Resolved! STM32F105R8T HAL Busy and missing data buffers.
I'm using STM32F105R8T to send serial buffer commands to an HMI display.MAX485 chip was used for communication. There are pre-defined command buffers and updatable data buffers. Those buffers are sent through a RS485 bus at the baud rate of 9600. The...

Sleep mode with FreeRTOS enabled
I want to be able to make the STM32G474 go to sleep when certain conditions are met.I've created a small project to test the feature. The `app-freertos.c` file is like this:#include "FreeRTOS.h" #include "task.h" #include "main.h" #include "cmsis_os....
Trying to move over G0 DRP example code, the UCPD tracer program stops seeing the board
I am trying to build an application with a SNK and DRP usbc port, using a USBPDM1 and a DRP1M1 with a nucleo g071rbI have successfully run the DRP example application, but when I try and add the functionality to my sink application stm32cubemonitor-u...

usart DMA interrupt faster than buffer update
Hi All,I use DMA IDLE Idle line and circular mode to receive usart buffer, and process data in rtos，but when I get an Idle event, sometimes RTOS read buffer will get some empty data, but wait a little bit times, the buffer will be updated, so when I ...
usart interrupts vs freertos polling
My application has a low priority usart receive function - meaning that if characters are delayed it's no big deal. I've been using interrupts with a callback receiving one character at at time with a read always outstanding. I process flags and b...
Resolved! Why do I not receive a USBPD_NOTIFY_SRCCAP_SENT notification?
I am trying to set up a sourcing power delivery port on an STM32G0 system. I have set up switching of VBUS, and when I connect up a sinking device my system detects it, sets up VBUS and starts sending source capacity messages.Log:<Connect source to p...
