// This header file serves two purposes:
|
||||
//
|
||||
// 1) Isolate non-portable MCU port- and pin-specific identifiers and
|
||||
// operations so the library code itself remains somewhat agnostic
|
||||
// (PORTs and pin numbers are always referenced through macros).
|
||||
//
|
||||
// 2) GCC doesn't always respect the "inline" keyword, so this is a
|
||||
// ham-fisted manner of forcing the issue to minimize function calls.
|
||||
// This sometimes makes the library a bit bigger than before, but fast++.
|
||||
// However, because they're macros, we need to be SUPER CAREFUL about
|
||||
// parameters -- for example, write8(x) may expand to multiple PORT
|
||||
// writes that all refer to x, so it needs to be a constant or fixed
|
||||
// variable and not something like *ptr++ (which, after macro
|
||||
// expansion, may increment the pointer repeatedly and run off into
|
||||
// la-la land). Macros also give us fine-grained control over which
|
||||
// operations are inlined on which boards (balancing speed against
|
||||
// available program space).
|
||||
|
||||
// When using the TFT shield, control and data pins exist in set physical
|
||||
// locations, but the ports and bitmasks corresponding to each vary among
|
||||
// boards. A separate set of pin definitions is given for each supported
|
||||
// board type.
|
||||
// When using the TFT breakout board, control pins are configurable but
|
||||
// the data pins are still fixed -- making every data pin configurable
|
||||
// would be much too slow. The data pin layouts are not the same between
|
||||
// the shield and breakout configurations -- for the latter, pins were
|
||||
// chosen to keep the tutorial wiring manageable more than making optimal
|
||||
// use of ports and bitmasks. So there's a second set of pin definitions
|
||||
// given for each supported board.
