regarding Eeprom

[durafos]

Hi
I am using flowcode 7.3.0 and i am using PIC18f46k40 ic. This ic number is shown in software but not in supported ic list. so i want to know if we program that ic then it will work or not in long term bases. Because when we start programming that time some logic is not work like analog input, analog out put
And one more problem with us if we are using eeprom then after some time ( after one moth or three to four month ) the eeprom data will automatically change
For Ex. - If we write the value 25 at address 0 then after 3 month it will oo

So please guide what is the correct process to do program from eeprom

Hello,

This is the Flowcode v9 forums, please visit the forums here for v7 related issues.

It might be worth trying the project in Flowcode v9 and seeing if there are any improvements.

I'm not aware of any problems relating to the EEPROM becoming corrupted or lost without being erased.

How often are you writing to the EE memory? there is a limit of between 100,000 and 1,000,000 erase write cycles that can be done on the EEPROM before it will fail and so if you are constantly writing data to a location then eventually it will not work any more. For example if you wrote to an EE address once every second then the EE memory would potentially fail after just over 1 day.

Hi Ben

Thanks for your guidance, Actually you are right some logics are not work in V7 for some ic first we have to select the ic from flowcode recommended list and then start the programming.
And about eeprom , i am not writhing or reading the ee every 1 sec. if i want to write some data then i start the process only for one time. And my program is work for 4 or 5 month but after that the eeprom data is change. but this is not happen with every unit so i am confuse.
