Grove LED Bar - Basic Control Example
|
|
This example will show you how to use the setBits() function of this library.
|
|
Set any combination of LEDs using 10 bits.
|
|
Least significant bit controls the first LED.
|
|
|
|
The setBits() function sets the current state, one bit for each LED.
|
|
First 10 bits from the right control the 10 LEDs.
|
|
|
|
eg. 0b00000jihgfedcba
|
|
a = LED 1, b = LED 2, c = LED 3, etc.
|
|
|
|
dec hex binary
|
|
0 = 0x0 = 0b000000000000000 = all LEDs off
|
|
5 = 0x05 = 0b000000000000101 = LEDs 1 and 3 on, all others off
|
|
341 = 0x155 = 0b000000101010101 = LEDs 1,3,5,7,9 on, 2,4,6,8,10 off
|
|
1023 = 0x3ff = 0b000001111111111 = all LEDs on
|
|
| |
|
|
10 1
|
|
|
|
The bits >10 are ignored, shown here as x: 0bxxxxx0000000000
