Hi All

 

i have a problem with the usb interface...im running very low on space with the kl25 128Kb part... so no more room to move

and i think that the 26 odd k for the usb may have to go.... but at the moment we are using the cdc ... is hid going to be much smaller....

or are there some o ther tricks that can save me a heap of flash??

 

i have thought oif the possibility of putting some of the data that is in flash into external eeprom but this will have issuse as i have to find lat longs by running through data... its going to take a while at 400kz baud accross i2c

 

anybody got some ideas

 

dan
