Re: PicoMite V5.07.00: MMBasic on the Raspberry Pi Pico

the 80+ column problem I'm seeing is that I can't edit a line that's longer than the screen display is wide. It doesn't scroll or display correctly on the 80-column wide terminal windows I prefer to use. I'm afraid the editor doesn't support editing a line greater than the display screen width othe...

Re: PicoMite V5.07.00: MMBasic on the Raspberry Pi Pico

I have one of those cheap displays with a SD slot on the back, as per the manual, I'll look at soldering on some connections & getting it going. Might need a bit of prodding as to exactly how to save and load a program to it, I've read the manual around this, but am not completely clear. Update...

Re: PicoMite V5.07.00: MMBasic on the Raspberry Pi Pico

Another question, is there any way of saving a copy of my program somewhere else, other than in flash Setting up an SD card is fairly easy with MMBasic, and I'd recommend it. Even the cheap solution of header pins soldered to an SD to microSD adapter works well. Some SD card ports (like the ones on...

Re: Bit Bang 4 ws2812 strips

There are large periods of time when the PIO will be doing nothing. Once you send your first stream of data, to your LEDs you will pause for say 0.1sec during this time, instead of pausing, you reallocate the pin the PIO is driving & send another stream of data to your second string of LEDs and ...

Hi Hermann, Are you able to get RLE compression working on your Pi compiled DSView. When I turn it on the drop down for the sample period actually gets less, on the version I have on my PC it gets significantly longer? For example sampling a single channel:- with RLE enabled, 50MHz sample rate I can...

I have not tracked previous post on the topic.

Hi Hermman,
Did you ever find a way of running overclocked, from the flash memory, rather then loading into ram; by reducing the flash clock rate possibly?
I'll give you test program a go later.
