* The LCD module gets its reset from NRST. As explained previously, this NRST is
|
||||
* shared with the JTAG port and the push button BP1. The LCD chip select signal is
|
||||
* connected to NCS2 (a dedicated jumper can disable it, making NCS2 available for
|
||||
* other custom usage).
|
||||
*
|
||||
* The SAM3U4E communicates with the LCD through PIOB where a 16-bit parallel
|
||||
* “8080-like” protocol data bus has to be implemented by software.
|
||||
*
|
||||
* LCD backlight is made of 4 white chip LEDs in parallel, driven by an AAT3194
|
||||
* charge pump, MN4. The AAT3194 is controlled by the SAM3U4E through a single line
|
||||
* Simple Serial Control (S2Cwire) interface, which permits to enable, disable, and
|
||||
* set the LED drive current (LED brightness control) from a 32-level logarithmic
|
||||
* scale. Four resistors R93/R94/R95/R96 are implemented for optional current
|
||||
* limitation.
|
||||
*
|
||||
* The LCD module integrates a 4-wire touch screen panel controlled by
|
||||
* MN5, ADS7843, which is a slave device on the SAM3U4E SPI bus. The ADS7843 touch
|
||||
* ADC auxiliary inputs IN3/IN4 are connected to test points for optional function
|
||||
* extension.
