STM32G4 ADC clock
Hi, Most of the STM32G4 CubeMX examples configure the ADC clock as synchronous clock mode divided by two,and the AHB ADC bus clock as 150MHZ. If I understand correctly, the ADC clock would be 75 MHZ for this configuration. The problem is that STM32G...
Resolved! How to bring STM32H753XI-E02 Eval board back to its original status?
Hello,Can someone let me know how to bring STM32H753XI-E02 Eval board back to its original status (i.e. factory default)?I tried to implement Quad SPI application and found the Eval board did not work well. The USB port (CN23) did not communicate and...
hallo, I'm programming the STM32F072CBT6. In the programming "STM demostrator gui" screen I check the "after programming Jump to the user program" but after programming the STM32F072CBT6 remain locked.
With some other microcontroller it works propetrly.Why with STM32F072CBT6 doesen't works?
Current consumption of the STM32L4R9I-EVAL Board is too high (180mA/+5V without display)
i am testing the stm32l4r9i-eval board. I removed the Displays and run a small gpio test program. The board is powered over external +5V and i'm surprised about the power consumption of the board. The current at +5V is more than 180 mA.It fall down t...
STM32 I2C Multi-master problem
I'm seeing a problem which seems to be related to the one discussed here: https://community.st.com/s/question/0D50X00009XkgoYSAR/stm32-i2c-multimaster-hardware-bug In my case though I'm not using DMA, I'm just using interrupt driven I2C but the sympt...
HAL_I2C_Master_Receive ?
Dear Members,Is this function :void max30100_FIFO_ReadBytes(uint8_t* Data) { //================READ FIFO DATA REGISTER====== buffer_tx[0] = 0x05;//FIFO DATA REGISTER //page 16 datasheet //write one byte to MAX30100, 0xAE = Write to MAX3010...
Internal Temperature STM32H7 delivers wrong value
Hi all,I need to measure the internal CPU temperature sensor from the STM32H743. I activated the ADC3 using STM32CUBEMX (V. 5.0.1) and selected Temperature Channel.However the calculated temperatures are far too high. When switching on the cooled sys...
Quadrature encoder integration
Hi thereI am trying to integrate a quadrature encoder using STM32 cortex m mcus.I could not get enough clearance reading the manual several times. I don't have an oscilloscope, which is why I need to rely on specifications rather than trial and er...
Send SPI frame through DMA triggered by timer?
Hello.I want to implement low jitter SPI polling of an external sensor with STM32F4Disco board.From ref. manual it is not completely clear if it is possible to do multiple SPI transmissions (send any arbitrary number of bytes) after a single (timer) ...
