Enable DAC LED driver.
|
|
|
|
The driver is normally used with a VCCS (Voltage Controlled Current
|
|
Source) between the DAC and the LED.
|
|
|
|
It might be possible to use this driver to supply an LED directly
|
|
from a DAC, but LED_PWM is most likely more suited for this purpose.
|
|
If the DAC is used without a VCCS, its capabilities should be checked
|
|
carefully, and the output buffer should be enabled.
