Quick Easy Job: Write High Speed Serial Interface for FT232H

Postby fullspeceng » Sat Jul 02, 2011 4:00 am

We're looking for someone to write the high speed serial interface for the FTDI FT232H using either the high speed serial or FT1248 interface. High speed serial should operate at 12mbps. We were able to get around 3.3mbps sustained output using highspeed serial on the first try. We could optimize this internally but wanted this simple job to evaluate possible partnerships with outside developers.

Interface specs are here: http://www.ftdichip.com/Products/ICs/FT232H.htm

We will pay for FT232H module + $200 for this mini job. If you are a proven XMOS developer, we will supply the module up front. If you are not, we will refund the module + the fee after the job is done.

You can loop 1mByte data from the PC using the D2xx driver. End result must be higher than 8mbps sustained read (just copy the byte of data into a circular array).

We are willing to opensource the end result and add it to the repository for all to benefit.

Note must be 1 bit interface (4 lines) of FT1248 or the 4 line high speed serial.

Why not use SPI , for low speed (<=25Mbps) it´s better because it allows for galvanic isolation,
spi memory update and shares the same pins as the memory device.

SPI is master mode only on FT232H.

If you can implement slave mode at 12MHz then this is ok.
