DShot is sent by the DShotRMT library. The problem is: ESP32-C3 only has two RMT channels that are capable of transmission.
In contrast, the Xtensa ESP32 has 8 RMT channels and is capable of outputting 8 DShot channels.
In order to add more DShot channels to ESP32-C3, I rewrote DShotRMT to use only one RMT channel, but change the pin that the RMT is connected to in a round robin fashion. This means one RMT channel can be used to output nearly unlimited number of DShot channels.
(the code is still hard coded with a 8 channel limit)
