Incompatible with Uno R4 Minima and WIFI #27
Description
I tested the following sketch using a TB6600 on the Arduino UNO R3, R4 Minima, and R4 WIFI. The R3 works perfectly, but the R4 boards do not. The motor attempts to turn but simply stutters. If I instantiate a WiFiServer in the sketch for the R4 WIFI, the motor still stutters, but it does so at a much slower rate than when the WiFIServer is not instantiated.
