Multiple LaunchPadXL F28377S

yacine ould

Hello,

i have Two questions :

i have 2 launchPad connected to 2 different USB ports how can i affect the x program for the 1 USB port and the 2 for the other.

Do you know if it's possible or if some modbus library's exist for the F28377S ? i can use the uart to develop one ?

Thanks for all your response.

Hi Yacine,

If you plan to connect 2 launchPADs to the same computer and both connect to CCS, you should take a look at the following wiki articles:

With regard to MODBUS, please see the following E2E thread:

Thank you,
Brett

Hi Brett,

thank's a lot for your fast response, it work's fine .

just a little precision , can I use the UART ( SCI) to communicate via a transceiver for the RS485 ?
( i look at the modbus link it's was clear).

Thank you,
Yacine

Hi Yacine,

"...can I use the UART (SCI) to communicate via a transceiver for the RS485?"

This is my understanding. You can also use Bruno's code as a reference.

SCI is a serial communications peripheral used for 2-wire asynchronous communication (1 rx line and 1 tx line, where the clock is embedded inside these data lines). A transceiver can then be used to interface these lines such that each line turns into RS485.

Thank you,
Brett
