General Discussion / TinyScreen+ and TinyZero with 433 MHz long range radio tinyshield
« on: December 04, 2018, 11:25:32 AM »
There was already a post about this: http://forum.tinycircuits.com/index.php?topic=1639.0 in 2016...
Basically, the demos still won't compile for M0+ (atsamd21).
Personally, I would be happy to use the "classic" tinyduino but the effective data rate when using the hardware along the lines of the provided demos is nowhere near the upperbound quoted in the documentation (256 kbps).
After all, any data transfer has to happen in blocks of (even in the original commented out version that's just 255 bytes at a time):
Without some trick for transferring data faster (is there some setting I am missing?), and given the need for a two way protocol to synchronized the data transfer I can't figure out a way to get above a couple hundred bytes per second, so I'm sure I am doing this wrong :-)
