can USB baudrate more than 9600 under EZ430_PLATFORM ?

Shali,

Please see this post:

thanks jason,

I have seen that post, but there seems no metion about baud rate of EZ430 board. my question is whether the EZ430''s back UART  baud rate can be more than 9600bps

The code that implements the back channel VCP uses a baud rate that is set at compile time.  It is not possible to change it dynamically.

Based on Jim's response, I am confused by Shali's original claim that it works at both 4800 and 9600 baud.

Jim, are you sure it won't work at 4800 baud?

I see now, the receive baud rate is set as 9600bps in the fireware of EZ430. so it dosn't work  if I change sending baud rate more than 9600bps. the baud rate 4800 just a half of 9600, so sending with 4800 baud rate and receiving with 9600 baud rate may be no problem. thank Jim  and Jeff

From the backchannel UART in the LaunchPad, I dimly remember that the baudrate can be below 9600, but 9600 is the maximum the timer/software UART in the TUSB chip can do. (the hardware UART is used for the communication between PC and FET). Maybe it's the same on the EZ430.
