Based on RASC-based keil electronic clock production 8_ button to modify the digital tube time
overview
In the previous courses, the digital tube and RTC have been driven separately. At the same time, the digital tube has been integrated to display the specific time, but the time cannot be modified. In this section, we will configure the use of buttons to modify the specific date.
hardware preparation
First, you need to prepare a development board. Here I am preparing a development board with chip model R7FA2E1A72DFL:

keil electronic clock production based on RASC (Renesas RA)----(8) button to modify the digital tube time
Configure button pins
The corresponding pins of the buttons here are as follows.
Configure the pin as input mode, and add a pull-up at the same time, so that the default level is high level, and the corresponding pin is low level when the button is pressed.
Key setting
You can use the R_IOPORT_PinRead() function to read the level status of the IO port. This function can only read the level of one port.
Define a variable to save the key state.
bsp_io_level_t sw1;//按键SW1状态
bsp_io_level_t sw2;//按键SW2状态
bsp_io_level_t sw3;//按键SW3状态
bsp_io_level_t sw4;//按键SW4状态
bsp_io_level_t qe_sw;//触摸电容状态
int sw1_num1=0;//按键SW1计数值，去抖和长按短按判断
int sw2_num1=0;//按键SW2计数值，去抖和长按短按判断
int sw3_num1=0;//按键SW3计数值，去抖和长按短按判断
int sw4_num1=0;//按键SW4计数值，去抖和长按短按判断
int qe_sw_num1=0;//触摸按键计数值，去抖和长按短按判断
void qe_touch_sw(void);
//数码管显示状态，0正常显示，1修改小时，2修改分钟，3保存修改数据，4温度，5湿度
int smg_mode=0;
int sec=0,min=0,hour=0;//保存时间数据
uint16_t time_mode_num=0;//定时器刷新时间，实现闪烁效果
Define the while loop of the main program to execute once every 10ms, which is convenient for key reading and time setting.
R_BSP_SoftwareDelay(10U, BSP_DELAY_UNITS_MILLISECONDS);
Add variable definition in timer_smg.c.
//按键变量
extern bsp_io_level_t sw1;//按键SW1状态
extern bsp_io_level_t sw2;//按键SW2状态

Set to press the sw1 button for 1 second to enter the next mode, sw2 to modify the time hour and minute downward, and sw3 to modify the time hour and minute upward.

Add this function in timer_smg.c.
At the same time, it needs to be declared in timer_smg.h.
void set_smg_button(void);//处理数码管显示,当前状态修改
Since we need to modify our RTC clock value, we need to introduce a structure that defines RTC.
extern rtc_time_t set_time;//RTC时间定义
After the modification is completed, the digital tube can be flashed in the timer to remind the user.

R_RTC_CalendarTimeSet(&g_rtc0_ctrl, &set_time);
smg_mode=0;
}
num_flag++;
if(num_flag==5)
num_flag=0;
}
}
When the initialization is complete, we need to save the time data.
sec=set_time.tm_sec;//时间数据 秒
min=set_time.tm_min;//时间数据 分钟
hour=set_time.tm_hour;//时间数据 小时
In the main program, whenever the second is 0, save the minutes and hours data to min and hour, which is convenient for reading when setting the time and updating to the RTC after setting the time.
if(rtc_second==0&&smg_mode==0)//这个时候刷新变量
{
sec=rtc_second;//时间数据 秒
min=rtc_minute;//时间数据 分钟
hour=rtc_hour;//时间数据 小时
}
Add key processing function in the main program.
