Hi
I have a project where a Microcontroller (Atmel mega162) controls the switching on/off times of a motor/heater.
I would now like to make a data logger that will store the date and time of day that the switching occurs.
I would also like to be able to extract the data from the control board with out having to connect it to my PC.
I imagine i can do all the data logging in my microcontroller by storing each event to 4x8bit EEPROM addresses at as the time of day and day are supplied to the controller via a RTC chip.
The problem now is how do i get it from the board?
Ive looked into finding a USB driver that will change the seriel EEPROM data into something a USB pen drive can receive but with out a master controller this doesnt seem to be a suitable option.
I was then thinking about looking for some sort of bluetooth chip that might transfer the data to a mobile phone.
Does either of these options sound like they might work or has any one come across a similar problem?
