Instructions

87 C-Control Pro IDE

Example connect trimmer to ADC0 and ADC1 with external reference voltage 2.048V

Keypad

For user inputs a 5-button keypad (key cross) is available. The pins on the socket connector Y11 (6

pin) are connected to the switches T1 to T5. Through the jumper JP1 to JP5 the buttons T1 to T5

can be connected directly to the pins of the UNIT (P41 to P45). If another assignment is desired, the

jumper must be removed and the button are connected via jump wire from the socket connector Y11

to the UNIT. The switches are connected to the application board with 47 kOhm pull-up resistors. No

pull-up/down resistors need to be activated in software. Reading a switch in the idle state (not

pressed), a "1" is detected on the port, because of the 3.3V that is carried to the pin though the pull-

up resistor.

LAN Port / Ethernet

The LAN port can be directly connected with an FTP cable to a switch or router. With the Ethernet

interface of the C-Control PRO AVR32Bit a web server can easily be implemented (see Examples).

Furthermore, via the Ethernet bootloader the UNIT can be programmed across the network. The LAN

connector is permanently connected to the pins of UNIT (see pin assignment in the manual).

Relay

The pins on the socket connector Y13 are connected to the relay K1. The relay is switched by an

FET driver, and the "REL" connector of Y13 can be connected directly to a port of the UNIT. The re-

lay is used to switch smaller loads.
