According to "STM32H562xx/563xx/573xx device errata" (ES0565 - Rev 6 - March 2025).There is three revisions (Rev.A, Rev.B and Rev.X).What is the difference?All revisions in the market for now?If so, how can we oreder Rev.X chip in the market?We would...
I am making an adapter between 6‐pin target debug header and 14-pin STDC14 connector. The same cable will be used to program and debug both M0+ and M4 targets.Can I hard-wire SWO (pin 8 ) and T_VCP_TX (pin 14) together? The idea is to have an option ...
I am working on interfacing MicroSD card with STM32H757I-EVAL. I am following the same steps to setup and configure SDMMC1, as mentioned in this video https://www.youtube.com/watch?v=-0kFwp0ao6k @2:56 but there is DMA setting option under SDMMC1 co...
Hi,I am currently working with the STM32F334 and STM32G474 microcontrollers, and I have a couple of technical questions that require deeper insight into how the HRTIM (High-Resolution Timer) operates in these devices.Q1. Can HRTIM generate a high-res...
We set up classic CAN on the stm32h747I-DISCO dev board and listen for interrupts on every message:extern "C" void HAL_FDCAN_RxFifo0Callback(fdcan_handle* hfdcan, std::uint32_t RxFifo0ITs) { if ((RxFifo0ITs & FDCAN_IT_RX_FIFO0_FULL) != RESET) ...
Hello All, I am trying to talk to an FRAM over FMPI2C on the STM32F446 using DMA, but the DMA is not able to "start". I am using the Mem_Write_DMA function in stm32f4xx_hal_fmpi2c.c.When I do a side by side comparison with the Mem_Write_DMA function ...
What's the difference between enabling high cycle flash from option bytes on an H5 versus just using that section of flash by reserving it in the linker instead, apart from the ECC change?
I have an application that debugs correctly when I loads it at address 0x08000000.I'd like to use a bootloader, so I've changed the ld file, and choose, as flash origin, the address FLASH (rx) : ORIGIN = 0x08020000, LENGTH = 1920KBut, in this case, w...
I'm trying to crank up the clock to Timer1 to be able to count high frequency events with better resolution. If I set the SYSCLK to 128 I get a hard fault when my code reaches SystemClock_Config(). Even if I keep the AHB bus at the same speed (64Mh...
Hi all, I am using STM32F7439Zi MCU, I would like to create the master + slave pwm signals with the relation that at the falling edge of the master, the slave's pulse will be started. Both PWM signals has the same frequency, the duty cycle of the ma...
