Hello, I'm trying to communicate with my RF module through UART interface. However, I get many errors even with low load. I suspect that I have an issue with the way that I configure the clock or the UART. Basically, for the UART functionality I use http://glitovsky.com/blog/?p=300 http://glitovsky.com/blog/?p=300 (I configured the connection as 8N1 at 115200). The clock configuration...

earlier today I was asked by a friend to point him to a document that explains interrupts to him in a simple way. Chapter 2 of the User Guide is a starting point, but a bit on the bland side about why and how, so I dashed this off. Re-reading it this evening I thought that it might be of some use to people out there since interrupts seem to be a frequent cause of questions and dilemma in...


How to obtain and save the return address inside an interrupt?

I am using MSP430F2618 and the IAR Workbench (version 6.20). From time to time I get a watchdog reset. I think I can use the watchdog as a timer, then have an interrupt when it times out. Inside the interrupt I would like to find the return address and maybe even save it in flash. If I could do this, I could find out where the problem is. Would you have suggestions as to how to find out the ...

I know I've moaned before, but potentially the best part that Ti built was the MSP430F2131. It's problems were simple, no SBW interface, no comms. It's plusses were a very small footprint, decent I/O count and reasonable memory. As they've added to their portfolio they've concentrated on the high end big memory high pin count stuff, or the very low pin count, like 16 pin QFN packages, wh...

Hi Folks, Would someone please tell me where to find the calibration values for the temperature sensor for this chip when using 2.5 volt reference voltage? I found a sample code that says the calibration values when using 1.5 volt reference is located at 0x1A1A and 0x1A1C. Surely there exists a document somewhere that illustrates where to find all the calibration values for this chip, but I am ...

The opening line of Groucho Marx song in "Animal Crackers," I wanted to share that I'm putting my MSP430 stuff in storage. I throughly enjoyed the part, the EZ430, but time as moved on and I have adopted a different microcontroller family, Arduino, not to persuade others but to share why. Friday, I was starting a new project but needed some 'glue' logic, power supplies to provide both 5V and ...

Hi, A new project based on MSP430 microcontroller is in process of being finalized. This is a PLC that can be programmed in C. A preliminary description of it can be found at: http://scitec.hubpages.com/hub/C-Programmable-Logic-Controller-CPC430 In these days this description will be improved. I'll add a bill of materials and a file with C-specific PLC functions. The project will be availa...
