I’m designing a board with the STM32F401RBT6 and have decided to use a 48 MHz TCXO for the HSE clock.I’ve written a simple "Hello World" program that communicates through USART.the TCXO i used : TG2016SMN 48.0000M-MCGNNM3 Observations: When using the...
While debugging on the Stm32g474, I enabled write protection. Now I want to disable it. It seems like this is impossible with the Stm32Cubeprogrammer? It will not allow me to enter an invalid address or an address that ends before it starts. How am I...
Hello, I am seeing an issue with an STM32U5 battery powered system in the field. I use IWDG to reset the device in the occurrence of a software issue, and put the device into standby mode to sleep for periods of time before being woken up by either R...
Hi everyone, My requirement is as follows. I must be able to implement Basic DHCP, HTTP, HTTPS, MQTT, FTP, UDP, TCP etc., So I thought of choosing an MCU which has standard working examples and thereby it'll save more time than to adapt a code to a p...
I am trying to create a Client that communicates via Ethernet on the PHY LAN8720 chip. The program has an error that does not run automatically when the board is powered on or the chip is reset. If I use debug, I have to press RUN several times to be...
Hi,I have connected a MAX-M10M module to an STM32H7 MCU ( it's custom board) by UART port. I am able to send data to GPS module and also receive config data of it but not able to receive NMEA packets. I only receive the first byte and then the HAL_...
Hi, I have some code running on an STM32G431 that does a loop in which it reads on a pin on port GPIOB, shifts the value and writes the result on GPIOC. I have trouble really understanding the timing I see on the oscilloscope. The code is: ldr ...
Hello community! What are the simplest ST uC with CAN feature? Yours suggestions will be welcome! Many thanks and Regards!
Hello, I currently have an IAR Embedded Workbench 8.22 dongle license, but this version does not support STM32G4 since the MCU series was introduced later. Upgrading to a newer IAR version is not an option due to budget constraints, but functional sa...
I searched about STM32H563 maximum current consumption of AD converter when run mode on datasheet and reference manual.I could't find AD converter's maximum current consumpsion on datasheet and reference manual.I want to consider external LDO for VDD...
