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.

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.
