ADCSWTrigger

Readme
 
This is a C language project that demonstrates the analog to digital converter (ADC). main1 samples one channel, the accelerometer Y from PA22. main2 demonstrates using the sequencer sampling two channels, the accelerometer X from PB19 and the accelerometer Z from PB18. main interfaces the MKII joystick sampling two channels, the joystick X from PA25 and the joystick Y from PA18. This example also inputs from the joystick switch.
