Where can I find documentation on how to do this? I want to connect the other controller to RXD/TXD on the Microview and send the Microview commands to display information/data, as well as have the Microview return push button switch input back to the other controller.
I have found the source code for MicroView::checkComm(void) and MicroView::readSerial(void) but that is all I can find. Is there a corresponding “writeSerial()” method?
More important, where can I find documentation on the commands themselves: format, arguments and so on?
The Microview is essentially just a miniaturized Arduino Uno with a OLED screen attached to it.
Code you write for Arduino would work on the Microview, you just need to remember to include the Microview libraries if you want to put data on the display. (You could skip the libraries if you wanted but it would complicate your code.)
It doesn’t look like we have a comprehensive guide for the Microview library, but if you’re just wanting to send and receive serial data, the regular Arduino commands for that will be OK to use. Serial.read() and Serial.write() will work just fine with the Microview and you can find those in the [Arduino Reference under [Serial](Serial - Arduino Reference)](Arduino Reference - Arduino Reference)
