Chapter 2. API Reference
• UART configuration
ADC configuration Contains:
• CONFIG_ADC_DISABLE_DAC
• CONFIG_ADC_FORCE_XPD_FSM
CONFIG_ADC_FORCE_XPD_FSM
Use the FSM to control ADC power
Found in: Component config
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.
Default value:
• No (disabled)
CONFIG_ADC_DISABLE_DAC
Disable DAC when ADC2 is used on GPIO 25 and 26
Found in: Component config
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.
Default value:
• Yes (enabled)
MCPWM configuration
• CONFIG_MCPWM_ISR_IN_IRAM
CONFIG_MCPWM_ISR_IN_IRAM
Place MCPWM ISR function into IRAM
Found in: Component config
If this option is not selected, the MCPWM interrupt will be deferred when the Cache is in a disabled
state (e.g. Flash write/erase operation).
Note that if this option is selected, all user registered ISR callbacks should never try to use cache as well.
(with IRAM_ATTR)
Default value:
• No (disabled)
SPI configuration Contains:
• CONFIG_SPI_MASTER_ISR_IN_IRAM
• CONFIG_SPI_SLAVE_ISR_IN_IRAM
• CONFIG_SPI_MASTER_IN_IRAM
• CONFIG_SPI_SLAVE_IN_IRAM
