Resolved! the pin to pin compatible part of stm32f103vet6?
Hi,I'm using stm32f103vet6 in my design, but due to the limit power budget, the MCU consumes much power(60mA per MCU , while I used 2 chips in my design), result in frequently triggering over current protection. Is there pin to pin compatible STM32L ...
Fail to adress memory
Hello, I'm attempting to establish communication between an STM32L552CET6 microcontroller and an external flash memory. When I manually initiate communication, the component responds to the microcontroller, indicating no hardware issues. However, whe...
I2C peripheral Multi-master mode
Hello all,I'm using STM32L552 MCU and its I2C peripheral to control a board. I'm facing a phenomenal which I not quite sure how to handle that. I have a pretty old fan controller chip on the board which is kind of really slow. Not only it works with ...
STM32L562 and Sky High eMMC S40FC008 fails MMC_PowerON() with rtn code 4
I have a custom board using the STM32L562Q BGA package processor. I have a high speed capable eMMC part with an 8-bit data interface. The STM Cube generated code seems to be correctly beginning the init and ID process, however after the 3 different ...
SD card doesn't work with stm32L552ZET6
Hello everyone,I have been using for a long time the stm32L496ZGT6 in a customized PCB with an uSD card module. Never had any problem interfacing the card. Due to the shortage of supply during the pandemic situation I bought a couple of stm32L552ZET6...
FDCAN on STM32U5 and STM32H5 - serious FIFO/queue and ID filter list size limitations
I am wondering if anyone notice that FDCAN on STM32U5 and STM32H5 MPUs has FIFO/queue size limited to 3 (three!) elements only.AN5348 - FDCAN peripherals for STM32 product classes does not mentioned that anywhere. The max FIFO/queue size discussed in...
stm32L5 write flash problem
Hi. I am testing flash read and write operations.In the main function, when I write 1 to address 0x08006000, I can correctly read back 1. However, when using FreeRTOS and performing the same operation within a task, I read back garbled values (such ...
