Hi helick, Some radio require CTS/RTS control pins of RS232. Can you send us a link to SS900 radio datasheet?
What is the oscilator you are using in MSP430? external cristal? what is the frequency? You could try to lower the baud rate to 300bps just for testing purposes. Hope this helps, Pedro On Sat, Jun 14, 2003 at 05:18:36PM -0400, helick wrote: > Hi all, > > I am having a little problem. > I am using my msp430f149 to go out and get some data out of my solar car > and transmit it out using a RF data radio which understands rs232. > The program in this message illustrates how I am trying to acomplish this. > I created a dummy char array filled with 'a' chars, then I just try to > send it out.
