Problem with 24lc08

[Guest]

There is next code:

[ECACE]

Can we see the code you use for reading it back?

Also, do you mead that HT sends a series of chars, not a string?

It takes 5 ms per byte to write to the eeprom. At 9600 baud, you can
receive one character in about 1 ms. You will miss incoming characters
if you write each one inside the #int_rda routine. (Apparently Proteus
doesn't simulate this behavior exactly. It appears to use a shorter time
than 5 ms for the eeprom write).

Wait until you get the complete message from the PC. Use the Ex_Sisr.c
example file to setup a circular buffer. In your main(), create a loop to
check if characters are in the buffer by calling bkhbit(). If chars are
available, get them by calling bgetc(). Put them in another array.
When you get the '\n' character, then you know you have received the
complete message. Now you can write the array to eeprom.
(If it's a very large message, you could use Page Mode for the eeprom
to decrease the writing time). But hopefully, you will not receive another
message while you are writing to eeprom. If so, all or part of it will be
lost.

Also, add the ERRORS parameter to the #use rs232() statement. If you
do miss characters due to them coming in while an eeprom write is in
progress, the ERRORS parameter will prevent the UART from locking up.

Thank you.
