We have a working production firmware for the STM32H7B3 that uses a Winbond W25Q01JVZEIM external flash using QSPI in memory-mapped mode to store data and assets for a TouchGFX and other applications.Now, due to internal flash limitations, we are att...
Hi everyone, I'm using STM32G474 with dual-bank Flash enabled (nDBANK = 0) and booting from Bank2 (BFB2 = 1). I'm implementing OTA firmware update by writing to the inactive bank while executing from the active one. The update from Bank1 → Bank2 work...
Hi, what is the best way to wake from Low Power Sleep when an Encoder is rotated?I have TIM2 setup in encoder mode and it works when in Low Power Run. I just want to switch back from LP Sleep to LP Run when it's turned. Looking in stm32l4xx_hal_tim.c...
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...
