We found some time the UART interrupt call back function (HAL_UART_RxCpltCallback) will shut down but the IRQ function (UART5_IRQHandler ) still working. Because we have add the counter in call back function and IRQ function , when the communication ...
I have a STM32H7 running ST X-CUBE-CELLULAR6.0 package on a BG96 modem.It works fine, but some time I need restart the modem and service. while current cellular_modem_start/cellular_modem_stop API are not enough to restart the whole service, for exam...
Hello.In my design, I need to communicate the MCU on my board with two other boards by using Ethernet connection. For this purpose, I am planning to add the Ethernet switch IC LAN9313 in my design.In the reference design document (given by Microchip)...
Hi dear friends... I have a big problem with lwip and tcp library in the client side... I created a server in pc and configure my board as a client ( using stm32f407 ). When i turn my board on while the lan cable is plugged and server is running, ev...
Hi, I'm working with an STM32F446VET MCU. The goal of the F446 is to get data from some sensors and store it on an SD Card and send it at the same time to a COM port. I was able to make Windows to recognize the USB/COM port (https://community.st.com/...
