|
Place DAC control functions (e.g. 'dac_oneshot_output_voltage') into IRAM,
|
||
|
so that this function can be IRAM-safe and able to be called in the other IRAM interrupt context.
|
||
|
Enabling this option can improve driver performance as well.

|

Ensure the DAC interrupt is IRAM-Safe by allowing the interrupt handler to be
|
||
|
executable when the cache is disabled (e.g. SPI Flash write).

Wether to suppress the deprecation warnings when using legacy DAC driver (driver/dac.h).
|
||
|
If you want to continue using the legacy driver, and don't want to see related deprecation warnings,
|
||
|
you can enable this option.

Wether to enable the debug log message for DAC driver.

Note that, this option only controls the DAC driver log, won't affect other drivers.

help
|

|
Whether to left shift the continuous data to align every bytes to 16 bits in the driver.
|
||
|
On ESP32, although the DAC resolution is only 8 bits,
|
||
|
the hardware requires 16 bits data in continuous mode.
|
||
|
By enabling this option, the driver will left shift 8 bits for the input data automatically.
|
||
|
Only disable this option when you decide to do this step by yourself.
|
||
|
Note that the driver will allocate a new piece of memory to save the converted data.
