thanks, i took the loop out just to make sure i could create a tone change. I feel like if I can get it to change once, then looping it afterwards shouldn't be that difficult. #include "msp430.h" ; #define controlled include file NAME main ; module name PUBLIC main ; make the main label vissible ; outside this module ORG 0FFFEh DC16 init ; set reset vector to 'init' label RSEG CSTACK ; pre-declarat

thanks, I've been trying to do a second loop and can't seem to get it to work properly. I think the second timer option may be a bit outside my scope until i get a few more weeks of tinkering in.

New to msp430. I trying to make it buzz a tone through a piezo speaker I have plugged into 1.4. I want it to change pitch a few times but can't figure out to control the duration. How can I make the tone hold for one sec before incrementing? Here's the code I've written so far. I'm trying to do the increment in a loop. #include "msp430.h" ; #define controlled include file NAME main ; module name PUBLIC main ; make the main label vissible ; outside this module

Thanks, that all looks a bit advanced for where i'm at(i'm only a few weeks into this). If I can use tones to play happy birthday, then i'll be happy. Maybe something similar to opening a music box or a Christmas card and having it play a simple tone based melody. -David

I'm new to the msp430 and I want to make it play a song through a speaker when I push the button. However, I want to do this with assembly code and not in C. I am using IAR embedded workbench to do my programming. I'm connecting a speaker directly to the msp430 at p1.3 and ground. Are there any tutorials on how to do this? Or any assembly code I could look at that does something similar? I looked through the forum topics but could not find anything that matched with what I'm trying. thanks, alanaxis
