1. STM8L系列，打开串口中断后，没有发送数据或者接收到数据，会进入一次发送中断。大家有此类现象吗？
2.
STM32F030RC定时器
tiME3的输入PC8，PDF资料描述为GPIO_AF_0,而官方固件函数描述为GPIO_AF_1,需配置成AF_0才能正常工作。而STM32F030R8无论软件配置成GPIO_AF_0或者GPIO_AF_1都可以正常工作。大家有此类现象吗？
3.AD输入为0电压后，配置AD为连续转换模式，AD输入电压 变高后,读出的AD转换结果仍然为0，程序代码如下，请教是否程序配置有问题。
void ADC1_Config(void)
{
ADC_InitTypeDef ADC_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
//ADC1 DeInit
ADC_DeInit(ADC1);
//GPIOC Periph clock enable
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOC, ENABLE);
//ADC1 Periph clock enable
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
//Configure ADC Channel11 as analog input
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4 ;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL ;
GPIO_Init(GPIOC, GPIO_InitStructure);
/* Initialize ADC structure */
ADC_StructInit( ADC_InitStructure);
/* Configure the ADC1 in continous mode withe a resolutuion equal to 12 bits */
ADC_InitStructure.ADC_Resolution = ADC_Resolution_10b;
ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
ADC_InitStructure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStructure.ADC_ScanDirection = ADC_ScanDirection_Backward;
ADC_Init(ADC1, ADC_InitStructure);
/* Convert the ADC1 Channel 1 with 55.5 Cycles as sampling time */
ADC_ChannelConfig(ADC1, ADC_Channel_14 , ADC_SampleTime_55_5Cycles);
/* ADC Calibration */
ADC_GetCalibrationFactor(ADC1);
/* Enable ADC1 */
ADC_Cmd(ADC1, ENABLE);
/* Wait the ADCEN falg */
while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_ADEN));
/* ADC1 regular Software Start Conv */
ADC_StartOfConversion(ADC1);
while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
flag_ad_enable = 1;
}
void batty_test()
{
static uchar low_times,high_times;
volatile uint k;
uchar bt;
if(flag_ad_enable == 0)
{
OLED_EN_1;
delay_ms(2);
ADC1_Config();
delay_ms(2);
}
k = ADC_GetConversionValue(ADC1);
batty_vol = (33*67ul*k)/(20*1024UL)+2; //补偿0.2
