Prior sending the Dac word CS SCLK
Sending the Dac word (117)d = 10100001110101
DONE • Checked the CS signal • Checked the SCLK • Checked the data word”Din” • The Dacs are set successfully: Vth = -35mV (dac=105), Vfp = 0.6V (dac=158), Vfs = 0.5V (dac=165), Vrc = 1.4V (dac=213).
Standing point: Done & To do… We finished successfully: • The FPGA Initialization. • The DACS Initialization. • Bringing the C++ based DAQ to the same level of the New Labview based DAQ before the latest changes. &We are working on: • ASICS initialization (then we can test the C++ again). • Preparing the DAQ for data readout.
