PIC32Lua

Lua for PIC32 Processors.

A newly created Git playground.

2015/05: Also notice the new PIC32LuaMZ playground here.

CHANGES

V0.1a

- NEW: port "names" ("pic.port.A", "pic.port.B", ...)
- NEW: PortLatch(<port>, <state>)
- FIX: some cleanups in asIO.c (stdio, stderr, io.write, ...)

V0.1b

- NEW: binary number representation with, e.g.: '0b001110'
- NEW: timer tick-time variable (100ns, by default) in "pic.TIMERTICK"

V0.2a

- NEW: simple delay function in msec and usec; TimerDelay(<usec>, [<uflag>])
- SD-CARD FUNCTIONS:
    - NEW: check card insertion: CardDetect()
    - NEW: mount card: CardMount()
    - NEW: find first file/dir: FindFirst(<name>, <type>)
    - NEW: find next file/dir: FindNext()
    - NEW: almost complete (but yet not fully tested) IOLIB sd-card integration;
             reading, writing, seeking, ..., can all be done through Lua's iolib
- NEW: interface to IOLIB's console interface. E.g.: io.write, io.read, ...

V0.2b

- NEW: configuration bits now in code (by popular demand ;-)
- FIX: PortDir() now returns the correct values (~TRISx)
- AD CONVERTER:
     - NEW: select analog input pins; ADPins(<state>)
     - NEW: select multiplexer input pins; ADMux(<muxa_pos>,<muxb_pos>,<muxa_neg>,<muxb_neg>)
     - NEW: select Vref; ADRef(<vrefcfg>)
     - NEW: start conversion and read result; <adval>=ADRead()

V0.2c

- NEW: limited support for "dofile()" and "loadfile()" (no real error checks)
- FIX: wrong buffer index in asUART1.c (UART1_RXBUFSIZE replaces RXBUFSIZE)
- FIX: stupid buffer overrun error in asUART1.c and asCON.c

V0.3a

- FIX: support for C32 v2.01
- CHG: CardMount() does not check for card insertion anymore
- CHG: minor code cleanups (replaced default 'stderr' output by 'stdin', ...)

V0.4a

- NEW: support for chipKIT-Max32
- NEW: console and serial port UARTs can now be swapped
- FIX: minor cleanups (still a LOT to do ;-)

V0.4b

- NEW: SD-card boot file support; boots function "BOOT32()" in file "BOOT32.LUA"
- NEW: added SPI pin documentation
- FIX: corrected pins for SPI1  
  SD-card now works on both SPI interfaces

V0.4c:

- FIX: 64-bit timer bug (lock-up after 430s)

Have fun
