- Tue Jul 14, 2015 7:45 am #23230 It doesn't seem that the 2 usb serial devices I have PL2302, and cp210x have driver support that let me see 74880 baud. Looking at the driver for ftdi doesn't look like that works either. Has anyone gotten this to work? And if so what serial adapter and software are you using?
Thanks.

- Tue Jul 14, 2015 10:35 am #23242 I've been able to receive serial data at 74880 baud with a (most likely fake) ftdi breakout board using a python script (I just used some random script from github). The script does not work with the CP210x on a nodemcu 1.0 dev board. I did not test any of my PL2302, so no idea if they'll work.
Most terminal programs won't work at 74880 baud, since most of them use the termios.h functions, which only defines standard baud rates.

- Tue Jul 14, 2015 2:03 pm #23254 Looking at it more, there is a utility by the makers of cp210x so you can create custom baud rate aliases. So I should be able to make 64000 baud actually 74880. http://www.silabs.com/products/interfac ... x?tab=info for BaudRate configuration.

Code: Select allsudo setserial -v /dev/ttyUSB0 spd_cust divisor $((24000000/76800))


and connect to the port at 38400 baud in eg Minicom.
