Hi IN the past it seemed the periodic recalibration of the DCO in the MSP430 had been removed for some reason. Has that been reinstated? Or is there some means to programaticaly force a recalibration?
I had been using the DCO as the UART clock source. I found that even at 9600 baud - in *outdoor* applications the typical temperature changes would cause the async comm to stop working. I confirmed that the problem was frequency drift by using a scope and resetting the MSP430 - thus recalibrating the DCO - would always fix it. If there is some reason an automatic, periodic recalibration can not be done, in my present application the MSP430 always initiates the communication and it is infrequent so it if there was a routine to force a recalibration that would work for me - otherwise I will need to use an external accurate clock source for baud rate generation. Thanks Steve
