The Industrial Raspberry Pi Forum

Dear folks,

I want to modulate a signal with the maximum cycle time of the dio bridge, around ~2.5ms.

ATM im counting the RTC ticks in a main while loop, but hence its not synchronized, there is a periodical gap, where my output signal is one cylce longer.

Therefore i need to be synchronized with the RevPi IO Cycle, but there is no interrupt or other possibility to arrange that behavior, right?

Thanks for your help in advance!

Dear folks,

unfortunately, this is not possible with a Core/Connect. It would work with the Revpi Compact, where we allow 250 usec cycles for the digital I/Os and analogue outputs. You probably see jitter on the PiBridge, which makes the cycles sometimes shorter, sometimes longer. The PiBridge is too slow and insensitive for such applications.
