Hi everyone,I am working on an STM32H523 MCU and I have recently observed some strange behavior regarding the PB14 and PC9 pins. I have the following setup:PB14 is configured as input (I use this for the TIM2_CH2 alternate function, but this does no...
I am using LTDC for interfacing with a TFT LCD. The LCD is connected with 18 bit (RGB666) interface. I have selected the pixel format as RGB565, and I am using a frame buffer stored in the internal SRAM. The frame buffer has been populated with 16 bi...
Hi folks, I'm using one timer to generate a pulse train (TIM4), and a second slave timer to count the pulses (TIM8). This is on an STM32U575.I have this working nicely using a timer with centre aligned mode 3 for the counter mode, with the channel u...
Based on the information found in AN4286 rev 14, I am trying to command to bootloader to start executing the application.The setup is a H573 and a H563 connected over SPI @ 0.5 MHz. The 573 operates as SPI master, and the 563 as a slave. I know that ...
I am implementing a firmware-update mechanism on STM32H755 (Nucleo board, MCU rev U) in which the two flash banks are independent. New firmware is flashed by erasing the "other" bank (which is always mapped at 0x0810 0000 and accessed with the ____2...
I have a problem and currently no clue how to further debug. Maybe one coudl help me. I use STM32f4 to capture with ADC1 3 signals with 1Mhz (so 333kHz per channel) triggered by a timer and transfered via DMA. I have a DMA buffer of 3*2*100 (so 100 s...
Hiya. This is my first time working with custom STM PCBs.I was planning on flashing/programming my custom STM32H7 board (specifically STM32H7A3RGT6) over STLINK and then just do general purpose programming over the USB-C COM Port. However, the TAG co...
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...
