Resolved! STM32f429I Discovery schematic
I bought a second-hand stm32f429 discovery board, here is its image. I found 4 schematics on ST website (MB1075b~MB1075e), but I can't confirm which one corresponding to my discovery board. Accroding to the information shown on board , my board is DI...
Resolved! Hello, I have some problems programming a custom STM32F417 board.
The Flash of the chip can't be programmed. Mostly the error is that writing the first byte failed. But sometimes it is able to write a few bytes. It even worked like 3 times. The behavior is consistent over STM32CubeProgrammer and ST-Link Utility, an...
i have stm32l100 i want to make pc usb keyboard, do you have schematic and hex.

how to get stm32-v3set with Stm32CubeProgrammer to program STM32L041?
PC connected to STM32-V3SET via USB. PC COM3 sees the STLINK.STLINK is using CN7 UART TX and Rx lines to L041 USART2 configured pins PA2 & PA3. GND too.L041 has BOOT0 pin on a wire, to allow high or low level at reset.L041 has SWD-loaded program i...
Resolved! I am designing a high-performance line-following robot, and I would like to know if my schematic is correct?
I am designing a line-following robot that also avoids various obstacles (two digital infrared (IR) sensors), but I am a bit confused with my schematic since I am a beginner in electronics, and that is why I would like to know if my schematic is corr...
Misprint in UM2407 (Rev 2). In table 20 (CN9 pinout) pin 15, the STM32H7 pin should be PE9 (it appers PE0).
I don't really know where to inform this.Thank.
Resolved! Conflict between SMPS and LDO regulator during startup on STM32H7 microcontrollers.
I am working on a PCB design with a STM32H735IG uC, and I would like to use the integrated SMPS to provide VCORE directly, without the LDO. This corresponds to figure 19.2 of RM0468 (the reference manual). In this configuration the VFBSMPS is connect...
Resolved! [RESOLVED] Why IAR EWARM debugger resets STM32F7 in a weird way
Apologize for IAR specific question, hope someone here can shed some light on my problem. I've tried to ask IAR support, but looks like they have a long weekend or whatever.I have a bootloader at 0x08000000 and main app at 0x08008000.The bootloader ...
