工具/软件：
您好：
我有一个工程使用 Timer0 来触发 ADC 转换。 Timer0 周期设置为 1.125s、而计时器时钟频率设置为 3.64KHz。
事件发布者为 Timer0、事件订阅者为 ADC12_0。 转换每 100us 发生一次。 但我找不到在 SYSCFG 中配置 100us 的位置。
以下是 ti_msp_dl_config.c 中的 ADC12_0 初始化函数：
SYSCONFIG_WEAK void SYSCFG_DL_ADC12_0_init(void)
{
DL_ADC12_setClockConfig(ADC12_0_INST, (DL_ADC12_ClockConfig *) &gADC12_0ClockConfig);
DL_ADC12_initSeqSample(ADC12_0_INST,
DL_ADC12_REPEAT_MODE_ENABLED, DL_ADC12_SAMPLING_SOURCE_AUTO, DL_ADC12_TRIG_SRC_EVENT,
DL_ADC12_SEQ_START_ADDR_00, DL_ADC12_SEQ_END_ADDR_03, DL_ADC12_SAMP_CONV_RES_12_BIT,
DL_ADC12_SAMP_CONV_DATA_FORMAT_UNSIGNED);
DL_ADC12_configConversionMem(ADC12_0_INST, ADC12_0_ADCMEM_2,
DL_ADC12_INPUT_CHAN_2, DL_ADC12_REFERENCE_VOLTAGE_VDDA, DL_ADC12_SAMPLE_TIMER_SOURCE_SCOMP0, DL_ADC12_AVERAGING_MODE_DISABLED,
DL_ADC12_BURN_OUT_SOURCE_DISABLED, DL_ADC12_TRIGGER_MODE_AUTO_NEXT, DL_ADC12_WINDOWS_COMP_MODE_DISABLED);
DL_ADC12_configConversionMem(ADC12_0_INST, ADC12_0_ADCMEM_3,
DL_ADC12_INPUT_CHAN_3, DL_ADC12_REFERENCE_VOLTAGE_VDDA, DL_ADC12_SAMPLE_TIMER_SOURCE_SCOMP0, DL_ADC12_AVERAGING_MODE_DISABLED,
DL_ADC12_BURN_OUT_SOURCE_DISABLED, DL_ADC12_TRIGGER_MODE_AUTO_NEXT, DL_ADC12_WINDOWS_COMP_MODE_DISABLED);
DL_ADC12_setPowerDownMode(ADC12_0_INST,DL_ADC12_POWER_DOWN_MODE_MANUAL);
DL_ADC12_setSampleTime0(ADC12_0_INST,20);
DL_ADC12_setSampleTime1(ADC12_0_INST,50);
DL_ADC12_setSubscriberChanID(ADC12_0_INST,ADC12_0_INST_SUB_CH);
/* Enable ADC12 interrupt */
DL_ADC12_clearInterruptStatus(ADC12_0_INST,(DL_ADC12_INTERRUPT_MEM2_RESULT_LOADED
| DL_ADC12_INTERRUPT_MEM3_RESULT_LOADED));
DL_ADC12_enableInterrupt(ADC12_0_INST,(DL_ADC12_INTERRUPT_MEM2_RESULT_LOADED
| DL_ADC12_INTERRUPT_MEM3_RESULT_LOADED));
DL_ADC12_enableConversions(ADC12_0_INST);
}
以下是 ti_msp_dl_config.c 中的 Timer0 初始化函数：
SYSCONFIG_WEAK void SYSCFG_DL_TIMER_0_init(void) {
DL_TimerG_setClockConfig(TIMER_0_INST,
(DL_TimerG_ClockConfig *) &gTIMER_0ClockConfig);
DL_TimerG_initTimerMode(TIMER_0_INST,
(DL_TimerG_TimerConfig *) &gTIMER_0TimerConfig);
DL_TimerG_enableClock(TIMER_0_INST);
DL_TimerG_enableEvent(TIMER_0_INST, DL_TIMERG_EVENT_ROUTE_1, (DL_TIMERG_EVENT_ZERO_EVENT));
DL_TimerG_setPublisherChanID(TIMER_0_INST, DL_TIMERG_PUBLISHER_INDEX_0, TIMER_0_INST_PUB_0_CH);
}
我想这肯定是我错过的地方。 您能为此提供帮助吗？
谢谢！
