nAssembler

[lkj]

Thank you.

Le programme de grosged n'arrive pas à être compilé par ton utilitaire, et donc, il faudrait peut-être que tu regardes:

Ok, I looked at it. I had to fix a bug with binary literals. Apart from that it was just different syntax and some unsuported abbreviations:
Most notably, there is no automatic substitution of e.g. "MVN r0,0xF000000F" for "MOV r0,0x0FFFFFF0" - it will just give an error that the immediate value cannot be encoded.
Also, for instructions with three operands, the destination cannot be ommitted to be implicitly the same as the second operand. For example no "ADD r0,r0", it needs to be "ADD r0,r0,r0".

Et aussi, rajouter la possibilité de faire bl 826e par exemple, pour appeler directement une adresse, parce que sinon, je ne vois pas comment faire appelle aux fonctions déjà existante, comme afficher des caractères à l'écran

BL 826e is not possible for me to implement: the assembler needs to know the offset, but it cannot know at which address the program will be loaded. You can instead store 0x826e in r0 and then "BLX r0" to get the effect you want.

I uploaded the fixed nAssembler at http://ti-pla.net/a821835.

Well, in theory you could include at the beginning of the generated program a linkage system.

Thank you for update lkj

Thanks a lot for updating nAssembler, lkj

Code: Tout sélectionner

MOV r0,#0xE26F
BL r0

This code doesn't work
An error occurred on BL r0

Yes, you need BLX. BL can only branch to a label (internally an offset from the current PC value). BLX branches to a register-specified destination address.

Oh, sorry, thanks

[grosged]

lkj, do you intend to implement DCW for declaring 16 bit values, and pseudo-instructions like ADR and LDR Rn,=#..?
I wish I could help , but I do know nothing about programming in python.

@gorsged il faut que tu rajoutes le graphisme dans ton tuto sur l'ASM avec l'ARM9 de la Nspire, je fais un peu à l'aveugle, donc, ce serait pratique

"graphismes", c'est en gros taper dans le buffer d'écran au bon endroit, quoi.
Après, tu peux te faire des routines pour rendre les choses plus pratique en fonction de la tâche...
