QWave-project

Working FPGA development board with USB 2.0 interface and DSO module (125MHz analog dual channel with 16bit logic analyzer) Although hadware was implemented it is not thoroughly tested, especially analog part is not intented as ready to build kit, it is inteded for hackers and people who are wiling to play around to get it working.

Project parts

• hardware design sources of FPGA developement board and DSO module in eagle
• firmware sources of FPGA firmware in MyHDL and translated VHDL Xinix ISE project directory
• software sources of Qt based DSO sampling software

#Details:

FPGA board:

What works:

• FPGA programming and 3.3V logic interface and FT245 Sync interface (USB 2.0 speed)

TODO:

• Direct USB programming of FPGA flash - need to use JTAG and Xilinx USB Platform Cable for programming

Analog (DSO module) board:

What works:

• DSO functionality

What was not tested:

• Logic analyzer on anything faster than few kHz
• Compensation of analog input

TODO:

• Eliminating noise on analog circuits

Firmware

TODO:

• Fix trigger
• Add selectable trigger holdoff
• Do not insert trigger in single-shot mode

Software

TODO:

• Better performance
• Make more user-friendly selection of trigger
• Add exact voltage meter
