We are evaluating the Due for a project and it all looks great except for the 64-byte receive buffer for serial communications. I realize the 1.5 code is still in beta and it is a port of the earlier product. Does anyone know if this buffer is going to be increasing in size before the release? I know that the past code has had to run on some very limited hardware -- is that going to be the case with 1.5 or is it just for Due and better? Our project involves a chatty serial protocol running at 115,200, which means we have to poll that buffer every 5 ms or we lose data. We'd be much more comfortable with another order of magnitude and it definitely seems as though the Due can afford that. But if 1.5 is eventually going to run on hardware with 2K of SRAM, I can understand the decision to limit to 64 bytes and we'll look for another platform.
Thanks for any advice.
