6-CHANNEL BATTERY SIMULATOR MODULE 41-752
pickering
SECTION 4 - PROGRAMMING GUIDE
RAW SUB-UNIT ACCESS
Output Sub-UnitS 1 to 6 - Voltage Sources
WARNING:
You should only use this function during calibration
Each of these sub-units appears as a 14 bit register which can be set to any binary value between 0 and 16383
(0x3FFF hexadecimal). The range of values controls the output voltage between its minimum and maximum values,
nominally 0-7 Volts.
For example, this code will set the voltage to maximum.
