Getting OSError 261 from machine.Timer

Post by hsxsky » Sun Apr 21, 2019 5:06 pm


I tried to use multiple timers.
When I start fifth timer I got OSError 261.

In micropython documentation: ... er%20esp32
"Virtual (RTOS-based) timers are supported."
I think I can start multiple timers.

I checked espressif documentation. ... timer.html
"The ESP32 chip contains two hardware timer groups. Each group has two general-purpose hardware timers."

Is it the source the problem?
Or do I search the solutions elsewhere?
