Effectively deleted old dictionary call function/files.
Created lua_usb_vend_xfr function so lua can directly send and receive
vendor setup transfers.
Dictionary calls are more like function calls now, and all args aren't
required so the LED can be turned on for example in lua like so:
dict_pinport("LED_ON")
general format is:
dict_name( opcode, operand, misc, datastring )
Also added ability to store opcode's return length in shared dict library
files with RL=number in the comments following the opcode.
Negative numbers designate OUT transfers, positive for IN.
Default value can be determined by each dictionary's calling function.
Decided pinport is 1 for SUCCESS/ERROR CODE.
Also have default return data means with second byte giving length of
return data in bytes that follows.
dictionary call function reports any errors reported by the device and
returns any return data from the device excluding error code / data len
Now time to start implementing some of these dictionaries on the device.
packet arrives. Had issue with return data on STM32 not being properly
aligned when the rv array was only 8bit. So defining it as a 16bit array
and then pointing a 8bit pointer to it seems to be an easy fix for now.
Ready to start working on pinport dictionary. Need to get lua code
working on a lower level handling the dictionary calls. Need it do do
things like fill out the wLength and everything for me so one doesn't have
to remember every detail about an opcode/dictionary before calling it.
Realizing code was heavily segmented based on how big/many operands there
were and how big the return data was. This is hard to maintain, need lua
to resolve this issue, and make everything easier to script. Thinking
opcode/dictionary calls need to be more like a function call. Passing in
necessary args only, and returning data instead of succeed/fail.
underlying hardware/mcu. Created avr_gpio.h to define AVR pin registers
in a struct fashion similar to what's common with ARM code. Doing that
makes things much easier to abstract in pin macro 'functions'.
Added define to Makefiles that flags pinport_al.h which board is targetted
for build.
Tested and able to turn on/off and pull-up LED on all 3 builds.
