Thank you for both quick replies - much appreciated. I now understand that there is greater variability unit-to-unit than I assu= med, however, this it not a problem, just requires that I include a mechani= sm for determining then storing in information flash the required unit-spec= ific constants.

Re: Consistency of DCO parameters across multiple samples of a given par

DCO is not accurate indeed. That's why TI programs DCO values during manufacturing. Some kind of calibration is inevitable.

Consistency of DCO parameters across multiple samples of a given part number?

I am working on a project that uses MSP430G2452IPW14 (14 pin TSSOP package.) At initialization, I set MCLK and SMCLK sourced from DCO and set DCO to my chosen clock frequency (I did not rely on Info flash segment D calibration parameters, as those didn't yield the frequency I require.) I was surprised to find upon building my second prototype of the project that the DCO frequency, using the ...

I need to measure the impedance of an antenna setup and am told a Vector Network Analyser is required. For a 1-off use I am reluctant to outlay money to buy one and even the rental fee is high for such a device. Is there another way to measure impedance that will give me the same result? TIA Peter

About a year ago I made this stepper controller for my son's rotary table on his mill. I used the FET430UIF at the time as I've been lead to believe that wires to an off board chip from a launchpad just would not work. FET debugging with the FET430 was a real pain as I could not set more than one break point at a time with an MSP430G... chip. So this time around I figured I would try the...

Is anybody programming the MSP430 in Forth? For beginners there is 4e4th, "Forth for education", see http://www.4e4th.org http://www.4e4th.org/ and there is a special IDE for incremental programming, the 4E4th-IDE, including flasher. No IAR or other tools needed, see http://4e4th-ide.org http://4e4th-ide.org/ - for now it works only with the MSP430G2553. There are other Forth versions avai...


number of rotary encoders with the Scan-IF interface of MSP430

Just a questions to the Scan-IF interface of e.g. msp430fr6989 or msp430fw428. I am just in the beginning phase of a new project and have not used this interface before. How many rotary encoders (quadrature enoding) can I connect to them? It is not really clear. It has 3 channels and only channel 2 can count up and downwards? So I can use it with just one encoder? A alternative woul...

Hello, I have been trying to use EZUSB in a Linux VM using VirtualBbox. I attach my EZUSB to the vm successfully. But Ubuntu Linux doesn't detect it for some reason. I tried to use it directly to a Linux box (bypassing the VM) and it works fine with mspdebug. I believe people have tried it in VMWare workstation and player without success. Any pointers? Thanks. --=20 Cheers...

I am using a MSP430FR2111 with IAR Workbench 6.5 or 7.4 when it is installed. I find that I cannot alter the pins to toggle up and down. I have cleared the lock. There is no problem with my PCB as I can toggle a led artificially. If I remove all components and the track for the pin, it still does not toggle. I have tried a number of pins and also a number of boards. I was concerned about the ...
