Hi ST.Can help to advise on how to interpret on the body marking of the of the IC below? And what is the red marking on the chip itself? Are there any changes on manufacturing process regards to this part? STM32F723ZET7 Thanks.
I want to monitor my 4.2V battery and cant find any MCU which can convert such high voltage . It will be even better if it has differential ADC [can do 1.5-4.5].Previously tries STM32F303C8T6 but all the ADC pins are only 3.3V Tolerant. Its my first ...
Hi everyone,I am working on a project where I need to interface an external ULPI PHY (FUSB2805) with the STM32H745 for high-speed USB communication using USB CDC. This is my first time working with an external USB PHY, and I am facing some difficulti...
I maid a custom board with ST32H745 mcu. The board is working fine but the ethernet part is not working. The Ethernet part is exactly the same as the Nucleo H745ZI reference design. The code and Ethernet part working fine on Nucleo board. I checked...
I am Implementing RNDIS Over USB using the Stack provided by STM32 Team. The Data Received at the EP OUT Function is Correct for the First Few Bytes of Data, Post that the Data is Jumbled/Incorrect. Not Sure whats the Reasons though.I tried Verifying...
I have a STM32WL55JC part that spends a lot of time in shutdown mode. It's woken by an alarm on the internal RTC. However intermittently it fails to fully wake up.This is almost certainly a hardware fault - certain PCBs are more susceptible than othe...
Hello Team,Can you please suggest a development, Evaluation board for STM32F405?ThanksAnuj
Hi I'm using the STM32F446RE with the latest FW Package - SMT32Cube_FW_F4 V1.28.1, and i have a MCP3221 connected to an I2C port.Its a strange ADC that returns a sample every 2 bytes when its setup to send data to the I2C master. There are no address...
For my current Project, I decided to go with the STM32H7B0VBT6 from the STM32H7B0VB family. However the 1.4MB SRAM of the MCU was too little for me, so I've chosen to go with an external SDRAM (IS42S16400J-7TLI [64 MBit | 8 MB). Now I wanted to get t...
Hi, I am new on STM32 and I started a product prototype using STM32F769-Discovery. I developed all software using default clock configuration, which uses HSE. Now I want to change to HSI, but USART is not working ( Not true, only works when board res...
