Here is the link to my board. Including CAD files (Designspark), gerber,=20 GCPrevue and PDF files, BOM list and software. The software is based on Microchips TCPIP Demo Application from the MLA. It= =20 also has a USB Host MSD task and some other tasks for the radio. It include= s a=20 bootloader, which loads a hex file either from a flash drive or via a USB H= ID=20 interface (based on AN1388). Don't use the HID bootloader with an applicati= on=20 which is a USB host since it will output power on the USB power lines on th= e=20 device connector when the application starts after a bootload. It is saved as a stand alone project for MPLABX and XC32 V1.20 or later. Al= l=20 needed files are included and there is no dependency to other files. Filnam= es=20 are referenced with relative paths so it should be compileable from anywher= e.=20 You will need the MPFS2 tool from the Morcochip TCPIP stack to convert and= =20 download files for the web server to the external flash. The software is not as well written or maintainable as I would like :-) (an= d=20 there even are a couple of GOTOs). The header file which has information about the hardware configuration=20 (HardwareProfile.h) is done in the same way as most MLA project so this can= =20 relatively easy be used to make new build configurations for the Microchip= =20 demos (for the TCPIP stack for example). /Ruben >=20 > > According to Ruben Jnsson on Tue, 04/15/14 at > > 02:27: > > >=20 > > > Give me a couple of days and I will put up a link for downloading the > board > > and=20 > > > sw files. > >=20 > > I, too, am very interested in your design.
