Dear Champs,
We tried to test UART echo on LAUNCHCC3235MOD for all UART0/1 TX and RX but met no communication on GP03/GP04.
Other UART0/1 TX and RX are workable.
Is something wrong in below setting?
sysconfig on uartecho_CC3235SF_LAUNCHXL_nortos_ccs example:
And the GP03/GP04 connection on LAUNCHCC3235MOD (have removed J11 and J12)
But GP03 and GP04 still do not work.
If you have any suggestions, please feel free to let me know.
Thanks a lot.
Hi Janet,
Jan is correct. That configuration would work on a custom board, but it will not work by default on the LaunchPad hardware.
You can use the available DNP on the LaunchPad to bypass the op-amps. Please see the schematics and layout in the LaunchPad hardware design files: https://www.ti.com/product/CC3235MODS
Best regards,
Sarah
Dear Jan & Sarah,
Thanks for your confirmation. This concern result from LaunchPad hardware. I found it.
We use GP03/04 as UART1 TX and RX on the target board with confidence.
Thanks a lot.
