Recently, many customers are quite interested in the video file we post in our home page. This video file is about a demo program of a car dashboard, which is a basic application of our LCD module. Usually, the display is used for replacing a dashboard in a rally and competitions car. The LCD module shall be able to show the most important parameter of car situation like RPM, speed, fuel pressure, oil pressure and so on. Some customers need a high contrast display for seeing it in every moment of day, even under the sun or in the middle of night. For this application, touch panel is not a must, so we recommend customers to select the LCD module without touch screen because the stability situation will be better.
In fact, it is quite easy to finish the design.
First, make images that will be used for the project. For that demo, our designer made 85 images. The pointers are at different positions on each image.
Second, once the sensor gets data from outside, make the MCU to send command 0x70 to our LCD module to display the corresponding picture. For example, when the speed is 80, make your MCU to display the picture on which the pointer is at 80.
Third, in this way, the dashboard will be automotive as per the data from sensor.
Note: Command 0x70 is to display the picture at specific positon in the flash. The format is AA 70 PIC_ID CC 33 C3 3C.(AA as frame header, 70 as the command for displaying pictures, PIC_ID as the ID of the picture when you save it into the flash, CC 33 C3 3C as the frame end)
Finally, we are in the position to provide technical support. If you have specific requirements, we can help you for the programming on the LCD modules.
