I'm using STM32H743VGT6 QSPI drive an AMOLED screen. AMOLED read sequence need IO0 line send and receive data.(Picture 1) But I checked the H743 Reference manual, it says in the single mode, IO0 just output, not input.(Picture 2) How do I fix to make...
Hi, there; I am migrating the DCMI from stm32h743 to stm32u575, on the stm32h743 chip, I can make the dcmi work perfectly, but on the stm32u575 chip, I cannot make the DCMI work, neither the GPDMA for DCMI. Anyone met the same issues? The codes are g...
When I use usbuser to power the Nucleo-H563ZI board, I have add jumper in the usbuser at JP2.Then ld5 and ld7 light up, but the mcu firmware doesn't start properly. I need to add jumper in the CHGR at JP2 then the mcu firmware can start. According to...
Hello,I am running into a weird behavior where EE_ReadVariable32bits call in EEPROM EMULATION library fails when optimization is turned on with Os setting. With Os setting it works only once after full chip erase and fails to read (resets) after any ...
Hi everyone, I’ve been following the official ST guide for setting up USB Power Delivery (PD) Sink on an STM32 device, as outlined here: Getting started with USB-Power Delivery Sink. I successfully compiled and flashed the firmware onto my NUCLEO-G07...
Hi ,I am using STM32G4 to receive USART data from external interface and USART buffer overrun when USART interrupt conflicts with Flash Erase operation. As mentioned in STM32G4 Reference manual , in single bank mode, any read operation while writing/...
Software Environment:Windows platformConfigured using STM32CubeMXCompiled with STM32CubeIDEHardware Platform:NUCLEO-U545RE-QMCU: STM32U545 (Cortex-M33, ARMv8-M)Test Objective:We initially noticed slow SPI performance (CS low to CS high) and decided t...
For my project I am using the LPUART on an STM32U545 and 585, currently I am using the normal GPDMA and this works like a charm in normal run mode. However I want to be in STOP1 and receive UART communication. As per the reference manual the GPDMA is...
Hello,After some investigation was found that memset has different behavior executed from different places in flash. Data and instruction cache are off! Micro used is stm32h743xi.Function is called with following arguments --> memset(dummy, 0, 64)Its...
Hi,I'm aware of the BOOT0 pin which is available on most STM32 MCUs and allows to select the device being booted from Flash.Now my problem is, once shipped to an end user, this flash can't be updated easily. So it would be better to have a more simpl...
