I wrote code for my micro:bit in makecode.microbit.org. Idea is to use radio communication and send each micro:bit message. So my question at first was how many messages can get just one micro:bit?
Internet say this:
Messages received are read from a queue of configurable size (the larger the queue the more RAM is used). If the queue is full, new messages are ignored. Reading a message removes it from the queue.
So my question is: how to find how much RAM memory is used on my micro:bit using makecode?
