|
||||
2014-05-14: Fully implemented. There is still a bug in in the LCD
|
||||
communications. The LCD ID is read as 0x0000 instead of 0x9325.
|
||||
|
||||
2014-8-19: Updated. The LCD ID is bad because the on-board LCD is
|
||||
*not* an ILI9325. It is an ILI9341. The ID lies in a different
|
||||
address and is 0x00009341. Need to write a new driver.
|
||||
|
||||
The LCD backlight appears to be functional.
