Hi, I am about to start a project which will require ethernet connection and I am kindly asking you for some advices on the following topics: 1) On the HW side I will probably go with a LPC213x controller plus an ethernet controller. There is a very interesting, low pin count controller from Microchip (ENC28J60) which is pretty new. Any ex

The 0x4000 bytes of ethernet ram @ 0x7FD00000 can be used for the LCD frame buffer (if it is enough). There is no need to enable the ethernet to access this ram. I have not been able to use the 0x4000 bytes of AHB1 ram @ 0x7FE00000 for the LCD frame buffer. I can read and write to it from the debugger, but the LCD is a no go. It does not seem to matter if the USB is enabled or not. I thought I...
