19 C-Control Pro IDE

It is important to closely study the pin assignment of M32 and M128 prior to programming since

important functions of the program design (e. g. the USB interface of the application board) will apply

to specific ports. If these ports are re-programmed or if the matching jumpers on the application

board are no longer set then it may happen that the design platform can no longer transfer any pro-

grams to the C-Control Pro. Timer inputs and outputs, A/D converter, I2C as well as serial interface

are also connected to various port pins.

PLM-Ports

There are two timers available for PLM. These are Timer_0 with 8 bits and Timer_1 with 16 bits.

They can be used for D/A conversion, to control servo motors in pattern making and to output audio

frequencies. A pulse length modulated signal has a period of N so called "Ticks". The duration of one

tick is the time base. If the output value of a PLM port is set to X then the port will hold high level for

X ticks of one period and will then for the balance of the period drop to low level. For programming of

the PLM channels see Timer.

The PLM channels for Timer_0 and Timer_1 have independent time base and period length. In ap-

plications for pulse width modulated digital to analog conversion the time base and period length are

set once and then only the output value is varied. According to their electrical properties the PLM

ports are digital ports. Please observe the technical boundary conditions for digital ports (max. cur-

rent).
