Plotting data from adc in matlab

code is below. How can I plot the dene[i] in code in matlab?

#include <stm32f4xx.h>
#include <stm32f4xx_conf.h>
#include <stm32f4xx_rcc.h>

int i;

static char dene2[2048];
static char dene3[2048];
static char dene4[2048];
static char dene5[1808];

float dum1;
int ms10Ticks; /* counts 1ms timeTicks */

/*----------------------------------------------------------------------------
SysTick_Handler

void SysTick_Handler(void) {
ms10Ticks++;
ADC_SoftwareStartConv(ADC1);//ADC1->CR2 |= (1<<30);
}

/*----------------------------------------------------------------------------
MAIN function
*----------------------------------------------------------------------------*/
int main (void) {

RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD,ENABLE);
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC,ENABLE);

GPIO_StructInit(&alper);
alper.GPIO_Pin = GPIO_Pin_5;//The channel 15 is connected to PC5
alper.GPIO_Mode = GPIO_Mode_AN; //The PC5 pin is configured in analog mode
alper.GPIO_PuPd = GPIO_PuPd_NOPULL; //We don't need any pull up or pull down
GPIO_Init(GPIOC,&alper);//Affecting the port with the initialization structure configuration

//GPIOC->MODER |= (3<<10); // PC5--> ADC.15 input olarak ayarla
//GPIOC->PUPDR = 0x00000000; // pull up-down yok

ADC_DeInit();
ADC_init_structure.ADC_DataAlign = ADC_DataAlign_Right;//data converted will be shifted to right
ADC_init_structure.ADC_Resolution = ADC_Resolution_12b;//Input voltage is converted into a 12bit number giving a maximum value of 4096
ADC_init_structure.ADC_ContinuousConvMode = DISABLE; //the conversion is continuous, the input data is converted once
ADC_init_structure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;//no trigger for conversion
ADC_init_structure.ADC_NbrOfConversion = 1;
ADC_init_structure.ADC_ScanConvMode = DISABLE;//The scan is configured in one channel

ADC_RegularChannelConfig(ADC1,ADC_Channel_15,1,ADC_SampleTime_144Cycles);

SystemCoreClockUpdate(); /* Get Core Clock Frequency */
if (SysTick_Config(SystemCoreClock / 10000)) { /* SysTick 10 msec interrupts */
while (1); /* Capture error */
}


while(1) { /* Loop forever */
if(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC)){//if((ADC1->SR & 0x00000002))

if(i<2048)

dene1[i]=(ADC_GetConversionValue(ADC1));
else if(i>2048 && i<4096)
dene2[i-2048]=(ADC_GetConversionValue(ADC1));
else if(i>4096 && i<6144)
dene3[i-4096]=(ADC_GetConversionValue(ADC1));
else if(i>6144 && i<8192)
dene4[i-6144]=(ADC_GetConversionValue(ADC1));
else
dene5[i-8192]=(ADC_GetConversionValue(ADC1));
i++;
if(i==10000){
i=0;
}

}

}

  • Use EventRecorder functions to send the samples to the debugger, and use the debugger command ER to save the EventRecorder items to a comma-separated values (.CSV) file. Matlab can import data from .csv files. You may need to edit the .csv file to format the file before Matlab will import it properly, e.g., to remove non-numeric data. 

    EventRecorder is well documented in the online help.
