Too many instructions

[carltonb]

I've been trying to do a osciloscope with pic 18f4550 and a GLCD module.

i've managed to get pretty far, but i'm having problems with what seems to be too many instructions.

Isolated all my instructions work pretty fine, but when i add some or all of them togheter it simply does not work.

anyone has any idea of what could be happening?

Please post the complete code so that the cause for the problem can be found.

While(1) loop is missing.

[carltonb]

tempo is always !=0.
i had it as while(1) before, same problem.

Zip and post the complete mikroC project files.

[petar.timotijevic]

Hello,

Please Zip and attach in new post latest version of project files.

[carltonb]

attached file.

@carltonb

The code compiled successfully for me. I didn't check your ADCONx settings. ADC result is 10-bit and you have to replace

Code: Select all

dado[var]=((adresh));

by

Code: Select all

dado[var]=(adresh << 8) | adresl;   // if ADC result is right justified.

Zip and post the code which gives "too many initializers" error.

You get that "too many initializers" error if you try something like this.

Code: Select all

unsigned char test[4] = "Hello";   //Hello + '\0' = 6 characters, doesn't fit in 4 bytes

[carltonb]

Its not an error of "too many identifiers".
Its not a compiling error at all, its just an error at the device itself.
The instructions are only played "half-way" or not at all depending on how many instructions i add to the program.

i have a few pic18f4550 and tested if it was a chip problem but it is not.

[carltonb]

whenever i get this problem, i noticed that in the hex only has on position 0000 D7FF.
everything else is FFFF.

Hello,

What version of compiler you have?

Compiler have proper license?

Try HEX file from attachment.

1. 80% you have the license problem ! if you are not registered, register it properly.
2. why you didn't use my oscop project ? petar.timotijevic has told you ! you can see a lot !
3. you better not to use all library's together. its not cool ! think first, then read manual if needed, then choose.
4. you cant use dot for showing on glcd. i had this problem too. its better if you use line instead of dot.
5. i put your code in Proteus with a little changes. check it out and see it is working ! but not very cool ! it needs work.
good luck .
best regards, Josef.
