RE: 50g sd card funciton
Not sure what your question is. There is no such instruction in the HP 50g.

RE: 50g sd card funciton
... maybe this https://support.hp.com/us-en/product/hp-.../c01974483 from the learning modules.

ACCESSSD is one of the additional "Saturnator" opcodes that are available to Saturn assembly language programmers when targeting one of the ARM-based RPL calculators. IIRC, a selector needs to be loaded into the P register before issuing that opcode, but I've never seen any official documentation for the various options it recognizes. There's a couple of references to it in the 50g AUR, and several posts in the comp.sys.hp48 newsgroup, but I'm afraid none of that really shows what all the options are. If there's any published documentation for it, I've never been able to find it in the usual places. If Claudio L. happens to see this post, perhaps he can share what he knows about the various parameters for ACCESSSD since I'm pretty sure he spent some time digging around to uncover some of its secrets in the past. |

RE: 50g sd card funciton
Hello,
I tried to have a look in the emulator, but the data is spread out in a lot of places :-( I however found this of interest... And emu48 might be better commented and organized. But at least this should give you a head start to dig deeper. const NativeCodeFunctionPointer NativeCodeFunctions[MAX_NATIVE_CODES] = { // 0x00 native_loop, // 80B 00 native_flagprep, // 80B 10 native_testflag, // 80B 20 native_false, // 80B 30 native_dofalse, // 80B 40 native_makebeep, // 80B 50 native_movedown, // 80B 60 native_moveup, // 80B 70 native_createtemp, // 80B 80 native_RCKBp, // 80B 90 native_keydn, // 80B A0 native_goslow, // 80B B0 DN,DN,DN,DN, // 0x10 native_poweroff, // 80B 01 native_gettime, // 80B 11 native_settime, // 80B 21 native_reset, // 80B 31 native_selftest, // 80B 41 native_isnative, // 80B 51 DN, // 80B 61 native_getserial, // 80B 71 DN, // 80B 81 DN,DN,DN,DN,DN,DN,DN, // 0x20 DN,DN,DN,DN,DN,DN,DN,DN, native_hst1, // 80B 82 native_Hscreensize, // 80B 92 native_Wscreensize, // 80B A2 native_IsMidApple, // 80B B2 native_IsBigApple, // 80B C2 native_SetKeyboardBufferService, // 80B D2 native_IsAppleV2, // 80B E2 native_SetKeyTime, // 80B F2 // 0x30 native_config_disp0, // 80B 03 native_unconfig_disp0, // 80B 13 native_refresh_disp0, // 80B 23 native_set_lines_disp0, // 80B 33 native_set_offset_disp0, // 80B 43 native_get_lines_disp0, // 80B 53 DN,DN, native_testhst1, // 80B 83x DN,DN,DN,DN,DN,DN,DN, // 0x40 native_BBReconfModules, // 80B 04 native_FREraseBank, // 80B 14 native_FRWriteBytes, // 80B 24 native_FRFormatBank, // 80B 34 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0x50 native_remoteon, // 80B 05 native_remoteoff,// 80B 15 DN, // 80B 25 DN, // 80B 35 DN, // 80B 45 DN, // 80B 55 native_outbyt, // 80B 65 DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0x60 native_access_sd, // 80B 06 native_valid_port_tag, // 80B 16 native_RclAssembly, // 80B 26 native_ScanEveryObject, // 80B 36 native_CheckSD, // 80B 46 native_CheckSDProtect, // 80B 56 native_FormatSD, // 80B 66 DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0x70 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, native_setfield, // 0x80 native_mov, // 80B 08 native_add, // 80B 18 native_sub, // 80B 28 native_mult, // 80B 38 native_div, // 80B 48 native_mod, // 80B 58 native_not, // 80B 68 native_neg, // 80B 78 native_left, // 80B 88 native_right,// 80B 98 native_xor, // 80B A8 DN,DN,DN,DN,DN, // 0x90 native_SaltireCode,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0xA0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0xB0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0xC0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0xD0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, // 0xE0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, native_cacheflush, // 80B EE native_armcallsys, // 80B FE // 0xF0 DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN,DN, native_armcall // 80B FF }; Although I work for the HP calculator group, the views and opinions I post here are my own.

I'll look in the only place I could've kept hand-written notes about it: My copy of the James Donelly book which has some notes in it from my Saturn coding days. I remember the P register would select a sub-function, but they were nothing particularly useful. If you need access to the SD card from RPL, I'd say use the SDLIB that comes with the SD Filer. It has more complete SD card access than the virtual saturn opcode. |

Thanks in advance for anything you're able to share. I'm also particularly looking forward to experimenting with some of the previously-unknown (to me) opcodes listed in Cyrille's header file above. Unfortunately I have little bandwidth for calculator experiments right now... |
