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.
