Controller of the interferometer

2001, 2003 (2 months), customer: “Sumix Corporation”, outsourcing, 2 developers (with my father)
result: was designed and 2 controllers were implemented
OS: Windows 98; languages: C51; tools: oscilloscope & solder iron

AT89C52 based external interferometer controller had 4 10-bits DAC controlled LED channels with current intensity control, external and internal temperature sensors.
One 12-bit DAC output channel has slow but very low noise -40V-+300 output amplifier for piezo-positioner control. FW was written by my father. Controller has COM port PC interface.
Each channel may be programmed for auto incrementing with specified start value, value step and sign, start delay and step interval.
Multi-voltage power supplier was included.
