Upon initialization, the default actions for the GLCD are:ġ.) A short reset to the GLCD and Cursor and blinking cursor is disabled. Please take note that the backlight connections are not included here too.Ĭall the function above to start the GLCD. The connection is shown in this following diagram: On top of that, the controller allows users to switch between the text and graphics mode.Īs usual, include the skpic32-glcd.h and the graphics.h files into your project, like this:Ĭonnect the data pins (DB4-7), E, RS and RST individually as shown in the picture. There is a serial mode but it will be covered in another tutorial. To conserve pins, only 4 data pins are used, hence the 4-bit mode selected in the controller during initialization. The advantage of this controller is it can display Mandarin text apart from the Latin alphabets with only a few instructions to the display. One of the GLCD we are using in this tutorial is the ST7920-type controller. To display graphics and text output from the PIC32, we need a Graphics LCD (GLCD). ![]()
