Reckstyle 2:e2adb7ab2947 3
Reckstyle 2:e2adb7ab2947 4 Please consider that although it is an embedded envrionment we are NOT creating a HARD-TIME real time system - delays can be dealt with
Reckstyle 11:9e56d52485d1 5
Reckstyle 11:9e56d52485d1 6 Sensors are mapped on the global variable sensorsCheckSum,
Reckstyle 11:9e56d52485d1 7 which multiplies the sensor number by itself to then decode,
Reckstyle 11:9e56d52485d1 8 which sensors are off and which are on
Reckstyle 11:9e56d52485d1 9 ie. if sensor rightright - sensorChecksum = 1*1 = 1
Reckstyle 11:9e56d52485d1 10 if rightright and rightcentre - sensorChecksum = 1*1 + 2*2 = 5
