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...

Defined string with 4 characters is sizeof 4 in watch and 5 in compiled code.

So, just out of curiosity, how can sizeof(LOGGER_SERIAL_DEFAULT) be both 4 (in the QuckWatch) and 5 in the compiled code (red line in disassembly) ? It's defined as: #define LOGGER_SERIAL_DEFAULT "----" So in my mind it should be 4 (if the compiler wanted to count the quotes it would be 6) but NEVER 5. http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-fi...

Hai everyone. I am beginner in MSP430, I was watching MSP430 wprkshop videos from Texas Instruments. I was following the steps and the code they explained in workshop in one code where they source clock from VLO and toggle led, I forgot to reset oscillator pending interrupt flag then led started blinking fastly can anyone explain me why. Here is the code snippet. #include

Timer A jitter on G2 LaunchPad

What sort of jitter should I see using ACLK on timer A w/ the 32 KHz xtal in place? I'm seeing ~1.5 us on the falling edge of a nominally 30.5 us pulse. I'm generating a pulse train using timer A in up mode driving LED2. I expect to see jitter in the pulse length using SMCLK derived from the DCO at the 8 MHz calibrated frequency, but I also see it if I change to ACLK for timer A (still DCO fo...

I'm embarking on my first real project, a one shot millisecond resolution timer to control a spot welder. All prior embedded work has been eval board demo stuff. So I'm expecting to get myself in trouble. For this I need: a 4 digit display output a 12 button keypad input relay output trigger button input I would like to use a G2553 part for this. If I multiplex the display and key...
