//define dictionary's reference number in the shared_dictionaries.h file
//then include this dictionary file in shared_dictionaries.h
//The dictionary number is literally used as usb transfer request field
//the opcodes and operands in this dictionary are fed directly into usb setup packet's wValue wIndex fields

// PINPORT DICTIONARY
//=============================================================================================
//=============================================================================================

//This file was created based on firmware version of pinport.h and pinport.c
//the close relationship between these two files must be kept in mind when making changes.
//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
//inherently get forwarded to both firmware and app at same time.
//
//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
//for opcode/operand decoding.
