T8 Firmware

1.0028

Changes:

• Added externally clocked stream mode.

• DIO_EF index 11 (interrupt frequency input): DIO_EF_READ_B will return a timestamp of when the last measurement was captured.

Fixes:

• Fixed issue where DIO_EF index 5 configured in oneshot mode, while streaming using LJM, and reading DIO_EF_READ_A_AND_RESET, an LJME_NO_RESPONSE_BYTES_RECEIVED error will occur.

• Fixed bug with DIO_EF index 2 (pulse output) occasionally outputting an extra edge transition.

• Fixed issues with DIO_EF index 7 (high speed counter) reads while streaming.

• Fix bug with DIO_EF index 11 (interrupt frequency input) where the device would become unresponsive while streaming.

1.0026

Changes:

• Added support for hardware revision 1.3.

• Implemented watchdog timer functionality.

• Implemented POWER_LED, POWER_ETHERNET, and POWER_AIN register functionality.

• Added USER_RAM register support.

• Implemented stream start timestamp functionality.

• Implemented AIN_EF functionality.

• Implemented stream triggering.

• Implemented SHT3x support.

• Implemented UART functionality.

• DIO_EF index 11 read registers can no longer return an inf value.

• The default stream buffer size was increased to 16384 bytes. Additionally, the stream buffer can no longer be set to a lower size than default.

• After changing device resolution and sampling rate settings, the digital filtering on the ADC's require 3 samples before valid results are returned. Firmware will now wait 3 sampling periods and toss the invalid readings before returning an AIN reading rather than returning the 3 invalid values.

Fixes:

• DIO_EF floating point value reads (f.e. DIO#_EF_READ_A_F) now work correctly.

• LUA_NO_WARN_TRUNCATION no longer returns an error, it does nothing. The register does not impact any functionality because Lua on the T8 uses double precision floating point numbers.

• Fixed bad One-Shot behavior for DIO_EF index 11.

• Fixed DIO_EF index 3,4 bad READ_AND_RESET behavior.

• Fixed bad DIO_EF index 12 One-Shot behavior and added a disable mode.

• Fixed the Ethernet DHCP factory setting and a related DHCP enable bug.

• Stream burst is cleared on stream disable.

1.0010

Fixes:

• Improvements to stream stop, DAC clock, and DIO_EF input capture functionality to increase feature reliability.

Known Issues:

• Certain stream scan rates can cause the errors LJME_COULD_NOT_START_STREAM or LJME_RECONNECT_FAILED when starting stream.

• StreamBurst causes the error STREAM_BURST_COMPLETE to be returned if you try to run a regular stream after StreamBurst.

• USER_RAM and LUA_NO_WARN_TRUNCATION registers return an error when accessed.

• DIO_EF floating point register reads can return erroneous data.

1.0007

Changes:

• Reading from any AIN will now throw an error if the AIN system is not properly configured.

• Modified the stream packet sizes to increase the network stack reliability.

Fixes:

• Valid DIO stream targets no longer throw an illegal address error.

1.0004

Changes:

• TEMPERATURE registers will return -9999 if the AIN system rate is greater than 250 Hz.

Fixes:

• AIN configuration time improved.

1.0003

Changes:

• Reading TEMPERATURE registers while streaming will now throw an error.

Fixes:

• TEMPERATURE registers return proper values after streaming.

1.0002

Additions:

• STREAM_OUT#_BUFFER_STATUS support.

Fixes:

• Socket connections no longer require (up to) 30 seconds before reconnection.

1.0000

Fixes:

• All AIN gain/range settings now return valid results, not just the ±11 V setting.

0.9999

Additions:

• Stream Burst support.

0.9998

Additions:

• Enabled Lua script save and run at startup.
