* - display the specified channels for a cycle of pwm_timer
|
||
|
|
* - before using the function show, init must be called
|
||
|
|
* - for every cycle of pwm_timer, show must be called
|
||
|
|
* - show buffers the selected channels, so it returns immediatly, as long as
|
||
|
|
* the internal buffer is not full
|
||
|
|
* - when the buffer is full the function blocks until another pwm_timer cycle
|
||
|
|
* has processed the current channels
