... Design and Production Services Embedded Artists provide design services for custom designs, either completely new or modification to existing boards. Specific peripherals and I/O can be added easily to different designs, for example, communication interfaces, specific analog or digital I/O, and power supplies. Embedded Artists has a broad, and long, experience in designing industrial electronics in general and with NXP’s LPC1000/2000/3000/4000 microcontroller families in specific. Our competence also includes wireless and wired communication for embedded systems. For example IEEE802.11b/g (WLAN), Bluetooth™ ...

... This is at least true for NXP’s LPC-family of processors with integrated LCD controller. Instead of having 2 bytes per pixel (for 16- and 12-bit color depth) 4 bytes are needed per pixel. ...

... A +5V, 2A external power supply is recommended since it then can be used for other LCD boards also. 3.3.2 Power consumption of 7.0 inch LCD (EA-LCD-006) When using the 7.0 inch LCD together with the LPC1788 Developer’s Kit (LPC1788 OEM board plus OEM Base board) the current consumption on the +5V (external or USB powering) is about 1400 mA. ...

... There is a 40MHz oscillator that can generate a pixel clock to the LPC LCD controller. This shall currently not be used since 40MHz will create a higher memory bus load than most designs can handle. The frequency will be changed to 33.333MHz in later revisions of the boards. The oscillator is normally only mounted on 7 inch LCD Board. Copyright 2012 © ...

... LCD Board - User’s Guide 4.4 Software Driver A general software driver has been created to in order to make it simple and non-complex to work with different LCD:s. This section contains a very brief description of the structure. The code is the general documentation in itself, simply because the software will likely be updated The software driver package (a zip-file) is downloaded from Embedded Artists support page for the LCD Board ...

... Note about 7.0 inch LCD (EA-LCD-006 recommended to generate the highest possible internal pixel clock from the LPC LCD controller. According to the datasheet a minimum clock frequency of 32.4MHz is needed, but 30MHz will work just fine. Do not use the on-board 40MHz oscillator (on rev A of the LCD Board) to generate the pixel clock ...
