v0.11.2

• Fix bug in the FPGA image. The PDM output for channels 2-4 was always off in the reset manager.
• Fix communication bugs in the Julia client

v0.11.0

Breaking Changes

• Breaking: Updated ADC and DAC pipeline requires a new ADC and DAC calibration after the update!
• Breaking: When not using the ADC calibration the integer values will now be in the range of [-32768, 32767] instead of [-8192, 8191]

Updated ADC Pipeline

• The decimating pipeline after the ADC now uses the full 16-bit accuracy decreasing the quantization noise which becomes dominant over the ADC noise at high decimations (>256)
• The FIR filter added in v0.6.0 can now be switched on and off using firEnabled!. For all standard applications the filter should be left on for improved anti-aliasing and flatter frequency response. The filter can be turned off for applications where the delay introduced by the filter is unwanted, e.g. time-based multiplexing

Updated DAC Pipeline

• increased amplitude resolution of waveform signal components to 16-bit, decreasing the discretization of the sine amplitude from 122 µV to 15 µV
• increase resolution of DAC pipeline to 16-bit until the final output quantization for improved accuracy when combining different components
• prevent potential overflow in DAC pipeline when adding multiple components
• reintroduced signal limiter, which was mistakenly removed in a previous release
• removed hard limit of 1 V from amplitude components, as the DAC might be able to produce higher amplitudes depending on the calibration

General Updates

• extended instant reset to ramp down the outputs if ramping is enabled instead of cutting
• (re)added SCPI interface to enable instant reset
• added 3-bit counter output with configurable counter speed outputting on DIO2_N (LSB) to DIO4_N (MSB)
• Improved passing of error messages from SCPI server to the Julia client, SCPI errors still do not throw, but additional info is output as log messages
• added calibReset!(rp) to reset ADC and DAC calibration to default
• added serverversion(rp) to query the version of the server running of the RedPitaya
• improved imgversion to not error on server versions prior to the introduction
• added two examples on FIR switching
• deprecated enableRampDown! and enableRampDown due to misleading names and functionality. Use startRampDown!(rp, channel) in the future to start a ramp down. It is not and was never possible to stop a triggered ramp down contrary to what the existence of enableRampDown!(rp, channel, false) might suggest.
