//This file is also very dependent on macro definitions in firmware.
|
|
//Any changes to this file must be applied to firmware.

//Don't recommend changing opcodes or anything here, change them in fw first then apply here.

//making this a shared file helps cut room for error as changing opcode numbers here will

//Trailing underscores are trimmed from this file for the host application to allow direct
|
|
//between firmware and host software. Firmware only uses defines with trailing underscores
