Need recommendation for JTAG connection in STM32 MCU

I am using STM MCU part STM32F303ZET6. Do i need to provide pullup or pull down for JTAG signals? Please help me here with recommendation on which signal to be pulledup or down.Below image is the connection i did for now.please take a look and advise...

STM32F207VGT6 VCP start fail

Hi Mr. and Miss.At present, I use a circuit board designed by myself, using STM32F207VGT6. Initialize the VCP function using STM32CubeIDE. But there was a phenomenon that it couldn't solve. Error Code10 displayed on Windows.Attached is my circuit dia...

Use internal flash and external NOR in one application

I am using stm32h743, my program is too big to fit in internal flash so I have to use QSPI or FMC. My question is that I don't want to put the whole application in external flash since it is slower, are there ways to have my part of the application i...

Hi, I am using STM32H723ZGT6 in my design, Needed the below details: 1. Worst case power consumption by it 2. Suggest an external SRAM IC that is supported by it. 3. Status on availability of it with LQFP package.

Numbers in LCD custom are blurred or disappered

i had some trouble with my stm32 project about custom LCD using HT1622. LCD display all number i want but some position number is blurred or disappeared. In addition, numbers have fewer bit 1 are almost blurry and others is ok, i don't know this erro...

How to toggle GPIO in the PWM Generation No Output mode

HelloI want to use timer 17 of STM32G030K6T6 microcontroller in pwm generation no output mode and toggle one of the GPIO pins.I just started using HAL functions. I am looking for the interrupt function related to the duty setting registry to toggle o...

STM32G474 ADC channel voltage bleed

HiI've noticed unexpected behaviour with the ADCs on the STM32G474RE.The behaviour I have found, is that voltage from one channel can bleed onto the next sampled channel .eg  if channel 1 has a high voltage, and channel 2 is at 0V, I see a large ADC ...

Troubleshooting Low Clock Speed on STM32F39ZI Board

 Hello everyone,I'm encountering an issue with achieving the desired clock speed on my STM32F39ZI-based board. I have configured the clock speed to be 180 MHz using mbedOS and PlatformIO, but the actual clock speed seems to be lower than expected. He...

STM32 interfacing with FingerPrint module through USB

Hello, I have a device that uses an STM32 microcontroller and has a USB port. I am attempting to create a secure access system for this device using a fingerprint module. My question is whether I can connect any fingerprint module to the device throu...

Stm32h7b0vbt6 SWDIO and VCAP are shorted

Hello, so I have designed a pcb using the stm32h7b0vbt6 mcu. After finishing the soldering process and checking thoroughly for any shorts, I tried debugging the pcb. However there was always an error initializing the St link. So I checked for any sho...
