Hello,I'm having an issue with the STM32L4A6(1Mb) and the dual-bank.First of all, I tried with the NUCLEO-L476 and a simple blink led. It worked fine.Now, my project is based on a STM32L4A6, but the firmware doesn't start in BANK2.For simplicity, I d...
I am using an STM32H747i-Disco board for a time critical application. I would like to periodically output simple text messages to the display.but I don't want to use an RTOS, so TouchGFX is not an option. In LCD.c there appear to be no functions to s...
Hi, Im new to STM32 and Im writing a bare metal spi library however for some reason when I try to change the SSM bit in code it doesnt seem to work. Im able to change the SSM bit in debug mode. void SPI_Enable(SPI_Com* spi) { SPI1_CLK_EN; //Reset...
Hello All,I have received a PCB which is used in a battery pack that i am working on. Unfortunately the CM does not communicate any more and the last he told me was that they did not flash the devices. The PCB has basic functionalities like displayin...
Hi,I'm trying to program one custom board with STM32G0B1RET using original STLINK V3 and STLINK V2 without succes.My schematic is very simple as you can see on the image: And the response all time is: Not STM32 target found.. if I use SWD port. If I ...
I have designed an L476 into a simple controller (BMS) and am trying to use the opamp and ADC and comparators to read the current, and implement a hardware fast overcurrent protection.The opamp is working fine in PGA mode G16. I can see as I inject 2...
I'm trying to program a virgin SYM32G0B1 with the code I've developed and successfully run on the NUCLEO-G0B1RE/NUG0B1RE$AU2 development board. I'm using the STM32CibeProgrammer 2.20.0 software and an FTDI cable (TTL-232RG-VIP-WE with the Vcc line co...
I am using an STM32G4 microcontroller with UCPD and the USBPD middleware. I was following this tutorial (same as AN5418 https://www.st.com/resource/en/application_note/dm00663511-how-to-build-a-simple-usbpd-sink-application-with-stm32cubemx-stmicroel...
Hello,We have ordered STM32G431VBT6 microcontrollers from different sources both online and local but while testing we were getting a voltage drop at source after isolating the whole PCB the issue was found to be localized to the microcontroller. Aft...
Hello,I am currently testing the MT25QL512ABB flash memory on an STM32H747I-DISCO board.The board has two of these flash chips, and I am attempting to operate them in dual mode.I am using the driver from the official STMicroelectronics repository ava...
