Uart read line is a helper function for implementing ascii protocols that send data line by line.
Well the stm32 part is unreadable. In some cases these isr detects conditions, for which a sleeping freertos task should be waked up with at least possible latency. The rfid communicates using rs232 and transmits a 12-byte ascii string. The visual studio projects in the freertos distribution were created at various different times and therefore use various different free versions of the visual studio for c/c++ ly you do not need to use the exact same version of visual studio as used to create the project, and visual studio will provide instruction on re-targeting a project if there is a version mismatch.

St stm32f407vet6 uart pc hello world! . From what i can see hal uart transmit would've worked with the f4 hal v1.4.2 if it weren't for hal lock huart .the rx thread would lock the handle and then the tx thread would try to lock as well and return hal busy. And about uart, this is related to freertos, which is making getchar work. Freertos programming on linuxposted by snetmonster on ma hello, i am a student and a newbie to freertos, in my class they asked us to do a project which is creating a propulsion board, that should drive a 2 wheels based robot.
