MCU stop working suddenly (LED driven by the MCU is off), can not be programmed anymore

2022-10-06
Hi, I use STM32H7A3LIH6Q in my project. Now we have two prototypes and I could program and run them at the beginning, LED is on or blinking. Later when I started to test the DC/DC converter, both boards had LED (driven by MCU) off, and can not be pr...

What voltage should be clamped on for analog input, vref or VDDA? At what condition positive injected current happen when the pin is used as analog input?

2022-08-18
Hi, I'm using STM32H7A3, and I’m a bit confused about injected current for pins used as analog input. In our design, I used both 5V tolerant and 3V tolerant pins as analog input. And VDD=3.3V, VDDA is connected to VDD with a bead. And Vref is 3V. And...

Does USART has to be RS232 to use system bootloader

2022-03-11
Hi, I'm designing a board in which the communication between STM32 and the host is UART over LVDS. So RS232 transceiver is not used in the design. And we want to upgrade STM32 firmware remotely through the UART LVDS interface by the host. But accordi...

Question related to motion sensor LSM6DSOX

2019-11-06
Hi, We need to use motion sensor LSM6DSOX for position tracking. We can not use GPS in the system, and the position accuracy we need to achieve is 1 m after moving 11 meters. So I have a question related to LSM6DSOX :In the datasheet, the output is l...
