00:00 <peterm6881> ok here's the situation

00:04 <peterm6881> given there is no question they are using UART1 for the Bridge, I think they must be using PD1 to PD4, in Multiplexing Function 3. Its the only GPIO providing UART1 thats not exposed to pins

00:08 <peterm6881> So, if I'm right, and we're restricted to Multiplexing Function 3, currently enabled, then we have to use PE7 - PE8, which is UART2 in Multiplexing Function 3

00:11 <peterm6881> PE7 is UART2 TX, PE8 is UART2 RX

00:12 <peterm6881> PE9 is UART2_RTS, PE10 is UART2_CTS

00:15 <peterm6881> i'll email mangobuge to request a schematic of the RC3 to confirm this

00:38 <peterm6881> erm....R3C
