AVR & PIC DEM 2


1.2 Main Features

1. Mini USB power supply.

2. ATMEGA16 microcontroller on AVRDEM board. PIC18F4520-I/PT microchip on

PICDEM board. It can be replaced by PIC18LF4520 or 16F877A microchip. All the I/O

ports are extended for convenient access.

3. 12MHz Active crystal oscillator on AVRDEM board & 20MHz high-speed crystal

oscillator on PICDEM board.

4. 10 pin ISP socket on AVRDEM board. 6 pin ICD/ICSP socket on PICDEM board.

5. 24C02N IIC EEPROM on board.

6. LM75 IIC digital temperature sensor.

7. There is a 20*2 character LCD module on AVRDEM board and a 20*2character LCD

module on PICDEM board. Pre-installed 4-digit 7-segment LEDs is beneath the LCD

module. They could function well after removing LCD module

8. ULN2003 Darlington transistors array are used to drive LED segments and speaker.

9. LCD module contrast can be adjusted by LM358 dual OP-Amps or Potentiometers

R28.

10. There are 3 function keys SW1, SW2 and SW3 connected to RESET, PC7 and PC6

pins of ATMEGA16 microcontroller on AVRDEM board, but RA4, RB0 and

RE3/MCLR pins of PIC18F4520 microcontroller on PICDEM board.

11. One power indicator (Green) and four red port indicators are connected to PA0-3

ports of ATMEGA16 microcontroller on AVRDEM board, but RB0-3 ports of

PIC18F4520 microcontroller on PICDEM board.



Chapter 2. Getting Started 2.1 Install the Driver of CP2102 Single-chip USB to UART Bridge

All related software/drivers, installation guide and instructions on how to build a project with the program software can be found on our website under the General Software menu.

2.2 Application Notes

2.2.1 LCD Module This USB-powered module will start running when the power is on. 1. “Sure Electronics” and “V300” (AVRDEM)/”V200” (PICDEM) will be displayed first

upon the powering of this module. 2. “Sure Electronics” will always be displayed on row 1 of LCD. The displaying

information on row 2 of LCD is supposed to be changed as SW1 (AVRDEM)/SW2 (PICDEM) is pressed down. Current temperature in centigrade, current temperature in Fahrenheit and contrast ratio should be displayed in turn.

3. When contrast ratio is being displayed, its value can be increased by 10% as SW2 (AVRDEM)/SW1 (PICDEM) is pressed down at every time.

4. You may send temperature information to PC every 10 seconds, if the board is connected to the personal computer, and then you could see information in Hyper Terminal like shown in the following. Current Temperature

11.6Centigrade 24.0Fahrenheit Note: 11.6 and 24.0 is only a reference value.

2.2.2 LED Display To use LED display, remove the LCD module from the board first. This USB-powered module will start running upon the powering. 1. “Sure Electronics” and “Ver1.1” will be displayed first upon the powering. 2. The displaying information on LEDs should be changed as SW1 (AVRDEM)/SW2

(PICDEM) is pressed down each time. The displaying information includes “SurE”, “V200”, temperature readouts in centigrade and Fahrenheit.

3. When SW2 (AVRDEM)/SW1 (PICDEM) is pressed down, all the information, which includes “SurE”, “V300”, temperature in centigrade and Fahrenheit, should be displayed in turn.

4. You may send temperature information to PC every 10 seconds. If the board is connected to the personal computer, and then you could see information in Hyper Terminal like shown in the following:

5. Current Temperature 6. 11.6Centigrade 7. 24.0Fahrenheit


AVR & PIC DEM 2 Note:

1. 11.6 and 24.0 are only for reference only. 2. If ATMEGA16 microchip on AVRDEM board is going to be programmed by

AVRSTK500 programmer, demo board should be powered on before the 10-pin ISP socket is plugged into program interface. Otherwise programming may fail.

2.3 How to Communicate between PC and Demo Board

This demo board can send temperature to PC every 10 seconds. It is desirable to install CP2102 driver first. The next step would be to check which port that demo board is connected. The following steps show how to find the port (COM &LPT). 2.3.1 How to Find the Right Communication Port Right click “My Computer” icon and choose “Properties” or press Windows + Break shortcut key to open “System Properties” screen as shown below:

Click “Hardware” tab


Getting Started Click “Device Manager” to display “Device Manager” page. Find a port like “Silicon Labs CP210x USB to UART Bridge (COM6)”. Here “COM6” is just an example. Different PC may have different COM port.

2.3.2 Communication via Hyper Terminal After the connection with personal computer is made, you could see the following information in Hyper Terminal (Start Menu All Programs Accessories Communications Hyper Terminal).


AVR & PIC DEM 2 Name the new connection in the dialog box. Click “OK” to display setting dialog box as


shown below.

Choose the right port and click “OK” to go into the next page. In related communication port properties dialogue box, choose appropriate Baud Rate. Default Baud Rate is 57600bps (AVRDEM) or 9600bps (PICDEM). Click “OK” button to connect demo board and PC. Then information will be shown in the Hyper Terminal window.

Getting Started In related communication port properties dialogue box, choose appropriate Baud Rate.

PD7 (OC2) on AVRDEM board will be regulated to PWM for speaker port. RC2/CCP2 on PICDEM board will be regulated to PWM for speaker port. PWM width from PD5 (OC1A) (on AVRDEM board) or RC2/CCP2 (on PICDEM board) is to control the LCD contrast. It can be regulated into a DC voltage because of the low pass filter built with U9-LM358 op-amp. Contrast of the LCD module could also be adjusted by screwing R28 adjustable resistance.

4.1 Sample Code for AVRDEM 2 PLUS

All the codes were tested and are proved as workable on the demo board. But please note that all those codes are only for test and research use, we can not guarantee any consequences of inappropriate use of those demo codes. All those demo codes are based on WinAVR (GCC). Sample 1. Light LEDs Associated With PORTA Sample 2. Make the Buzzer Beep Sample 3. Read Temperature from Built-in IIC Temperature Sensor Sample 4. Transmitter Data through the USART of ATMEGA16 S to Display Information with 7-segment LEDs S to Display Information on HD44780 LCD Module Sample 7. LED Mode Code Sample 8. Display data on the LCD Module

4.2 Sample Code for PICDEM 2 PLUS ll those demo codes are based on MPLAB IDE and MCC18 C compiler. ample 1. Light up LEDs Associated with PORTB ample 2. Make the Buzzer Beep
