The FRDM-HB2000FEVM, in conjunction with a FRDM-KL25Z board (shipped with the
kit), can evaluate the design by means of a GUI, any MCU with GPIO or with simple lab
equipment. A FRDM-KL25Z-compatible GUI and MCU program are available online at
the following link: http://www.nxp.com/FRDM-HB2000FEVM .
The FRDM-HB2000FEVM is compatible with any Arduino
™
platform board. However, if
a board other than the FRDM-KL25Z is used, MCU code must be written to work with the
board.
4.7 Input signal definitions
The following input signals control the outputs or functions inside the circuit.
Table 5. Input signal definitions
Input name Description
DIS Disable signal to tri-state the outputs
ENBL Disable signal to tri-state the output and put the part in Sleep mode
IN1 Logic input to control OUT1
IN2 Logic input to control OUT2
MOSI Master out slave input for the SPI
CS_B Chip select bar input for the SPI
SCLK Clock for the SPI
4.8 Output signal definitions
The FRDM-HB2000FEVM uses the following output signals to drive a load such as
a brushed DC motor. The board provides an analog output for real time load current
monitoring. This signal allows closed-loop control of the load.
