Decoupling & Vcc Pin Configuration for STM32 MCUs
Hello Community,Reaching out to you for feedback on the attached configuration for Vcc on my new STM32 based DAQ board.My objective was to reduce the inductance to the Vcc pins of the MCU (STM32G0B0RET6 64 LQFP package). Hence I clubbed three pins:A)...
STM32U5A9NJH6Q: When PB4, PB14, and PB15 are set to EXTI with interruption, EXTI15 interruption is activated by the signal of PB14
Hello , I have an issue in STM32U5A9 IN EXTI interruption.When PB4, PB14, and PB15 are set to EXTI with interruption, EXTI15 interruption is activated by the signal of PB14.And EXTI15 interruption isn't activated by the signal of PB15.All EXTI settin...
STM32H563ZGT6: Use both Flash banks for 1MB code
Dear community:I am currently using the STM32H563ZGT6 chip, and my code capacity exceeds 512KByte. When programming through CubeIDE, I can only burn to the 512KByte Flash of Bank1. May I ask if this chip can use Bank1 and Bank2 as a whole (as I have ...
Resolved! Struggling with USART1/LIN interrupts on STM32F3
I have a design using USART1 on an STM32F3 as a LIN slave receiver using the old standard peripheral drivers from ST Micro. The code is too much to post here, but I have LIN Break Detect and RX Not Empty interrupts enabled, and for some reason under...
FDA903D : I2c Write procedure
FDA903D : I'm facing issue with I2C write procedure. I'm writing to the slave device (FDA903D) from my custom designed board with Infineon controller being the master device . The datasheet of FDA903D is not clearly mentioning how to do I2C transfer ...
Resolved! STM32H747 Internal Temperature Measurement and Calculation
Hello, Friends, I am using ADC(16 bit) to measure the STM32H747 Internal Temperature and VrefInt based on external reference voltage (VDDA 3.3V, Vref+ 2.5V). The VrefInt result is 1.221V, which looks good. However, the temperature result is 150C, whi...
Newbie trying to Blink w/STM32H750B-DK
Hello,I acquired the STM32H750B-DK development board. Initially, when I connected it to my PC, it would power on with a display and interface. However, for the past month, it no longer turns on at all. When I connect it to my PC, a folder opens with ...
PWM and ADC conflict
Hello, I'm new to STM32, I bought a Nucleo board with a STM32F334R8T6I want to generate a PWM of 10kHz and read some data in ADC channel, unfortunetely, there some conflicts between this two and I can not generate a PWM with more than 5kHz.I need som...
Resolved! H723V + HS ULPI possible damage
I am currently working on a H723 based HS USB device with external USB PHY (USB3320,USB3340,USB3300 tested).While testing i have noticed that seemingly randomly between debug/flash cycles HS USB stops working with usually no activity on the bus but t...
