I have configured the comparator 2 PB6 on the STM32G071RB Nucleo board. It is configured for rising edge interrupt. As soon as HAL_COMP_Start is called on the COMP you can see the EXTI rising edge interrupt flag immediately go high. (well not immedi...
Hello,We have run into some issues regarding SPI in interrupt mode, especially when building with optimizations turned on. We are running SPI at 21MHz.The situation:We transmit one byte using HAL_SPI_Transmit_IT. This immediately triggers a TXE inter...
Hello.I have designed my own STM32H747IGT6 board.And I created a simple project with STM32CubeIDE to confirm its operation.In this project, CM7 is a program that simply blinks the LED in a while loop. (CM4 is just code generation) while (1) { ...
If I have a bare h753 MCU on my custom board. What connection in terms of communication peripherals and connectors do I need to achieve. Basically, I want to bootload the MCU. The next step is to be able to program, monitor, test simultaneously. From...
I'm using STM32G030F6 chip. Try configure on pin PA8 external interrupt. When it make in UI "PInout & Configuration" tab it works as expected. But I want configure it from code. Here example: Added to main.h pin naming #define FC_ON_Pin GPIO_PIN_8...
Hi everyone,I’m working on a custom board design using an STM32H753AII6 in the UFBGA169 package. I need to include external SDRAM but want to keep my PCB footprint as small as possible, so I’m leaning toward a BGA-packaged SDRAM rather than the typic...
Hi,I am trying to erase and write to stm32u545 flash.The memory partition is such that, I am dividing each Flash bank 256kb into secure and non secure regions.first 8 pages are secure and rest of the bank are non secure.I am running my code from Bank...
Refer to datasheet DS12288 Rev 6(STM32G474xB STM32G474xC STM32G474xE), where Table 5 (Temperature sensor calibration values) describes that the high temperature calibration sampling point used for internal temperature sensor calibration is 130 degree...
Hi everyone,I’m working on a custom bootloader for an STM32H750 and need some help. My goal is to be able to update the unit from USB and for doing so I use an external eeprom to store the MCU FW and load it into RAM at startup. The main reason to us...
Hey everyone,I have an odd problem with a STM32H563VGT6.I have configured several GPIO as inputs with no pull-up/ no pull-down. The pins are wired to an external 10k pull-down and a DIP-Switch which is directly connected to +3V3. (screenshot below).W...
