attempt to reduce space usage - remove unecessary code - ifdef "extra" code - pass data through globals instead of functions accessing static data - functions non-reentrant, locate tmps in xdata 2019-04-01 01:29:37 +02:00			`//#define DEBUG_KEYS`

bugfix for keys - initialize count, so that there is no initial keypress at powerup - use int8_t instead of uint32_t to pass new key, since only 1 new key used 2019-04-01 07:55:47 +02:00			`extern int8_t NewKeyPressed;`
