v1.3.0

Add double_trig output, hold 1st triggered trig_pixel abd update expo…

Updates

Main changes:

• added the double_trig output to check for simultaneous triggers
• changed order of trigger decision so "first" (ie. first of the 2304 pixels in the AXI4 stream) pixel ID is held
• updated the exported RTL

Fix bug in trig_pixel output of L2 trigger

v1.1.0

Fix bug in trig_pixel output

Version 1 release: updates to L2 trigger

First version with all functionality included.

Major changes in L2 trigger:

• Add triggered pixel output (a number from 0 - 2303)
• Make the trigger threshold configurable (N_BG is the number of times above background level)
• Make the lower limit of the threshold configurable (LOW_THRESH is the lowest allowed trigger threshold)

Inputs/outputs were implemented in the same way as previous IO (n_pixels in_bus and trig_data) to the trigger block.

The configurable parameters:

• N_BG is a uint8_t with an s_axilite port bundled into the CTRL_BUS
• LOW_THRESH is a uint32_t with an s_axilite port bundled into the CTRL_BUS

The output triggered pixel:

• trig_pixel is a volatile int * with an ap_ovld port

Scurve adder IP is unchanged.

First stable release of IP implemented in the Zynq board

This is the L2 trigger and Scurve adder IP as used for testing during the March 2018 campaign in TurLab at the University of Turin.
