ADC power can be controlled by the FSM instead of software. This allows the ADC to
|
|
be shut off when it is not working leading to lower power consumption. However

using the FSM control ADC power will increase the noise of ADC.

If this is set, the ADC2 driver will disable the output of the DAC corresponding to the specified

channel. This is the default value.

For testing, disable this option so that we can measure the output of DAC by internal ADC.

Place the TWAI ISR in to IRAM. This will allow the ISR to avoid

configuration structure when installing the driver (see docs for

specifics).

help
|
|
When the bus-off condition is reached, the REC should be reset to 0 and frozen (via LOM) by the
|
|
driver's ISR. However on the ESP32, there is an edge case where the REC will increase before the
|
|
driver's ISR can respond in time (e.g., due to the rapid occurrence of bus errors), thus causing the
|
|
REC to be non-zero after bus-off. A non-zero REC can prevent bus-off recovery as the bus-off recovery
|
|
condition is that both TEC and REC become 0. Enabling this option will add a workaround in the driver
|
|
to forcibly reset REC to zero on reaching bus-off.

On the ESP32, when receiving a data or remote frame, if a bus error occurs in the data or CRC field,

the data of the next received frame could be invalid. Enabling this option will add a workaround that
