Part Number: LAUNCHXL2-570LC43
Other Parts Discussed in Thread: HALCOGEN,

Tool/software: Code Composer Studio

Hello community,

I am trying to make Launchxl2-570lc43 and raspberry pi communicate each other using Serial Communication. If I am right I have enabled the SCI3 driver using HALCoGen for doing the same. I have connected the the SCI3_TX of launchpad  to UART_RX and SCI3_RX of Launchpad to UART_TX of Raspberry pi.

The coding was done and compiled successfully. But no response could be seen. How can I receive the message from  Raspberry pi. Please help

Best Regards: ADVAITH

    Hello,

    Please double check the pinmux configuration for SCI3_TX and SCI3_RX, and check the voltage level of the signals from raspberry pi. The maximum input signal to TMS570 device should be smaller than VCCIO+0.3 (3.6V).
