Dear Madame or Sir.We found following undocumented problem on MCU STM32H743.It occures only, if TTCAN mode is activated for FDCAN1:FDCAN1:If TTCAN is activated (LEVEL = 01) and the TX-COMPLETE Interrupt of TX-BUFFER 1 is activated, and the TX-COMPLE...
Hello, I am not an embedded systems guy, so please bear with me.I have an issue reading data to my STM32G071 nucleo board from an external device via SPI using DMA. To do this I used code from an ST example project.I suspect the issue lies within the...
I got the Mikroe Fusion for STM32 V8 per recommendation from the STM32F302x product page. I'm trying to debug using the onboard debugging unit but having trouble finding ANY documentation to do this. Since this device is linked and recommended by S...
I would like to access the UID_BASE (0x1FF1E800) register from the CM4 core, but I run into a HardFault. I checked the reference manual and page 137 says that memory map is reserverd for the CM7.Is there a way to read it somehow to map that System Me...
HelloI'm developing firmware for a STM32F413 on a PCBA. The controller needs to:- control two ADCs via one SPI,- control an LCD via another SPI,- de-bounce a switch using a timer and - communicate with a UI interface over a UART.The SPIs and the UART...
Hi there,I'm trying to implement a software interrupt using the STM32L432KC. I want to trigger an interrupt when I reach a certain point in the code. Unfortunately I didn't find any helpful example.Once I tried to set bit37 in the IMR2 register.SET_B...
Hi, I am using stm32l0 series. my device will work with battery. I want to put it in sleep mode when it is not working so that the battery does not run out. Then I want to be able to see the battery status. But I have no idea how to do it. What I wan...
Hello,I have a custom STM32F439VITx board running at 60MHz clocked from the HSI. I have three devices on I2C3, two of which function correctly, the third, an mb85rc64 non-volatile memory, fails on both read and write operations.The I2C is configured ...
I ask about G071 exampke code, but nobody replies, then i try use more specific question. My test display is round 240x240 SPI LCD. TE signal is fmark .(one pulse per frame)In partial or block window send method RAM in display is updated on random pl...
