I have developed the following design as the framework for the bus interface of USB2 interfaced FPGA based instruments.   This firmware in intended to aid the design of instrumentation using the Morph-IC-II module and other fpga systems interfaced to the USB2 bus using FTDI's FT2232H interface chip.   It has been in use in prototype form in my NMR laboratory as the heart of a number of instruments (contributing to a number of papers), and would I believe aid the design of other FPGA ba ...
So now that I have a working display I guess I had better get started on the SPI temperature sensor. The design process here is a little different as we are not just passing data or signals from one block to the next. What we need is a sub block that can process a few instruction to pull in the data from the SPI device.   Now in some cases you may consider a state machine, but no. we first need to look at and think about what the SPI device delivers. The device I’ll be usin ...
