Yes, I believe Lucio is happy to see such results from "his worldwide students". Brilliant (Geoff)MMBasic into a brilliant (Olimex)board. Sounds like a good team to me (with a happy teacher). Nice photos from the event. I would like to see next time a short movie as mikroe did. Vasi Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang

Not a ton of code, just an exceptionally brilliant idea incorporated in 50 or so lines. Without that idea the MM would not have had video. Geoff Geoff Graham - http://geoffg.net

I explain, wich 'brilliant idea' of Lucio Di Jasio is under MMbasic?

The method used is based on a technique described by Lucio Di Jasio in his book "Programming 32 bit microcontrollers in C”. It uses a DMA (Direct Memory Access) controller to transfer the pixel data from memory to an SPI (Serial Peripheral Interface) controller which then clocks out the video with the required timing. The output is sharp and rock solid, you could not get better even if you were using a dedicated VGA controller. Other than servicing an interrupt this method entirely bypasses the PIC32 CPU which only has to write the pixel data to a defined part of memory and it will then magically appear on the video monitor. This leaves the CPU free to run at full speed interpreting the user’s BASIC program. Geoff Graham - http://geoffg.net
