem

Hi, i'm trying to use the LSE clock with the RTC but it doesn't start until i make a state reset or run the code under debug mode.I have read all other posts of LSE problems in the forum and found a lot of info, almost everything related with hardwar...

Use timer`s chain to generate N impulse`s

I do some serial interface clock with timers chain on stm32f407.Thats work, but generate little bit lower count of impulses. where is my trouble? len is about 16 384, overall pulse count len*16.I miss about 200*16=3200 pulses.Thank You!TIM2->PSC=0;  ...

Real time debugger needed

Hi, Currently i am using STM32L082CZ processor and debugger tools as ST-LINK V2 B2019-51.When I enter debug mode, it will update the status/flag/watch variable upon reach breakpoints. The debugger window show on Keil won't update during run time, i...

What is the relationship between adc clock and sample rate? [STM32H7]

I understand the sampling rate for 16-bit can be a maximum of 3.6Msps depending on the chip package, number of ADCs, oversampling, and interleaving or regular.. I'm doing a regular 3 channels 16-bit scan from a single ADC, no oversampling.The app not...

Currently, I test STM32L562 Discovery Kit in low power environment. I tryed some programs and now I lost the original firmware loaded when i bought the board... My question is: Where I can find this program (in Bin or Hex) to loaded again?
