# About
|
||
|
|
|
||
|
|
This is a test application for the Seeed Studio Grove LED bar module [1].
|
||
|
|
|
||
|
|
# Details
|
||
|
|
|
||
|
|
This test application will initialize a Groove LED bar with the configuration
|
||
|
|
as specified in the `grove_ledbar_params.h` file. To connect the LED bar with
|
||
|
|
your board use the following pinout:
|
||
|
|
|
||
|
|
- Pin GND is connected directly to GND.
|
||
|
|
- Pin VCC is connected directly to VCC +3.3V, or 5V if your board allows that.
|
||
|
|
- Pin DCKI is the clock pin and is connected to a free GPIO
|
||
|
|
- Pin DI is the data pin and is connected to a free GPIO, too
|
||
|
|
|
||
|
|
for the 2 latter pins note the port and pin number and adapt the Makefile
|
||
|
|
accordingly.
|
||
|
|
|
||
|
|
The test application will light up the LED bar several times, running from 0%
|
||
|
|
up to 100% and down to 0% again.
