fix random display glitches with sprite rendering

Josh Goebel 4478b1fe0a fix random display glitches with sprite rendering 
Sometimes the compiler would assign r28/29 to one of our input
variables despite our needing to use that register ourselves. This
fix attempts to prevent that from happening and also cleans up a
few other small details.

- remove unnecessary y_count (-1 register)
- set buffer_ofs_2 inside assembly (-1 register)
- require inputs/outputs to use lower or simple upper registers

Scott Allen babf6893c8 Eliminate "may be uninitialized" variable warning 
Code in Sprites.cpp refactored to eliminate
"warning: 'mask_ofs' may be used uninitialized in this function"
 2017-04-25 15:36:42 -04:00
Josh Goebel b4d8fd8d6f fix register pressure 
- declare a high register clobber

This seems to have the side effect of freeing up a high register and
preventing the error:

"can't find a register in class 'LD_REGS' while reloading 'asm'""
 2017-04-25 15:36:42 -04:00
Josh Goebel 606c80268b tmp variables can be flagged as output only 
- this saves a few bytes
 2017-04-25 15:36:42 -04:00
Josh Goebel 5d428a3a33 Fix buffer underflow in drawPlusMask 
When sRow == -1 drawPlusMask can cause buffer underflow if it's
interrupted by an interrupt that changes memory that it's in the middle
of writing.  Of course it shouldn't be writing to this memory at all.

This fixes the issue.

Josh Goebel e1cce03580 Optimize drawPixel for speed (-20 bytes) 
- Inlined     : 332 -> 358 ops/ms
- Non-inlined : 222 -> 303 ops/ms

Moves most of the pixel offset calculation math into assembly.
Also uses a shift lookup table vs calculting bit shifts on the
CPU (which is slow)

Scott Allen ab1a7b3bdd Add delayShort() function 
Same as Arduino delay() except takes a 16 bit value.
Mainly added to save some code in the library but can be used by
sketches for the same purpose.

Also changed a delay in bootLogoText() to match a previous change in
bootLogo()
 2017-04-25 15:36:42 -04:00
Scott Allen fc61d180d9 Add displayOff() and displayOn() functions 
displayOff() puts the display in low power mode.
displayOn() re-initializes the display after displayOff() is used.

The SPI initialization code was separated from the display
initialization code to facilitate the new functions.

Scott Allen 9bfb499169 Remove "inline" keywords and attributes 
Optimization done by the compiler makes these unnecessary.

Scott Allen 96b53875b5 Eliminate mismatched type warning in drawChar() 
Also changed a loop index from int8_t to uint8_t to match other loops.

- saves 6 bytes compiling Mystic Balloon on Arduino 1.8.1
 2017-04-25 15:36:42 -04:00
Scott Allen 449532f1e9 Add alternative boot logo functions 
New functions bootLogoCompressed(), bootLogoSpritesSelfMasked() and
bootLogoSpritesOverwrite() can be used in place of bootLogo() to
reduce code size in cases where their drawing functions are shared
with the same functions used by the sketch.

New function bootLogoShell() added to provide common code for the
above functions.

Also, the Sprites class functions, and functions used for drawing the
logos, were made static.

Scott Allen 79f24c47cc Adjust location of some braces for consistency 
This is just a source formatting change.

Scott Allen cfb5e89d5c Simplify initRandomSeed() to reduce code size 
Use only an ADC reading from an unconnected pin shifted left 16 bits
then added to micros().
