PWM Block
Posted: Sun Jan 18, 2015 6:11 pm
Anyone got the Edison PWM Block running, i've using C++ but not sure of the best way to set the PWM and write to the output channels.
Hi ant.innit,
I've been using the PWM Block from SparkFun for Intel Edison recently without any issue in C programming.
My code is based on this library :
https://github.com/TeraHz/PCA9685/tree/master/src
which I adapted as a C library in my program, with some minor modifications.
Also I had to make some precise measurments to retrieve the exact value of internal oscillator, which was closer to 27MHz than 25MHz in my case
There won't be much difference between using the library in C or C++ in terms of performance, both are efficient enough
Regards
