NOTE: This example assumes that a network is connected. During its
initialization, it will try to negotiate the link speed. If you have
no network connected when you reset the board, there will be a long
delay (maybe 30 seconds?) before anything happens. That is the timeout
before the networking finally gives up and decides that no network is
available.
NOTES:
1. This example assumes that a network is connected. During its
initialization, it will try to negotiate the link speed. If you have
no network connected when you reset the board, there will be a long
delay (maybe 30 seconds?) before anything happens. That is the timeout
before the networking finally gives up and decides that no network is
available.
2. This example supports the ADC test (apps/examples/adc) but this must
be manually enabled by selecting:
CONFIG_ADC=y : Enable the generic ADC infrastructure
CONFIG_STM32_ADC3=y : Enable ADC3
CONFIG_STM32_TIM1_ADC3=y : Assign timer 1 to driver ADC3 sampling
See also apps/examples/README.txt
General debug for analog devices (ADC/DAC):
CONFIG_DEBUG_ANALOG
3. This example supports the PWM test (apps/examples/pwm) but this must
be manually enabled by selecting:
CONFIG_PWM=y : Enable the generic PWM infrastructure
CONFIG_STM32_TIM4_PWM=y : Use TIM4 to generate PWM output
See also apps/examples/README.txt
Special PWM-only debug options:
CONFIG_DEBUG_PWM
4. This example supports the CAN loopback test (apps/examples/can) but this
must be manually enabled by selecting:
CONFIG_CAN=y : Enable the generic CAN infrastructure
CONFIG_STM32_CAN1=y : Enable CAN1
CONFIG_CAN_LOOPBACK=y : Enable CAN loopback mode
See also apps/examples/README.txt
Special CAN-only debug options:
CONFIG_DEBUG_CAN
CONFIG_CAN_REGDEBUG
