Daftar Isi:
- Several researchs of interface between CMUcam3 and LCD Graphic SONY ACX705AKM say that the problem occured is how to display the captured image by CMUcam3 to LCD SONY ACX705AKM. Based on the problem, has been built a controler supporting communication between CMUcam3 and LCD SONY ACX750AKM. An color conversion method (Color Bit Depth Reducer) is needed to reduce the color depth, so the image can be displayed on LCD SONY ACX750AKM. This controller is using processor, IC TTL74LS08, and several power supplies to supply power to processor, IC TTL74LS08, CMUcam3, and LCD Graphic SONY ACX705AKM. The processor, Microcontroller AVR ATMEGA8L, is programmed in assembly language for controling the syncronizing-signal on LCD SONY ACX705AKM and also harmonizing the work of CMUcam3 and LCD SONY ACX705AKM by the interuption signal sent by CMUcam3. CMUcam3 is programmed in C to capture and convert the 24-bit image into 9-bit image by Color Bit Depth Reducer method. A Pixel is sent by CMUcam3 to LCD SONY ACX705AKM using an interuption rised by a signal from controller to CMUcam3. The interface sistem is tested by a built-controller, is shows that the MCK frequency is at 16 kHz � 98 kHz and the image is displayed correctly on screen of LCD Graphic SONY ACX705AKM. The optimal MCK frequency is 98 kHz with Hsync frequency on SONY ACX705AKM is 358.68 Hz and Vsync frequency is 1.79 Hz. Microcontroler AVR ATmega8L can be plotted as clock source for LCD SONY ACX705AKM using Timer2.
