The rpm sketch is capturing every change in signal on both the a and b channels. So on the 800 PPR encoder I tested with it will process 4* 800 signal changes per rev. If you are going to 5000 rpm it¡¯s probably best to just use the Z channel
which signals once per rev. Can you share more details of your encoder such as the PPR and which channels it provides?
Thanks Mark, seems strange to get a error?at ~200 rpm.
But I will investigate (ha).
I will need upto 5,000 rpm.

Here is a link to code on GitHub, tested against Arduino UNO and MKR Wifi 1010 using an Omrom E6B2-CWZ6C rotary encoder bought off eBay. Runs upto ~200rpm before detecting errors which could either be the encoder or ability of arduino to keep up with interrupts,
but since both tested arduinos see errors at roughly the same level I'd guess its the encoder.
