计数器

Preface

Based on the official HAL library, we can easily develop. This time, based on touch buttons and segment code display, a counter function is realized.

process

Based on LCD_TK.

Design two counters to display the upper and lower 4-digit numbers of the segment code respectively.

The return and confirmation buttons correspond to two counting inputs respectively.

Modification of App_Test function in App.c

as follows

After compiling and burning, run the program. You can see the touch button returns and confirms, and the upper and lower 4-digit counters start counting.

See video

Summarize

Based on the official HAL library, rapid functional verification and development can be carried out, which is very efficient.

After looking at it, it would be better if the code was commented as a review post, so as to make it easier for others who want to learn.

if(fu16_set_num_down>9999) fu16_set_num_down=9999;//4×ó9999

fu32_Displaydown[0]=fu16_set_num_down/1000%10;//§,LCD1(×ó)--5

It is best to modify the garbled characters like the above.

float ff_getTempHum[2];

uint16_t fu16_num_up, fu16_num_down;

uint32_t fu32_Displayup[4]={0},fu32_Displaydown[4]={0},fu32_num_123567p[7]={0},fu32_num_col[2]={0},fu32_num_s=0;

uint8_t fu8_Tkey_state = 0xff, fu8_Work_Mode=0;

uint16_t fu16_set_num_up=0,fu16_set_num_down=0;

uint8_t fu8_Hidden_point=0;//

uint8_t ret = 0;

For a writing format like this, we should also establish the format for the original poster.

It is best to post code using code blocks.

Don't simply copy and paste, this way the post may be rated higher.

I hope your next post will be more exciting.
