I am fairly new to programming and have quite a task at hand to semi backward engineer a device with the above chip at its core.
Sofar I have managed to get the SPI to comunicate but now find i need to attach an LCD to the I2C bus. I have to use this bus as nearly all other ports have been used for other functions.
Understanding the I2C is a struggle but have used it with the Arduino quite happly but I am struggling to get my head around the concept on the AT90CAN to drive an LCD. Its the libraries that are fighting me!
I have searched this forum and used google extensivly comming up with next to nothing. Could anyone please give me a general pointer to any how-to's or tutorials that may give me a hand in making progress.
The tools I am using are AS6.1 with an AVR dragon while the dev board for testing is the DVK90CAN1.
I dont normally like to ask but i feel i am banging my head on the wall! learning curve is steep!
Any help would be appreciated.
