Hi, I do not have any experience with analog mux ICs, But from what I understand it should be fairly easy to get working on your msp430. have you considered using a multi-channel ADC? or have you checked out Digikey for an IC that fits your parameters?

Thanks, GO check out the 43oh.com forums, they have lots of great code examples and a great people to help you out if you get stuck. Here is a Great PWM post on that site

Such old stuff! Looks cool!

Sorry to ask but, do you have any idea where I can find an example that will dim the LED on the MSP430 using PWM? I saw your PWM tutorial but I’m using CCS and I’m really a beginner lol..

Thanks!

hello justin

i am a budding programmer to msp430. i want to control 8:1 analog multiplexer through msp430fg439 for my EEG recorder project. and give detail about analog muliplexer ic which should allow micro volt signal

yes you should be able to drive ACLK with the VLO

Hi,

Thanks a lot for the info, can we drive ACLK timer interrupt out of that? Anything we should particularly keep in mind?

Best,

What compiler are you using?
It looks like you are using either CCS or IAR, this code is not compatible with either one

you may have to enable the interrupt another way (gie bit), and you will have to change how the interrupt is called (#pragma)

please let me know how you get it to work and i will update my post to add your changes

Comment on MSP430 Uniarch mspgcc or mspgcc4? by Justin

From my tests that I have done, I have changed in a few of my source files to include msp430.h, and it compiled without error
These are the flags in my Make file -Os -Wall -g -mmcu=msp430f2013 .
I also tested on my build the g2211, and it worked with out a problem.

Just to be safe i used the same files you did to do a test compile, including rake and make
both compiled with out error.

My guess is, something happened during the build……. or something is not linking right

the only thing i can think of doing is uninstalling and reinstalling msp gcc

but if things are still not working, i would try the mspgcc mailing list, and ask them on whats going on.
