Translation - Japanese: FX2LPを使用したUSB-パラレルコンバーター - Community Translated (JA)
Question: How can I use FX2LP to make an usb to parallel converter? The data received over the USB should be made available on a parallel data bus on the GPIO pins.
There are two methods to implement a USB to Parallel interface in FX2LP.
- The GPIF or Slave FIFO mode of FX2LP can be used depending on the external device which is being interfaced with FX2LP.
- Without using the GPIF or Slave FIFO interface, firmware can be written to implement the same using the 8051 core.
