2.1
Installation
The FPC401 EVM GUI has two installers. The
Setup_FPC401_EVM.exe
installer does not contain the
National Instruments Run-Time Engine
and requires web access to download the NI run-time engine if the
computer does not already have this installed. The
Setup_FPC401_EVM_with_RTE.exe
installer is a
larger file that contains the run-time engine and does not require web access. Select the appropriate
installer and follow the installer wizard to install the FPC401 EVM GUI.
2.2
Initializing Communication
To initialize communication with the FPC401EVM, first select the number of FPC401s under
FPC Count
and the protocol (I2C or SPI), highlighted by
. Click
OPEN LINK
to establish communication with
the MSP430 through USB and initialize the device. In I2C mode, this will configure the MSP430 and
automatically configure the I2C addresses of all connected FPC401s so that each one has a unique
address. In SPI mode, this will configure the MSP430 and establish the length of the SPI message. Each
time the hardware configuration changes, the link must be reestablished. For example, connecting
additional FPC401s or changing the communication from I2C to SPI requires the link to be reestablished.
The
TOGGLE LED
button will toggle the LED (D7) for a visual indication that the USB communication is
working. The text in the bottom of the GUI should say
CONNECTED
and turn green after USB
communication is established. Note that this means that the computer is communication with the MSP430
but does not necessarily mean that communication is established with the FPC401.
The
CLOSE LINK
button will terminate USB communication.
