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...
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...
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...
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...
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...
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) ...
Dear support,We use 3 cans in STM32F767ZI board and have some problems with filter & banks configurations.We use FilterScale = CAN_FILTERSCALE_32BIT and CAN_ID_EXT for transmit/receive data. We would like to receive data by the following way: CAN1 sh...
Hi everyone,I have some issue with the Flash loader demonstrator V2.8.0. It has worked several times before. Now when I started the tool, the first step picture 1 (connect to devise) it works fine. But the in the second step picture 2, I can't see an...
