I am working on translating code I have already written in Arduino to XOD. My ultimate goal is to facilitate my students understanding of the code. I am finding it complicated. I am struggling with usb-uart. It feels like I will have to make my own patch with a C implementation. Ultimately I have several custom libraries I have written that will very likely become C implementations. My goal is to interoperate with our existing modules so my codes reusability may be limited. Tho it will be posted if requested. Has anyone managed to create a XOD equivalent to the Serial.println(str); using the onboard USB? ---

Hi jose What sort of problems are you running into with UART? I have used it a fair bit. ---

Have you seen the article about [UART communication](https://xod.io/docs/guide/uart-led-control/)? It can give a rough idea of what you need for the project.
