今天又看了看wifi相关的一些资料乱人眼啊
决定给前段时间的结果上添加的东东
正好手上有个NTC的模块，使使AD吧
顺道爬墙出去找了一些labview的控件
关于AD的使用，MXCHIP使用的STM32库似乎比较旧
这里使用ADC1的通道1，对应GPIO_PA1
- void ADC1_CH1_DMA_Config(void)
- {
- ADC_InitTypeDef ADC_InitStructure;
- ADC_CommonInitTypeDef ADC_CommonInitStructure;
- DMA_InitTypeDef DMA_InitStructure;
- GPIO_InitTypeDef GPIO_InitStructure;
-
- RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2 | RCC_AHB1Periph_GPIOA, ENABLE);
- RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
-
- // DMA_DeInit(DMA2_Stream0);
- /* DMA2 Stream0 channe0 configuration **************************************/
- DMA_InitStructure.DMA_Channel = DMA_Channel_0;
- DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)ADC1_DR_Address;
- DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)&ADC_ConvertedValue;
- DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;
- DMA_InitStructure.DMA_BufferSize = 2;
- DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
- DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
- DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
- DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
- DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
- DMA_InitStructure.DMA_Priority = DMA_Priority_High;
- DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Disable;
- DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
- DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;
- DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
- DMA_Init(DMA2_Stream0, &DMA_InitStructure);
- DMA_Cmd(DMA2_Stream0, ENABLE);
-
- /* Configure ADC1 Channe6 pin as analog input ******************************/
- GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
- GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
- GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL ;
- GPIO_Init(GPIOA, &GPIO_InitStructure);
-
- /* ADC Common Init **********************************************************/
- ADC_CommonInitStructure.ADC_Mode = ADC_Mode_Independent;
- ADC_CommonInitStructure.ADC_Prescaler = ADC_Prescaler_Div2;
- ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;
- ADC_CommonInitStructure.ADC_TwoSamplingDelay = ADC_TwoSamplingDelay_5Cycles;
- ADC_CommonInit(&ADC_CommonInitStructure);
-
- /* ADC1 Init ****************************************************************/
- ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b;
- ADC_InitStructure.ADC_ScanConvMode = ENABLE;
- ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
- ADC_InitStructure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;
- ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
- ADC_InitStructure.ADC_NbrOfConversion = 2;
- ADC_Init(ADC1, &ADC_InitStructure);
-
- /* ADC1 regular channe6 configuration *************************************/
- ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_3Cycles);
- // ADC_RegularChannelConfig(ADC1, ADC_Channel_7, 2, ADC_SampleTime_3Cycles);
- /* Enable DMA request after last transfer (Single-ADC mode) */
- ADC_DMARequestAfterLastTransferCmd(ADC1, ENABLE);
-
- /* Enable ADC1 DMA */
- ADC_DMACmd(ADC1, ENABLE);
-
- /* Enable ADC1 */
- ADC_Cmd(ADC1, ENABLE);
-
- }
还好一切正常
配置过程和STM32一样，不啰嗦了
结果就出来这个视频了
庆科的WIFI，架构还不是特别明晰
指导文档中只有UDP的代码运行流程，能补充一下TCP/IP的么
