How can an ADC input read influence the encoder input ?

Hi!we use STM32G473 with 4 timers for 2 motors, for each motor we use 2 timers connected with ITR , the first timer is used as encoder input to hold the position, the second timer interrupts on each edge of of the encoders and calculate the speed.Wh...

Hi,I have STM32CubeIDE 1.7.0 issue whereby I can connect either ST-Link V2 or V3set to our custom board that has STM32L462RET6 MCU. Same with STM32 Cube Programmer - can't connect - target not found. Inside IDE, there's problem launching GDB serv...

Made an ISD1820 Voice Recorder and Player Module with a single board stm32f401 is posible?

I want to made a simple Voice Recorder and Player Module, i found an interesting article here:https://community.st.com/s/article/how-to-play-audio-files-using-stm32-part-1?t=1675535162773 But it´s focused to STM32G0, and i have stm32f401, i´have trie...

Problems with UART transfer using DMA on STM32L471RGT6

Hi , I am using DMA/serial port transfer with RTS /CTS handshaking to transfer between 490 and 506 bytes from variable dma_buffer. The byte stream is terminated with \r\n\0 . the code is below : while (transmit_complete_flag !=1 ){;} // wait here un...

EEPROM in FLASH emulation for STM32G07x - how to use original EEPROM emulation pre-prepared code without HAL support ?

I'm using just LL drivers for my project, unfortunately eeprom_emul.c file function EE_Init needs stm32g0xx_hal_flash file with HAL_GetTick and HAL_FLASHEx_Erase funtion. What I'm doing wrong ? Is there any example without HAL level functions for EEP...

I am using STM32G0 MCU in a new project. I would like to know if is possible to use a LPTIM in free running mode and read the counter value just like a time stamp. I intented to use the reading for measuring the time between two isrs. BR Gilberto

MPU6050 I2C accelerometer and gyro readings returning odd values with stm32l432kc nucleo board

I have implemented a small I2C driver for stm32l432kc board and tried to use it to read from a couple of MPUs I have first:I can read single WHO_AM_I register correctly giving 0x68 asserted in the debugger I can write to the POWER_MGMT_1 register to ...
