1.1 分而治之藕断丝连
还是那句话将不同模块进行封装通过变量进行模块间的合作。
1.2 模块化思维导图
下图根据题目梳理。第六届没有写这么详细主要是懒。
1.3 模块解析
整合模块逻辑思维。
1.3.1 KEY模块
B1界面12之间切换方法计数0表示界面11表示界面2。 B2三种阈值位之间切换方法计数0表示T11表示T22表示T3。 B3每次加5上限95各阈值之间还应该T1T2T3 但是我没写。 B4每次减5下限5。
//B1B4B3都是同样的格式
if(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0) GPIO_PIN_RESET) //B1{if(HAL_GetTick() - tick KEY_REDUCTION){ //按键消抖tick HAL_GetTick();keyS-bits.B1 ^ 1;
// keyS-bits.B1;
// if(keyS-bits.B1 2) keyS-bits.B1 0;while(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0) GPIO_PIN_RESET); //实现按下一次只计数一次}}
//B2多了一种状态
else if(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1) GPIO_PIN_RESET) //B2{if(HAL_GetTick() - tick KEY_REDUCTION){tick HAL_GetTick();keyS-bits.B2;if(keyS-bits.B2 3) keyS-bits.B2 0;while(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1) GPIO_PIN_RESET);}}1.3.2 ADC模块
采集可调电位器电压。默认10次为一组进行一次滤波。 假如使用0.2s时基来开启adc采集采集10次需2s响应太慢放在systick中断中程序写到后面时间1ms显短我就多使用了一个tim产生0.5s时基不用白不用。也可使用一个0.5的就行累计4次就执行一次需0.2s时基模块。也可使用dma采集。
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc)
{if(adc_smp_flag (FILTER_LEN1)){adc_smp_flag;adc_smp_vtg.smp_val[adc_smp_flag] HAL_ADC_GetValue(hadc);if(adc_smp_flag (FILTER_LEN1)){adc_smp_flag 0;filter_process(adc_smp_vtg); //累加相除}}
}typedef struct{uint32_t smp_val[FILTER_LEN];uint32_t filter_val;
} adc_smp_t;1.3.3 IIC模块
完成eeprom中数据的读写。开发板的PB6和PB7设置为开漏输出使用软件模拟实现单字节数据的读写。注意魔术棒-c\c±optimization选项要设置成-O0要不然代码执行后得不到想要的结果。 具体实现看第二部分源码。
/* 软件模拟实现at24c02单字节写入 */
void at24c02_write(uint8_t addr, uint8_t data){...
}/* 软件模拟实现at24c02单字节读取 */
uint8_t at24c02_read(uint8_t addr){...
}/* i2c向eeprom写入data */
void iic_write()
{...
}
...
1.3.4 UART模块
UART接收PC端查询码’C’, ‘S’做出相应的回应。 具体实现看第二部分源码。
//中断触发回调函数
void HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t Size)
{...
}
//定时上报数据
void uart_inform_PC()
{...
}1.3.5 LCD模块
将涉及到的数据显示到lcd屏幕上份界面1和界面2。 具体实现看第二部分源码。
void lcd_process()
{if{//1if 界面12切换清屏//2LCD显示数据//3if设置阈值成功后切换到界面1将set_thros写入eeprom}else{//1if 界面12切换清屏//2if 显示thros1为绿色设置该阈值//3else if 显示thros2为绿色设置该阈值//4else if 显示thros3为绿色设置该阈值}
}1.3.6 LED模块
这届题目我感觉难度就在led的处理上面看着题目要求非常简单正常思路当事件发生的时候使用HAL_GPIO_TogglePin()翻转led对应引脚电平就行但是我们使用到了lcd屏幕lcd屏幕也使用到PC8-PC15这些引脚所以我们每次写入led状态的时候对其他led引脚也得考虑。我就被绕进去了整了我2个多小时。还是因为逻辑思维不够强代码写少了。 三种事件相互之间保持独立。我们分析一下三个事件之间的关系 LD1每隔1s亮灭闪烁事件周期性触发。 LD20.2s间隔闪烁5次但是事件触发没有周期性液位等级变化触发一次。 LD30.2s间隔闪烁5次但是事件触发没有周期性接收到查询指令触发一次。 所以三事件相互独立可能同时触发可以一次触发其中的随机两个也可能是一个也可能是都没发生。所以这样就构成了8种情况。 我们假设一个uint8_t temp变量LD1代表第1位事件1LD2代表第2位事件2LD3代表第3位事件3对应位置1表示该事件发生需执行该事件。这样我就得到了8种情况 111代表三种事件同时发生 110代表事件3事件2发生 依此类推… 000代表都不发生。 最后根据这八种情况写入对应的电平状态就可以了。

170MHz的频率预分频值填写16重装载寄存器填写1999999实现0.2s时基 预分频值填写16重装载寄存器填写499999实现0.05s时基。 0.2s的时基用在led模块。 0.05s的时基用在uartadc上。 具体实现看第二部分源码。
