use digital out the fastest way with OS

[berguenstein]

Hi,

I'd like to update my digital pins of the Analog Discovery 2 in quite a "fastest" time (1ms for example). The problem is, with a python script, the time let by the kernel is approximately 15 ms.

That's why I ask it there, is there a way to programm it with a sort of a script that would be faster than 15 ms to adapt the output (in a non-regular way, a pulse wouldn't work)?

Thanks for the time spent for help,

Marc

Hi @berguenstein

Unfortunately the communication between the host/PC and device has such unpredictable milliseconds of latency.
You could use DigitalOut function to generate pulses, pwm or custom pattern on the device; or the "ROM Logic" for control loop or state machine.

See the SDK/ samples/ py/ DigitalOut examples.

Hi @attila

Thank you,
unfortunately that's what I thought :')
