Hi
wrote to eeprom each day at midnight
read from eeprom. Each time there came rain and at midnight
and read from eeprom if i check the past 30 days

on the 16f1509 i will read/ write at midnight
and when selecting one of the 30 past days
amount of rain will only be saved each day at midnight

Again what does this mean? The 16f1509 does not have EEPROM.

How many times do we need to ask that you express complete thoughts in a full sentence (sentences start with a capital letter end with a period and usually contain a verb and an object.) ? And there is nothing wrong with your English. It is not bad at all. You have plenty of posts in this thread where you were very understandable. You can make yourself understood when you try.

What are your current coding attempts regarding flash read/write

 

What are your current coding attempts regarding flash read/write

Have deleted it all, and were waitning on u guys.
have nothing in code to read write flash.
only the allocation line

Ok,, now i will have the "data" from Flash, read into 29 var. called rain_data(1) until rain_data(29) or am i wrong ?
then i can make the "selcetion" of days.
But that will next year

Today i have been improved the accrasy of the temprature.
making it read every second for 3 sec., and got the average, and compared it to "now" reading, and if not more than 0.5 degrees difference, it will show temprature, if not, it will do another round.

HAPPY NEW YEAR.

That I did not quite understand? But let us take that next year

Sorry , my mistake,
i mean that the code you posted, Flash_read and prepare_for_flash_read
should be enough to read out from flash, but have no data in it yet.

Still i need to figure out something with bad reading from AN0.
When i have 4 reading in a row with same result +-2,5 degree.
and that one i way off, it shouldnt register as ok. but that something i have to work with
