PWM outputs are great for lighting control, motor
control, or generating analog outputs, but they tax your
microcontroller, right? With the GP-9 you can get 8 channels of PWM
output with minimal overhead on your main CPU. In fact, in many
applications you don't even need a microcontroller! The GP-9 reads 5
analog inputs (for example, pots) and outputs a PWM signal proportional
to the analog input on one of 5 PWM channels. In addition, a computer
can use simple serial commands to read the analog inputs or control 3
independent PWM outputs. In addition, the host computer can take
control of any of the 5 PWM channels that are normally controlled by
the analog inputs. A jumper selects if the device starts in a stand
alone mode or waits for computer commands.
Please note that this is a kit and does require
soldering and basic electronic tools. This allows you to customize the
board to fit your needs. All the parts are through hole, and the solder
masked board is very easy to assemble. If you prefer to "roll your own"
you can also purchase the chip and resonator. Note the chip requires
your own TTL-level serial port and 5V supply to operate.
