| - | **Step 5:** Write some data to EP4. Due to a limitation of the example the data must not be larger then 1024 bytes. | ||

| - | $ (echo write 7 18 4; cat Readme) | nc localhost 9081 | ||

| - | ------ | ||
| - | |||
| - | THIS EXAMPLE IS INTENDED FOR ZTEX USB-FPGA-MODULES. | ||
| - | |||
| - | THE FIRMWARE (DEFINED IN UCECHO.C) DECLARES ENDPOINT 2 AND ENDPOINT 4 | ||
| - | (BOTH 512 BYTES, DOUBLE BUFFERED, BULK TRANSFER, BELONG TO INTERFACE 0). | ||
| - | ALL DATA THAT IS WRITTEN TO ENDPOINT 4 IS CONVERTED TO UPPERCASE BY | ||
| - | THE FPGA AND CAN BE READ BACK FROM ENDPOINT 2. | ||
| - | |||
| - | THIS EXAMPLE DOES THE SAME AS THE EXAMPLE IN DIRECTORY ../ | ||
| - | EXCEPT THAT THE UPPERCASE - LOWERCASE CONVERSION IS MADE BY THE FPGA. | ||
| - | |||
| - | THE DRIVER (DEFINED IN UCECHO.JAVA) UPLOADS THE THE FIRMWARE (UCECHO.IHX) | ||
| - | TO THE EZ-USB MICROCONTROLLER AND THE BITSTREAM (FPGA/ | ||
| - | FPGA IF NECESSARY, SENDS USER STRING TO THE DEVICE AND READS THEM BACK. | ||
| - | |||
| - | UPLOADING THE FIRMWARE TO EEPROM IS ALSO SUPPORTED BY THE FIRMWARE (E.G. | ||
| - | USING THE FWLOADER UTILITY). | ||
| - | |||
| - | THIS EXAMPLE MAY SERVE A GOOD STARTING POINT FOR OWN PROJECTS. | ||
