Re: [Tinyos-help] Using UART1 instead of UART0
Dear Eric, I have soldered the RX pin of the device which should be interfaced, to PIN#24 of FT232BL. This way as I mentioned in my pervious email, it is possible to send bytes using 'printf' function to the sensor. That device is using 5V CMOS level, so I connected the wire that comes from PIN#24 of FT232BL to a 3.3 to 5V level shifter, Since I think pin 24 of FT232BL comes from PIN#2 from BUFFER chip. I have done the same thing with TX of my device, I have connected it PIN#25 of FT232BL, I am pretty sure that pin is going to UART1RX of MSP430. Now, after a week, I was not able to receive any data in TinyOS from UART1. I tried to use component Msp430Uart1C() but it receive event seems to do nothing. I would really appriciate if you or other people who are reading my email to give me some help in this regard. I wish there was something like `scanf()` fucntion which could let users to read from UART1.

If so that is RX and connected to UART1TX so you probably have the sense of the pin wrong. UART1 uses P3.6 and P3.7. You will have to figure out how to mess with it to get the USART doing the right thing.
