problem solved, the memory had a problem

thanks to all of you for your help

thank you for your response Jay

I put 5V on the card, and then a regulator is powering the PIC, on that part everything is ok.

There is a big problem, when I write in the memory and then I try t ...

Thank you, I took off the address port part.

the fact is that it still does not work...

Do you think my write/read functions are correct?

Thanks

Hello,

I write those #use FAST IO:
#use FAST_IO(D)
#use FAST_IO(G)
#use FAST_IO(H)
#use FAST_IO(J)

I did not know if it was necessary for the address ports so I tried with and without, I hav ...

Hi everyone,

I am trying to write and read inside a memory cypress 62167 with a PIC18F85J90. Here is my programs for read and write in the memory and the port configurations, i precise that the I/O ...

Hello,
Thank for your response

1) I do not use fast I/O, I have just took off the part interupt for the serial ports and how I fill the random table (which is not important for my problem).

2) ...

Thank you Ttelmah, you were right the datasheet explained everything.

But there is still something that I cannot explain and I need some help to understand:

When I write this code:

#FUSES HS ...

hello RF_Developer

Thank you for your response.

I would like to be sure, the PIC 18F85J90 can run at the 40MHZ maximum?or can I run it to 80MHZ (4x20MHZ) with a PLL?

Thank you

Hello,
I am trying to make a PLL with a PIC 18f85J90 with a high speed oscillator (quartz at 20MHZ), here is my code:

#include<18f85J90.h>
#device adc=16
#FUSES HS //high speed clock
# ...
