基于STM32F103采集ADC电压在一块芯片为ST7789分辨率为172×320的屏幕上显示

要实现基于STM32F103采集ADC电压在一块芯片为ST7789分辨率为172×320的屏幕上显示，需要进行以下步骤：

1. 硬件连接：将STM32F103的ADC模块连接到需要采集的电压源上，同时将ST7789屏幕连接到STM32F103的SPI接口上。

2. 编写ADC采集程序：使用STM32CubeMX生成工程，配置ADC模块的通道和采样频率，编写采集程序并将采集到的电压值存储到变量中。

3. 编写屏幕显示程序：使用STM32CubeMX生成工程，配置SPI接口，编写屏幕显示程序，将采集到的电压值显示在屏幕上。

4. 调试程序：将程序烧录到STM32F103上，进行调试，确保程序能够正常运行并显示正确的电压值。

需要注意的是，在编写程序时需要注意屏幕的分辨率和显示方式，以确保能够正确显示电压值。同时，还需要注意ADC采样时的噪声和精度问题，以确保采集到的电压值准确无误。

基于stm32f103在一块芯片为ST7789分辨率为172×320的屏幕上输出ADC电压的代码

以下是基于stm32f103的代码，可以在ST7789分辨率为172×320的屏幕上输出ADC电压。

首先需要初始化ADC模块和LCD屏幕：

#include "stm32f10x.h"
#include "stdio.h"

void ADC_Configuration(void);
void LCD_Configuration(void);

int main(void)
{
    uint16_t adc_value;
    char voltage_str[16];

    ADC_Configuration();
    LCD_Configuration();

    while (1)
    {
        // Start ADC conversion
        ADC_SoftwareStartConvCmd(ADC1, ENABLE);

        // Wait for ADC conversion to complete
        while (ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);

        // Read ADC value
        adc_value = ADC_GetConversionValue(ADC1);

        // Convert ADC value to voltage
        float voltage = adc_value * 3.3 / 4095;

        // Format voltage as string
        sprintf(voltage_str, "Voltage: %.2fV", voltage);

        // Display voltage on LCD screen
        LCD_DrawString(10, 10, voltage_str, RED);
    }
}

void ADC_Configuration(void)
{
    ADC_InitTypeDef ADC_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    // Enable ADC1 clock
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

    // Configure PA0 as analog input
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // Configure ADC1
    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

    // Configure ADC1 channel 0
    ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_7Cycles5);

    // Enable ADC1
    ADC_Cmd(ADC1, ENABLE);

    // Calibrate ADC1
    ADC_ResetCalibration(ADC1);
    while (ADC_GetResetCalibrationStatus(ADC1));
    ADC_StartCalibration(ADC1);
    while (ADC_GetCalibrationStatus(ADC1));
}

void LCD_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    // Enable GPIOA, GPIOB, GPIOC and AFIO clocks
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB | RCC_APB2Periph_GPIOC | RCC_APB2Periph_AFIO, ENABLE);

    // Configure PA5 (SCL) and PA7 (SDA) as alternate function push-pull
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_7;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // Configure PB0 (RESET) and PB1 (DC) as general purpose output push-pull
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOB, &GPIO_InitStructure);

    // Configure PC13 (CS) as general purpose output push-pull
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOC, &GPIO_InitStructure);

    // Initialize LCD screen
    LCD_Init();
    LCD_Clear(BLACK);
}

接下来，我们在主循环中获取ADC值，将其转换为电压，并将电压值显示在LCD屏幕上。

在这个例子中，我们使用了LCD_DrawString函数将电压值显示在屏幕上。您可以根据需要更改此函数，以便在屏幕上绘制图形或其他元素。

请注意，此代码仅适用于基于stm32f103的系统，而且未经过完全测试。在使用此代码之前，请务必仔细阅读代码并进行必要的修改和测试。
