This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.

a3load is 8051 firmware that can be used for uploading or downloading to EZ-USB RAM (internal or external). It implements the vendor specific command bRequest = 0xA3. The address to download/upload to/from is specified in the wValue field of the SETUP packet and the length of the transfer in the wLength field. The actual upload/download data is transferred during the DATA stage of the SETUP transfer. This firmware will function on all EZ-USB chips (EZ-USB, EZ-USB FX, FX2, FX2LP, FX1).

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.
