Add option to disable current sensing for Arduino motor shield

[Aleksandr-ru]

I'm using Wemos D1 R32 board with Arduino L298 motor shield and always getting [ULP-ADC] OPS short detected message.

If I comment out this check in components/ULPADC/UlpAdc.cpp everything runs fine. If I disconnect half of the motor shield pins - fine too.

Tried to add jumpers from A0 and A1 to another A* pins according to available configuration options - no use.

If you select ESP32 Command Station Configuration -> ESP32 with Arduino Motor Shield (OPS and PROG) the CS will be automatically configured for the L298 to work with that ESP32 board. You will only need to add a jumper from A0 ->A2 and A1 -> A3.

When selecting the above configuration option it will ignore all other configuration options related to pin assignments.

add a jumper from A0 ->A2 and A1 -> A3.

This is magic, it works now, thank you!

But why, why nowhere no big warning like "to get started with L298 motor shield add jumpers"...

The docs cover jumpers in the supported hardware: https://github.com/atanisoft/ESP32CommandStation/blob/master/docs/supported_hardware.md#arduino-motor-shield-required-jumpersv

It should also likely be printed in the configuration section as well.

Thanks again )
