PPM_QUADRATURE_DECODER.C
output channels connected back to four digital inputs to simulate two Quadrature
Decoders feeding signals into the BL4S100. The PWM and PPM outputs are adjusted
through a menu system to simulate the movement of a Quadrature Decoder. The results
of the Quadrature Decoder inputs are displayed continuously to show the effects of the
PWM and PPM outputs.
The high-speed Quadrature Decoder counts the number of
rollovers that occur (one per 1000 counts). The low-speed
Quadrature Decoder displays the current count in the
register.
Once the connections are made as shown, and you compile
and run this sample program, change the frequency/
direction for a given Quadrature Decoder via the Dynamic C
STDIO
speed channel and the register rollovers on the high-speed
channel.
