libaps2 v0.5

Minimum compatible firmware: v2.20

N.B. there have been API changes

N.B. this update requires an update to the boot sequence stored in non-volatile memory. This is updated by running the flash command line program with the --SPI option.

Software

• libaps2 error reporting
• complete Matlab and Julia drivers
• command-line program clean-ups
• FPGA die temperature exposed
• improved documentation
• improved test coverage (ethernet comms. and DAC BIST)

Hardware

• improved LED status notification
• die temperature reporting
• full 128k sample waveform cache
• PLL lock robustness
• bug-fix: DAC bit errors
• (v2.24+ only) SATA input interface connected to sequence steering register

libaps2 v0.4

Companion firmware version 2.12

Enhancements:

• software trigger support
• fleshed out MATLAB driver
• play_waveform command line program
• documentation
• DAC BIST support for data-integrity testing

Bug-fixes:

• DAC FIFO's are adjusted for stability (#12)
• single channel waveform mode on Ch B is supported (#11)

libaps2 v0.3

• Fixes hang when unloading driver on Windows
• Simplifies API by removing init() method (initialization happens automatically)
• Adds MATLAB wrapper
• ASIO dependency now handled with a git submodule

libaps2 v0.2

Changes:

• Fixes set_channel_offset()
• Renames get_bitfile_version() to get_firmware_version()
• Minor updates to test code

First release

Initial driver release that is compatible with the 2.x firmware series. The sequencer mode of operation is well-tested for individual APS2 modules. Decisions about waveform mode and multi-module aggregation are deferred until later releases.
