 * - 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
