Hey there! I'm just wondering, is it possible to display the unix time in Gmenu2x and not the time, how long the handheld is on? Is there a setting for it somewhere?
It was an example, there are many RTC modules available. If you want to use UART it exists also.@TeDaDeS thats actually the problem - the CPU is capable of I²C, but there are no drivers for it, at least i could'nt find any. And i'm not that good at c coding, that i could write one by myself and that leads me to the second problem
@Orkie to solder an rtc module to the cpu directly would be a much more ellegant solution, but i'm just not capable of doing that and i'm too afraid to damage my unit.
My solution may be not the accurate one, but in my opinion it's the safest way to add anything. I thoughd already about it, just to make some kind of external attachement via the EXT connection, but there should be more, than just an RTC to justify an external device. Maybe i should draw it to show my thoughts in a better way
I could imagine RTC was designed into the product at one point but wasn't important enough compared to battery life or cost. So it was removed again.I've never heard of anybody doing it, I'm not sure anybody has ever been desperate for an RTC before. I2C is definitely exposed though, the serial number and LCD settings are stored on an I2C EERPOM - you could probably daisy chain something off that (might need a buffer): http://wiki.gp2x.org/articles/i/2/c/I2C.html
