Hello world :)I found STLINK-V3MODS extremely useful for automation testing (NuttX RTOS). I have ~50 different boards, some of them does not have on-board flashing capability, thus either JTAG/SWD or UART needs to be used.Most of the boards that use ...
I'm attempting to configure SPI1 on an STM32G031. However I must be missing something because there is no data being output. I am trying setup SPI to transmit 16 bits at a time. Any suggestions would be appreciated. I'm running the uC at 64Mhz...
SWV 16MHz, SYSCLK 16Mhz = logging worksSWV 16MHz, SYSCLK 25Mhz = logs gibberish (expected)SWV 25MHz, SYSCLK 25Mhz = logs nothing at allSWV 48MHz, SYSCLK 48Mhz = logs nothing at allWhy would this be?It works with HSI 16MHz, so my wiring and configurat...
Hi everyone,I'm trying to interface a DVP camera (like OV5640) with the STM32F469I-DISC0 board using the DCMI peripheral in 8-bit parallel mode.What I have:- The camera is configured and outputs data correctly via I2C.- I'm using bare-metal code (no ...
While implementing I²C communication between the STM32F446RE and the MPU6050, the communication does not work when running in debug mode. However, if the board is reset by just unplugging and re-plugging the power, the I²C communication works correct...
Hello world :)Trying to upgrade firmware on series of STLINK-V3MODS on FreeBSD, downloaded 3.16.9 package from [1], after running:java -jar STLinkUpgrade.jarI got error message "Platform not supported (freebsd)".Would it be possible to add support fo...
Hello,I have a Stm32h735g-dk card. I did some work and then the connection was broken. I don't know exactly why it happened later, but I didn't play with the pins, I just threw code with stlink via jumpers and stm32cube ide. Now every time I want to ...
Hi,I am currently making a custom pcb that includes an stlink-v3mods in order to program two stm32's.I am encountering a problem in which the stlink keeps failing and drawing a large amount of current. I am struggling to understand why this could be?...
Hello everyone, the STM32F723IEK6 chip on my H755ZI-Q development board is damaged. If I replace it with a brand new MCU, how can I restore the program
Hi, I recently designed a custom STM32F405RGT6 board. It's my first custom board, and I wanted to post the schematic here for some feedback on mistakes that I might have made before I move on to the motor control section.
