MAX7219 With 8x8 LED matrix x4 (Oshonsoft Basic Compliler).

For years, I have wanted to experiment with LED matrices, and I finally found the time to do it. I wrote a small test program that displays the well-known and popular message "Hello World!" scrolling from right to left on the LED banner.

I am including the test program and the library I wrote. The library uses the internal MSSP module of the PIC, operating in SPI master mode with a clock speed of 4MHz (internal clock 64Mhz).

I have updated the files, just simplified some functions (2024/06/02).

Thanks T.
I have several similar screens running with C, but I haven't had time for oshonsoft yet, let's see if during the June holidays I can get them up and running, first some that have I2C, then others through SPI and finally the touch ones.

Hi D,
It will be quite a while before I need TFT screens, as my project takes me ages to move forward. When I started my project I chose SPI over I2C, so I bought all of my peripherals, with SPI, I've had some SPI TFT screens for a couple of years so far.

Most TFT screens are SPI anyway, the only I2C screens I've seen are the tiny 0.96 inch OLED ones.
