MSP430F5529 and RFM12b used together in General Posted February 7, 2018 The line concerning watchdog was copied from a program we wrote with our teacher, haha. I bet, he doesn't even know how to code himself *face palm*. But, i googled it and the posts there say that the line "WDTCTL = WDTPW + WDTHOLD;" should stop watchdog. However, others say that "WDTCL = WDTPW | WDTHOLD;" Which one is the right one? Secondly, I am reading P6.5 - in the byte P6 the "x" (00x0000). So, I have to shift it four positions to the right in order for bit0 to be the value I want to read, if I understand this correctly. I do not have my MSP with me at the moment, but I will do some trial and error today and post my "results".
