It will only be interrupted by occasional UART interrupts. Then add the C11 and C12 signals to Analyzer2Go and make another recording. Remove the breakpoint and restart the program. Replace the code in your main source file with this.

We will now use the interrupt-based transmission to free up some of the CPU cycles. While the transmission is active, the program cannot do anything else and has to wait for it to complete. Try typing some text in the terminal window and see how after every 4 characters the program echoes them back: Now we will explore the UART timings using a logic analyzer. Sorry, your blog cannot share posts by email.We will show how to use direct mode, interrupt-based mode and DMA-controlled mode and will use a logic analyzer to compare the precise timings of various events. We'll assume you're ok with this, but you can opt-out if you wish. This website uses cookies to improve your experience. STM32 tutorial: Efficiently receive UART data using DMA
