Are there program calls for these in B4r for the ESP32.?
I want to sample an analog (1 sample per mS) and measure frequency based on a square wave into a DI derived with external hardware from the analog signal.
What approach would I use with B4R?
At present, with conventional Arduino the analogRead() interferes with the Digital interrupt, so B4r may be the solution.
Yes,I've been thinking about addlooper for a while. ,I'll give it a try thanks.. Is the count rate deterministic, in other words if the same addlooper program was placed in a lot of ESP32s would the count/period be the same in all of them? I see that the frequency of the count is 1.75MHZ for the 80MHZ ESP32.. What actually determines this?
