Troubled with Instant Ints and TMR2

[Josuetas]

Doh!
Doh!
Doh!
A whole day looking a that

Darrel this is the next question (i havent even look through it), now i have an array of 15 bytes, but i see it has a pointer EXT, is there a way to point to each Bit of this array? i am going to do some math to each bit now and this would be useful.

Something else, this project is short in code Space since i only have 2k of my 628A (no16F88 around here) removing ReEnter could save me 150 instructions? the fact is this piece of code is like 780 words already and i havent done anything :P.

Anyway tomorrow i´ll do the short math, i´ll begin to cry when the word count reaches 1800.

...is there a way to point to each Bit of this array?

Melanie has provided the answer. See 3. How can I reference a BIT in a BYTE ARRAY? in her very helpful Bits, Bytes Words and Arrays Post.

Thanks again Melanie.

[Josuetas]

Thanks Steve i will be using it.

On the other hand.

Its the post about the EXT modifier, i have been using it as a label to create tables in codespace in the past, BUT: right now i am using 628A wich doesn´t support READCODE instruction, can i still use it to create a table in codespace? if so (i guess i can) how can i read it?. It is a 14 bits x 120 Word, since the device is 14 bit i guess i could store each word in a memory space? kind of like the code to store strings in codespace? I havent been able to use the last one since i dont know how the data would be stored as Words and not as strings. Again ignorant about asm.

This is my table

There's still the 128 Byte EEPROM on board option... but it's way too limited.

LOOKUP(2)?

External EEPROM?

[Josuetas]

Eproom will store the strings of my LCD, and i would need 256 Bytes to store this table in Eproom vs the posible 120 "SemiWords" of codeSpace.

Thanks for your concern

And.. no external component.. i am looking for a low budget device here, also low Real State.

[Archangel]

Doh!
Doh!
Doh!
A whole day looking a that

Darrel this is the next question (i havent even look through it), now i have an array of 15 bytes, but i see it has a pointer EXT, is there a way to point to each Bit of this array? i am going to do some math to each bit now and this would be useful.

Something else, this project is short in code Space since i only have 2k of my 628A (no16F88 around here) removing ReEnter could save me 150 instructions? the fact is this piece of code is like 780 words already and i havent done anything :P.

Anyway tomorrow i´ll do the short math, i´ll begin to cry when the word count reaches 1800.

Hi Josuetas,
16F648A is the same chip with 2X the codespace and similar price, uses same data sheet too, but you get 4K instead of 2K.
JS

[Josuetas]

You cant imagine how nice it would be for me to find one around here!

The fact is that 648A is sold out, today i went looking for it with no success.

Not finding supplies around here really makes me sad.

So it seems i will have to upgrade the uC to something like 876A, easily found here. Though more expensive. Its sad because 876A is not improving anything for me, maybe just the speed, but even there i will have to use an external OSC ($$).

What i really need here is 16F88, int OSC 8 Mhz always better than 4 Mhz and 4K memory should be enough.

I am from Colombia South America by the way... wanna switch?


Leaving this discussion Aside... i am not done with 628A you know? i havent reached 1800 words (where i will cry) right now i just need to store the table in code space... do you know the way? the solutions about this given in the forum use READCODE wich 628A cant execute.

[Archangel]

Aside from lack of PICs, oh and that thing about the cartels . . .I hear Colombia has many nice things, great coffee, emeralds, cattle ranches, I knew a girl from there who went back and became Miss Colombia, and she was cute too !, but no I am too old to make that big of a change. I did not know from where you are hailing, will U S Suppliers not ship to Colombia? I do not know of any techknowlegy restrictions regarding shipping to your Country, You might check with www.Mouser.com

[Josuetas]

No complains... it would take like two weeks for that pic to arrive here, and would cost me around 45 dolars (Shipping). Its not that i cant find pics here... there are just not all the ones i want.. switching to 876 its possible but... we are forgetting the real problem... nOT THE PIC!!... i need to store and retrieve that table!!! it has to be pretty simple.. REMEMBER 628 still has free code space.

By the way every one seems to know someone from Colombia... i´ve had more foreign Girlfriends than girls from here.. although yes YES... women here are hot hot. I was kidding about switching i´ve been to many places and i wouldnt.... but the invite is still on the table you MUST visit us ... someday...
