![]() I’m going to use (again) Processor Expert with gcc and CodeWarrior for MCU10.3. What I’m going to implement here, is how to use an UART to send/receive characters.To have things a little challenging: using interrupts and buffering :-). While I’m using here the Kinetis-L ARM Cortex-M0+ KL25Z Freedom board, it is applicable to any other Kinetis device. It is about how to write *and* read from the UART. But it *is* about using the UART on the KL25Z Freedom board and to do things like printf(), and even more. And I promise: it is doable with around 50 lines of application code :shock.ĪND: I admit, this post title is a trap -). So less is more, and if it is just about the UART. Sometimes I show to much in a tutorial: only writing something to the UART? Sounds boring, so why not adding tasks, LEDs and a full shell implementation to the mix as in this post? Yes, definitely too much to start with at the beginning :-(. ![]()
