Other Parts Discussed in Thread: CC2540

Hello,

I'm now waiting for my CC2540 to arrive and wanted to ask wether UART0 is accessible on one of the debug headers?

Thank you and cheers

    As far as I know the following pins are accessible on the debug header:

    P0_0, P0_1, P0_6, P0_7
    P1_2, P1_3, P1_4, P1_5, P1_7

    Therefore you can access USART0 in SPI (Alt2) Mode or USART0 in UART (Alt2) Mode, but as the accelerometer is also connected to these pins you have to define the usage.
