I was trying to change an option byte from the embedded bootloader of an stm32u5 over canFD. Long story short I sent it some messages that were not formatted correctly and It looks like I have bricked the chip. Trying to connect in stm32cubeprog wi...
Hello,I am assisting with the firmware development of a dual-active bridge converter and I am trying to create a phase-shifted PWM signal that will control the switches. Creating the phase shift is proving challenging, but I had an idea that I believ...
Hi,I'm working with a STM32F439 and I set both timers, timer3 & timer4 to produce a 460ns pulse at a 50Hz frequency with their PWM feature. Now I need to be able to control their offset to each other with the ability to set it to 0. But it appears li...
We have a STM32U575xx chip, where I want to read a bunch of voltages continuously.These voltages don't need to be measured at a particularly high rate, nor does the timing need to be strict. So it seemed efficient to run the ADC continuously with DMA...
Hello,I am using the STM32H7S78-DK board and STM32CubeIDE for development. In my application, I am working with UART communication between UART4 and UART7.Objective:I am sending data from UART4 (connected to the Virtual COM port on the board).The dat...
res = disk_initialize(0);printf("disk_initialize returned: %d\n", res);if (res != RES_OK) {printf("Disk initialization failed!\n");v = 8;} else {fres = f_mount(&fs, "", 1);printf("mount returned: %d\n", fres);if (fres == FR_OK) {printf("Filesystem mo...
Hello,I'm just started using a nucleo-h742x. I have configured the SPI and the Fatfs library using the default settings, the SPI speed was configured at speed below 1Mbit/s. The sys clock is below 100MHz.I always get disk_not_ready error when trying ...
Using the STM32F030RC, the program that originally ran at 0x800000 was moved to 0x8020000. After the move, SysTick_Handler() is no longer executed, causing HAL_Delay() to fail. Has anyone encountered this issue before?
Hi,I'm working on a STM32G030C8T6 based personal project and recently done a revision 2 to fix some annoyances and add some status LEDs. Programming and debugging is done via a STLink V3 and the SWD. I've encountered twice the same strange behaviour,...
Hi,I have been reading a few app notes but still a bit confused about some things...A custom board I am working with has an STM32U5G9VJT6Q MCU driving a DSI touch display. The PCB has QSPI and SDMMC but it does not have SDRAM.In the application, the ...
