However, to create animation on this display, you would need to use what you've already described in your question, which is a double buffer. This will effectively clear that area of the display and you can draw the new contents over. Just fill the area you want to draw with a color that is the same as the background color.

For the PIC initialization (refer to function initIO() in main.c), nothing really special to take note of, except to set the correct TRIS bit to assign the input/output pins.įor simple clearing of the screen and drawing new text/graphics over, you can use ST7735_fillRect function, provided in my library.

It is using software SPI for this LCD (but can be switched to hardware SPI easily).

The source code features a terminal via UART which allows you to read a 128×160 24-bit bitmap from the SD card slot and display it on the LCD. You may find the entire source code for this LCD (and other interesting modules you can play with) here designed for the PIC24FJ64GA002 but can be ported to other PIC too. In my experience using the latch to write to the port is always better to avoid read-modify-write issues. You can also try between the PORTA/PORTB registers and the LATA/LATB registers and check if there's any different when using the source code provided by that website. As this is optional, both codes should work on your LCD. The code on the website you sent me is very similar to my codes, except that the author does not set the gamma control (ST7735_GMCTRP1) of the LCD during initialization. If you're using the PICKit for programming, make sure that none of the pins you use for this LCD conflicts with the pins used for the PICKit – that will cause problems. This ensures that the LCD can receive the proper initialization data. The same applies for other output pins too, make sure that you can set their states from codes. RA6 is a special pin on this PIC, so your configuration bits (_CONFIG() declaration at the beginning of your code) will needs to be set properly to allow using it as output. At minimum, set TRISA = 0x00 and TRISB = 0x00 for all output pins, and remove SDO1SEL because you're going to use software SPI (as in the code you sent me) and not hardware SPI. RA6 a shared pin on the PIC16F1827 so you'll need to set some registers to enable digital input on that pin. In particular, make sure that you are able to control LATAbits.LATA6 freely from code. In fact it is a good practice to make sure all output pins you intend to use can be freely controlled from code and all input pins can recognize digital 0 and digital 1 properly before attempting to connect any devices to the PIC. 100ms) in between and see if you can observe a square wave on your oscilloscope, or 2.5V on your multimeter if you do not own an oscilloscope, on each of the output pins. LATBbits.LATB1, LATAbits.LATA6) with sufficient delay (e.g. You can first try to write a simple program with a while(1) loop to toggle the pins assigned for this LCD (e.g.
