Re: How do I make a port of MicroPython for Casio calculators?

Yeah, I knew about this port - in fact Casio not releasing MPy for monochrome calcs is why I'm doing this port myself :p

Shame they used the big font though, you could fit much more letters in the screen.

Re: How do I make a port of MicroPython for Casio calculators?

I refactored that because it was a simple way to automatically send the string "from xxx import *" to the shell. So pyexec_friendly_repl(char *text), through a bunch of ifs, ultimately calls int readline(vstr_t *line, const char *prompt, char *text), which is the following function: int readline_ind...

Re: How do I make a port of MicroPython for Casio calculators?

No, it's the string "from xxx import *": char str[30]; char filename[13]; strcpy(filename, _sFile); filename[strlen(filename)-3] = '\0'; sprintf(str, "from %s import *\r", filename); for (int k = 0; str[k]; k++) { str[k] = tolower2(str[k]); } _iAppMode = SHELL; mpy_main(str); The actual text of the ...

Re: How do I make a port of MicroPython for Casio calculators?

There you go: int mpy_main(char *text) { mp_stack_set_limit(256); int heapLen = 32768; #if MICROPY_ENABLE_GC heap = malloc(heapLen); #endif if (heap == NULL) { int key; locate(1,1); Print("Couldn't alloc!"); GetKey(&key); } ML_clear_vram(); ML_display_vram(); shell_init(); readline_index = 0; initNb...

Re: How do I make a port of MicroPython for Casio calculators?

Calling mp_stack_set_limit(2048) at the beginning of mpy_main() doesn't seem to fix the "infinite loop" problem (I also tried with 256). Doing "reset&run execution" on the SDK gives the error "reserved instruction exception by code read access at 003317F8" which is the function nlr_jump_fail: 003317...

Re: How do I make a port of MicroPython for Casio calculators?

I can't use the mp_pystack_init() function though, as I can't know the absolute stack addresses (unless there's another way, but whatever, it seems there's only 3k of stack available, not gonna bother when I've got 32kb :p). Do you have any idea for my other problems (raising a keyboardinterrupt fro...

Re: How do I make a port of MicroPython for Casio calculators?

Thanks; I must have missed that #define when I skimmed over the mpconfig.h. I also thought MPy used the allocated memory as stack memory, instead of using actual stack memory. However, for some reason defining MICROPY_STACK_CHECK makes me unable to import any script; the shell simply hangs as if it ...

Re: How do I make a port of MicroPython for Casio calculators?

I can't really do without recursion though (in algorithms class, recursive functions are almost always studied). Sure, recursion eats memory, however MPy handles regular out-of-memory just fine: l = [] while True: l.append("12345678") https://i.imgur.com/EQ6DEc7.png Also, if the error is caused by b...

Re: How do I make a port of MicroPython for Casio calculators?

Hi, Unfortunately I have 2 more problems with Micropython. The first one is that, for some reason, my app crashes when I call a recursive function with too much depth. For example, this simple recursive function: def r(n): if n == 0: return 0 else: return 1+r(n-1) Calling up to r(63) works fine, but...
