I am trying to communicate with an external flash chip “MX35LF1G24AD” using QSPI protocol, but I am not able to. Simple test I implemented was to read chip ID to validate I could get data from external flash (I am using OCTOSPI1 interface). From manu...
Hi,I'm using STM32F103RB (NUCLEO-F103RB) and I configured the clock system in STM32CubeMX.I am using HSI as the clock source, and the APB2 timer clock is running at 64 MHz.I want to generate 20kHz PWM signals using TIM1 Channel 1, 2, and 3, and I’ve ...
Hi Support Team,I am using the STM32F103RCT6 MCU in my design, I am facing one issue related to the software reset using "HAL_NVIC_SystemReset();" api is not working and the IDWG also not working after downloading the .hex file using the custom bootl...
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?
