Hello,I'm working with STM32F429ZI nucleo board, and I would like to flash my program using UART (USART1 or UART3 via a usb to ttl converter) instead of ST-Link.I understand that STM32 has a built-in bootloader that can be used for flashing via UAR...
Hello, We have a STM32H755 with an FRam (similar to SRAM) module attached to the FMC. We have been seeing CPU exceptions when the M4 core tries to access (read only) the same memory location the M7 core is writing to. So, it seems that the FMC does n...
Hello,I am working on an STM32C011 (Nucleo-like custom board) and trying to use I2C1 with the following pinout:PB7 → I2C1_SCL (AF14)PC14 → I2C1_SDA (AF14)According to the reference manual / datasheet, PC14 can be mapped as I2C1_SDA (AF14).I connected...
Hi everyone, first, our setup: We're currently developing a custom-made board using STM32U375CGU6Q. We've configured the ADC1 for continuous scan conversion of 9 channels - VSENSE (int. temp. sensor) being one of them - and use the GPDMA to transfer ...
Hello,Is there any chance ST could provide examples or guidance on interfacing a CSI (MIPI) camera with Raspberry Pi Camera Module 2 NoIR cameras?From my initial research, it seems the CSI connector uses the same pin layout as Raspberry Pi cameras. H...
Reading STM32U5A5 Rev. ID returns 0x3003 using STM32Cube HAL API that is not listed in Reference Manual (RM0456). What is the revision of this product? The Reference manual lists only 0x3001 as revision X and 0x3002 as revision W.Thanks.
Hello, I'm using WinUSB and I'd like to program the flash memory at address 0x0800c0000 in 256-byte increments. This works fine the frame but every frame after this gets written to blocks in increments of 1024. It seems that if one needs to push more...
I've spent some time recently trying to prototype a small project based on the STM32H503 which would need to have the ADC and DAC running simultaneously with multiple channels of analog I/O via DMA. I was able to get this all coded up but discovered ...
Hi,I'm using an STM32H7 microcontroller and need to get the RTC working.I set RTC_OUT to 1Hz and set the LSE to a 32.768Hz crystal, and inserted the CR2032 battery.When the microcontroller is powered (VDD 3V3), I see the waveform oscillating at a fre...
Hello everybody,I'm trying to get from a pulled up state / driven up state to a tristate pin without losing the charge that is on that pin.It seems to me, that whenever a pullup is deactivated (PUPDR), that STM32 will first discharge the pin and then...
