|
|
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.

Normally only the ISR of SPI master is placed in the IRAM, so that it

For other functions, there's some possibility that the flash cache

miss when running inside and out of SPI functions, which may increase

the interval of SPI transactions.

Enable this to put ``queue_trans``, ``get_trans_result`` and

During unit test, this is enabled to measure the ideal case of api.

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

cache misses, and also be able to run whilst the cache is disabled
|
|
(such as when writing to SPI Flash).

Note that if this option is enabled:
|
|
- Users should also set the ESP_INTR_FLAG_IRAM in the driver
|
|
configuration structure when installing the driver (see docs for
|
|
specifics).
|
|
- Alert logging (i.e., setting of the TWAI_ALERT_AND_LOG flag)
|

will have no effect.

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 a transmit interrupt occurs, and interrupt register is read on the same APB clock

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

will reset the peripheral on detection of this errata condition. Note that if a frame is transmitted on

the bus whilst the reset is ongoing, the message will not be receive by the peripheral sent on the bus
