Hello Benjamin, The Direct Drive LCD has issue when it uses the ExDMAC controller to pump the TFT-LCD, that is hogs the external bus and holds off the CPU. In the DD-LCD application, it treats the external bus as a "shared resource" and controls access to the bus through RTOS functions / task scheduling (uses a list to know who will be using the resource basically). You might take a look at this applications for some ideas. Sorry I cannot give you just "cut and dry" answer. -Kevin
