Various changes to STM8 SWIM code to make more versatile allowing SWIM
pin to be located effectively on any STM32 GPIO pin. Still haven't
touched an AVR implementation, but made place holders so it can compile
for AVR at least. These SWIM changes aren't heavily tested, mostly just
made sure could flash SOIC-8 STM8 CIC via CIC CLK.
Beginings of JTAG code to configure CPLDs. Currently only tested state
change and scan out reading MachXO-256, 4032/64v, & XC9572/36XL CPLDs
Tested and working on inlretro6 v1.0p, stm adapter, & avr kazzos.
Older devices with flipflops will apply 5v signals to JTAG pins but time
is mostly minimized by keeping signals defaulted low unless actively
changing states or scanning data.
Still need to verify scan in working, probably move TDI/TDO long strings
to buffers instead of 32byte PBJE data array. Also need smarter PBJE
host code to keep track of current state and come up with PBJE register
values without hard coding them..
But things are working fairly well so far with SWIM & JTAG
implementations. Had some issues where I thought jtag pin toggling was
getting optimized out, but I must have simply had the logic analyzer
speed set too low and was missing pin changes that can be as quick as
40nsec with space optimized code. Current inl6 code is ~4400Bytes,
without optimization it's nearly 50% larger at ~6550Bytes..!
Optimizations seem fine in testing and with logic analyzer running at
50Mhz which is good because the GPIO registers are set as volatile so
they better not be getting optimized away!
Have separate lua modules now in scripts/app folder
Dictionary calls are now their own lua module
firmware now capable of calling multiple different dictionaries
have firmware & lua io and nes dictionaries, able to detect
NES and famicom carts. Created expansion port abstraction so most kazzo
versions behave identically.
Created separate make file for stm adapter and inl6
added PURPLE_KAZZO and GREEN_KAZZO defines back in. They work well enough
for sensing NES vs famicom carts so far. GREEN_KAZZO requires
PURPLE_KAZZO to also be defined. GREEN_KAZZO is also only compatible with
AVR_CORE due to software_AHL/AXL functions specifically written for AVR.
I think things will work if a STM_ADAPTER is placed on a PURPLE_KAZZO and
both those defines are made as only real difference is software tying of
AXL and X_OE. But haven't tested this aside from ensuring it compiles.
Have correction to pinport_al.h that will commit immediately after this.
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.
