Steven Casagrande posted an update on his open source hardware GPIB USB adapter:
After many days, I just finished off firmware version 5 for my adapter. This is probably my biggest update yet. A lot of people asked for compatibility with the Prologix commands so that’s what I focused on. Here is an overview of the new firmware:
- Nearly all Prologix command set support. The adapter should now work with some pre-existing software tools and examples on the internet that were originally intended. Some will require a few changes for baud rate and flow control settings
- Improved termination character handling
- SRQ support (but no parallel polling, only serial)
- Improved stability
- Device mode (first version so there may be fixes in the future)
- Most settings can be stored in EEPROM
- Basic FIFO buffer for data sent from the PC
