member tutorials error - PWM
« on: March 03, 2009, 01:41:38 PM »
http://www.societyofrobots.com/member_tutorials/node/231

this tutorial is very useful but I found an error

at the page that I linked above there is something like this:

Code: [Select]
TCCR1B = (1 << WGM13) | (1<<WGM12) | (1<<WGM11) | (1 << CS10);
but TCCR1B register doesnt have WGM11 flag

it sholud like like this:

Code: [Select]
TCCR1B = (1 << WGM13) | (1<<WGM12) | (1 << CS10);
TCCR1A = (1 << COM1A1) | (1 << COM1B1) | (1 << WGM11);

Hi.

I wrote the tutorial so thanks for spotting any errors.

PWM and Timers are rather unportable from one controller/Timer to another - with different bits in different registers etc. So rather complex.

Can you let me know which processor you are using, and which Timer you are using - then I can update it.

Thanks in anticaption.

I think he is right........
TCCR1B only has WGM12 and WGM13....
At least the ATMEGA32 and ATMEGA8 you have in the tutorial are by this....
For whom the interrupts toll...


P.S. I've been inactive for almost a year... Don't give promises but I'll try to complete my tutorials. I'll let you know when..

Cheers!
