Description
SECO − NCV7685RGB − GEVB is an evaluation board for RGB
LEDs lighting application with BLE in automotive which driven by
NCV7685 and controlled by RSL10. It is also an interior or exterior
lighting reference design for tail or ambient lights to realize general
sequential or high end pixelated LEDs controlling in
− vehicle network.
The user can set RGB LED’s color and intensity by mobile APP to
show customized information or animation.
In general, the user prefers to use fixed address in multiple
NCV7685 applications. It leads to additional procedure to
pre
− program each chips’ address in mass production stage. In
addition, it is inconvenient for maintenance in the aftermarket. In
firmware of this evaluation board, it uses floating address setting
method, each time when power on the board, NCV7685 will be
assigned an address which is defined by user, but it’s not locked into
OTP registers. The user can realize this function by using either
RSL10’s GPIO or IO expender (PAC9655).
In firmware, the driver APIs are divided into four levels: Peripheral,
Chip, Board and customer application. User can directly include the
chips and board APIs in their own project, and modify the application
APIs according to their applications. This will accelerate developing
period to market.
The board conceived for use as a plug and play environment to
testing.
Nominal supply voltage is 12 V (Supply voltage range 12 − 24 V). In
switch mode, four fixed animations shown; the RGB LEDs’ color and
intensity setting by user mobile APP in BLE mode.
