I dont know what version of firmware you have but what you propose wont work. The program wont take in more than 255 for the delay because its only working within a single byte.

You will need to add code such that it will loop a much longer delay. Or make a delay that take in 2 bytes values up to 65535 delay value.

Im sure theres a modified ITPS firmware that do this, ask around

i search the forum before and the only was i found is from brooksware2000 that he will post a programm this was at june
Or a Power ON/OFF Programm from you

My problem is i have no programming knowlage to programming the ITPS complete new with a loop.

When there is a FW that has a longer shutdown sequence please sent me the HEX file.

P.S. my Firmware what i use was the FW from itps3.zip

I cant remember the name of the user who got hold of the modified firmware from the ITPS company.

The firmware is supposed to have a longer time delay.

Start a thread or something...or else mail the ITPS guy for the longer delay version of their firmware. Im 99% it does exist

I wrote to sipport@mini-box.com i found no other adress

Hi,

i progged with RedZac from another forum a modified fw over a variable there is a shutdown time from 1min to ..... min

What forum was that? Any more details?

Hi,

this forum http://www.car-pc.info/phpBB2/viewforum.php?f=5

when you need the programm, please send me a pn with your email and i sent you this programm,

i dont know of right it alowed to put the fw on the forum ?

The FW has a new variable for min shut down easy way for all times 1 min to xx

Thanks, unfortunately my German is a little rusty

I also dont know about the legality of posting the firmware; but others have posted firmwares before... Anyway, i sent you a PM...

OK here is the source
