Do I need the RP2350 Now?

PicoCalc

I’m just about finish with my MMBasic spreadsheet app. However, this morning while I was testing the app I got “ERROR: out of heap memory”. Does this mean I need to upgrade to the RP2350 board now? If so, which RP2350 board do I need? There seems to be RP2350a, RP2350b, . . . etc. Also, in order to guide me to the right board, you need to know that I use my PicoCalc solely for writing Basic programs. Does the RP2350 come with MMBasic? Or are there other boards that I should consider? It seems that I only need more memory. Of course, the added speed of the RP2350 would be welcomed. Thank you for you advice. - Jim

I have a Pimoroni Pico2 in both my PicoCalcs. They’re fast and have the added 6MB PSRAM where arrays are stored in MMBasic. Try dimensioning an 850x850 array in a normal PicoCalc! Yes, you’ll get more heap but even so, analyze your code and see if you can reduce nested loops, recursive calls and other heap-robbing code.

Another vote for the Pimoroni Pimoroni Pico Plus 2

I couldn’t live without the ability to overclock to 378Mhz +. Sticking with my Pico2…, hopefully Pico3 one day

I set CPUSPEED to 384000 with the Pimoroni Pico 2 and have PSRAM active. No issues at all.
