responding socket strips must be organized in the following pitch format:

In the graph the socket strip X1-X4 and then the first two pins of the socket strip can be seen. Pin 1

of strip X1 corresponds to terminal X1_1 (see Mega128 Pinzuordnung).

Module Memory

The C-Control Pro 128 Module provides 128kB FLASH, 4kB EEPROM and 4kB SRAM. A supple-

mentary EEPROM with an 8kB memory depth and an SRAM with a 64kB memory depth is mounted

on the application board. The EEPROM can be addressed by an I2C interface.

Note: Detailed information can be found in the IC manufacturer’s PDF files on the C-Control Pro Soft-

ware CD-ROM.

ADC Reference Voltage Generation

The Micro Controller is equipped with an analog-to-digital converter with a 10 Bit resolution. This

means that measured voltages can be represented by integral numbers from 0 through 1023. The ref-

erence voltage for the lower limit is GND level, i. e. 0V. The reference voltage for the upper limit can

be selected by the user:

5V Operating Voltage (VCC)

Internal Reference Voltage of 2.56V

External Reference Voltage e. g. 4.096V generated by a Reference Voltage IC.

If x is a digital measuring value then the corresponding voltage value u is computed as follows:

u = x * Reference Voltage / 1024
