I really don't know yet how much work it would be to port STMBL to the Pico. A stock STMBL drive, with an STM32F405VG processor has four analog inputs (as far as I can tell). Those are 12bit, and can be scaled in stmbl's local hal. I haven't investigated the sampling rate for those conversions. The STM32F4xx processors have a lot more analog inputs available, but teasing out which ones don't conflict with needed digital i/o, and how to route them inside the stmbl code is more than I've done. The Pico pinout seems to indicate only 3 analog inputs.

What comparison can be made between the very limited, fixed scale A-D conversion of a mesa card's 1st 4 inputs on say a 7i76, and the A/D speed and scaling that $4 pico-pi might be able to do when running the STMBL code, and how fast could it do it? Having those figures at hand would determine just how usefull the pico-pi might be. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
