• No.5, 6, 7, 8, 9, 10 and 11 is Port I/O PIN of PIC Microcontroller that is PORT-RA, PORT-RB, PORT-RC, PORT-RD, PORT-RE, PORT-RF and PORT-RJ respectively. Its Pin arrangements are shown below.


-5-

• No.12 is PIC18F8722 Microcontroller. • No.13 is LED that is interfaced with RH0 Pin for writing

program to test operation of board simply.

• No.14 is Port ICD2 to download Code Program into Microcontroller and uses with external Programmer such as ET-PGMPIC USB.

• No.15 is Jumper to select interfacing signals between I/O Pin; RC6 and RC7 and Driver MAX232.

• No.16 is RESET Program Switch. • No.17 is Connector Power Supply of Board and must be

interfaced with Power Supply that is not higher than 5VDC. If Power Supply is higher than 5VDC, component maybe damaged.


-6-

• No.18 is Switch to select mode operation between RUN Mode and PROGRAM Mode. When shifting Switch to PROG position, it will ON/OFF Pin that is used to program Code Data into Programmer to program the designed data; when shifting Switch to RUN position, Pins will come back to normal I/O Pin.

• No.19 is LED to display state of Power Supply internal Board (Power Status LED).

• No.20 is Connector Power Supply to use with Board ET-BASIC I/O.

Source Code Programming

To program Data Code Program into Microcontroller of Board ET-BASE PIC8722 (ICD2) must use external Programmer such as ICD2, PICKit2 or “ET-PGMPIC USB” Programmer of ETT. It makes us interfacing Cable Program into Connector ICD2 as shown in the picture below. Other detailed description about application of Programmer can see in the User’s Manual of the used Programmer.
