Hi All,

I was wondering if anyone has plans to port MMBASIC to the Arduino RP2040 connect platform.  Specifically, the Pico's gpio pins don't map the master SPI to the connect's hardware.  Otherwise, it would probably work as it is.

Thanks,
Scott

It looks expensive as well as incompatible :(

That is because they are not using the H/W SPI pins so I assume that Arduino is bitbanging unless the docs are wrong

  Quote  D11 (COPI), D12 (CIPO), D13 (SCK). Use any GPIO for Chip Select (CS).

A LGT 328 is like mega328 but 3.3V logic and twice the clock speed ie 32MHz.
I had thoughts of picomite and lcd as a slave for a uno. Silly but cheaper than a nextion display.

That is a bizarre idea. You know that you can program the Pico using the Arduino IDE? Doing this gives you access to many of the Arduino libraries (GFX etc.)

Of course this doesn't mitigate the fact that the Arduino IDE is c..p compared to any decent development environment (e.g. no debugger)

Many argue that you only need a serial connection for Arduino debugging... but let's be honest... if it's all you have... well...  'nuff said.

It is not so bizarre if you have used a nextion display with an 8bit pic.
A nextion costs more than a picomite and a similar touch/sd card spi display together cost.
com is serial from pic to nextion, ie serprint "line x1,y1,x2,y2".
That is over simplifying but the basic idea.
It was just a thought.

ps. Thinking... 8bit to picomite and 8bit as an addon seems more expected.

The Twain shall meet ... and Sinders does go to the ball :)

Do arduino ide created files work with mmbasic.
I posted about vga ps2 thingy and one arrived and the "Instructables" stuff is supposed to work with another basic but I must use the arduino ide... AAARRGHH!!!
How does it work with mmbasiic or other basic?

The Arduino IDE supports programming the Pico in the Arduino variant of C++ exactly the same as programming a Uno. It would be possible to write a Basic interpreter in Arduino C++ and then program it to the Pico but whether this has been done I have no idea. MMBasic and Arduino are unrelated and MMBasic cannot be compiled on an Arduino.
My point about your suggestion being bizarre is that if you are programming an Arduino Uno to do something and then just using the Pico as a display controller then you are using 2 uP when one (the Pico) could do it all when programmed in Arduino C++ as you have access to most of the Arduino libraries including all the Adafruit graphics libraries and display support

The original post. I misinterpreted. Sorry, I saw Arduino and thought interfacing with picomite.

Hi sir, just loaded arduino ide because want to try vga ps2 thingy and following "instructables"
This is info I got for 8bit use.
The whole idea is strange but got to push the boat out
or it is just using what one knows.

I got the impression that arduino ide code can be used with mmbasic or other 8bit basic. Please clarify if again the twain shall meet.

Only a masochist uses the Arduino IDE. It's truly horrid - and huge.
I'm sure there must be a far better way to program those things.  :(

You are correct. it is and there are.
I lost the plot for vga ps2 thingy.
It's original poster says just use serial tx, rx, gnd
and the "instructables" link. https://www.instructables.com/Using-ESP32VGA32-Terminal-for-Z80-MBC2/
uninstall arduino ide and forget.
