Hello,

Can anyone tell me the max baud rate for the maple serial output?

I need to send data at 115200,8,n,1

Thanks

I think you are missing a zero datasheet says 2.25 Mbit

Hey NewtoMaple!

Are you asking about the hardware serial ports (USART) or the Serial-over-USB connection? Both will will definitely go up to 115200 baud; for the SerialUSB you just have to change the host-side terminal settings to get those speeds, while for the USARTs you need to pass the speed as parameter to the SerialN.begin() function.

hi pagercam,

I think you're right. I need to go back and check the documentation but I think the max baud rate on one of the uarts is 4.5Mb/s, and the other two is 2.25Mb. I checked the code and found a bug where we capped it at 225000. I'll post fixes later.
