menu "PWM Test" config RT_UTEST_PWM bool "PWM Frequency and Duty-cycle Matrix Test" default n select RT_USING_PWM help Run configurable PWM groups. Channels in one group run concurrently, while groups run in order. Each channel can keep a fixed output, sweep once and hold its last point, or repeat its sweep for the group duration. if RT_UTEST_PWM config RT_PWM_TC_CONFIG_FILE string "PWM test configuration header" default "pwm_tc_config.h" help The header defines PWM_TC_GROUPS and PWM_TC_GROUP_COUNT. Keep the default for the built-in example, or provide a board-specific header from a compiler include path. Channel enable switches, device names, channel numbers, output modes, and waveform points are kept in that header because Kconfig cannot represent dynamic group/channel arrays. config RT_PWM_TC_MAX_CHANNELS int "Maximum concurrent channels in one PWM test group" range 1 64 default 8 help This limits enabled channels, not the total number of configured and disabled channel entries in a group. config RT_PWM_TC_TIMEOUT int "PWM test timeout in seconds" range 1 3600 default 30 help Abort the PWM matrix when the total test runtime reaches this limit. endif endmenu
