See include/nuttx/timers/pwm.h for further PWM driver information. if PWM config PWM_PULSECOUNT bool "PWM Pulse Count Support" default n depends on ARCH_HAVE_PWM_PULSECOUNT ---help--- Some hardware will support generation of a fixed number of pulses. This might be used, for example to support a stepper motor. If the hardware will support a fixed pulse count, then this configuration should be set to enable the capability. config PWM_OVERWRITE bool "PWM Overwrite Support" default n depends on ARCH_HAVE_PWM_OVERWRITE ---help--- Some hardware will support generation of a pin overwrite with 0 or 1 without the need to wait for an end of cycle. The overwrite is controlled from an application level the same way duty cycle or frequency is modified. config PWM_DEADTIME bool "PWM Deadtime Support" default n depends on ARCH_HAVE_PWM_DEADTIME ---help--- Some hardware will support deadtime generators that automatically insert output activation delay for complementary PWM outputs. This is usefull for H-bridge motor control for example. The deadtime values are set from application level via the same IOCTL that sets up duty cycle and frequency. For detailed description about deadtime functionality please refer to architecture manuals and datasheets. config PWM_MULTICHAN bool "PWM Multiple Output Channel Support" default n depends on ARCH_HAVE_PWM_MULTICHAN depends on !PWM_PULSECOUNT ---help--- Enables support for multiple output channels per timer. if PWM_MULTICHAN config PWM_NCHANNELS int "Number of Output Channels Per Timer" default 1 range 1 16 ---help--- Specifies the number of output channels per timer.

See include/nuttx/timers/rtc.h for further RTC driver information. Most RTC drivers are MCU specific and may require other specific settings. if RTC config RTC_DATETIME bool "Date/Time RTC Support" default n ---help--- There are two general types of RTC: (1) A simple battery backed counter that keeps the time when power is down, and (2) a full date / time RTC the provides the date and time information, often in BCD format. If RTC_DATETIME is selected, it specifies this second kind of RTC. In this case, the RTC is used to "seed" the normal NuttX timer and the NuttX system timer provides for higher resolution time. if !RTC_DATETIME config RTC_HIRES bool "Hi-Res RTC Support" default n ---help--- If RTC_DATETIME not selected, then the simple, battery backed counter is used. There are two different implementations of such simple counters based on the time resolution of the counter: The typical RTC keeps time to resolution of 1 second, usually supporting a 32-bit time_t value. In this case, the RTC is used to "seed" the normal NuttX timer and the NuttX timer provides for higherresoution time. If RTC_HIRES is enabled in the NuttX configuration, then the RTC provides higher resolution time and completely replaces the system timer for purpose of date and time. config RTC_FREQUENCY int "Hi-Res RTC frequency" default 1 depends on RTC_HIRES ---help--- If RTC_HIRES is defined, then the frequency of the high resolution RTC must be provided. If RTC_HIRES is not defined, RTC_FREQUENCY is assumed to be one Hz. config RTC_ADJTIME bool "RTC Adjustment Support" default N depends on RTC_HIRES ---help--- Enable support for adjtime() to adjust RTC run rate.

This allows you to add architecture-specific RTC operations to the RTC interface endif # RTC_DRIVER config RTC_EXTERNAL bool "External RTC Support" default n ---help--- In modern MCUs, the RTC is usually implement as an internal peripheral to the MCU. An option is to use an external RTC connected to the MCU typically via SPI or I2C. If an external RTC is connect to the MCU through some bus, then the RTC will not be available to the system until after the system fully boots up and is able to access the bus. In that case, this setting must be included to suppress attempts to initialize the RTC early in the boot sequence. config RTC_DSXXXX bool "DS130x/DS323x RTC Driver" default n select I2C select RTC_DATETIME depends on RTC_EXTERNAL ---help--- Enables support for the Maxim Integrated DS3231 I2C RTC timer. if RTC_DSXXXX choice prompt "Maxim Integrated RTC" default RTC_DS3231 config RTC_DS1302 bool "DS1302" ---help--- Enables support for the Maxim Integrated DS1302 serial RTC timer. config RTC_DS1307 bool "DS1307" ---help--- Enables support for the Maxim Integrated DS1307 I2C RTC timer. config RTC_DS3231 bool "DS3231" ---help--- Enables support for the Maxim Integrated DS3231 I2C RTC timer. config RTC_DS3232 bool "DS3232" ---help--- Enables support for the Maxim Integrated DS3232 I2C RTC timer. config RTC_DS3234 bool "DS3234" depends on EXPERIMENTAL ---help--- Enables support for the Maxim Integrated DS3234 SPI RTC timer.
