DWIN库是基于MIT开源协议的dwin串口屏幕快速开发库. 该库需要工作在RT-Thread(后文简写RTT)物联网操作系统上, 整个DWIN库基于RTT底层设备层框架进行开发, 只要支持串口设备的RTT BSP都可以直接env在线安装DWIN库.
代码:
#include <rtthread.h>
#include <dwin.h>
/* 页面 */
#define PAGE_NUM 2
dwin_page_t page[PAGE_NUM];
dwin_num_input_t input;
dwin_button_t login;
dwin_qrcode_t qrcode;
dwin_gbk_t gbk;
dwin_icon_t icon;
static void input_callback(rt_uint32_t value)
{
rt_kprintf("User input password is %.8d.\n", value);
}
static void login_callback(void)
{
rt_kprintf("Login.\n");
}
int main(void)
{
rt_uint16_t index = 0;
for(index = 0; index < sizeof(page)/sizeof(dwin_page_t); index++)
{
page[index] = dwin_page_create(index);
}
/* 全局控件 */
gbk = dwin_gbk_create(DWIN_ALL_PAGE, DWIN_VAR_ADDR(0x000), 100);
dwin_gbk_show_string(gbk, "你好不好呢ppp呢");
/* 页面0 */
qrcode = dwin_qrcode_create(page[0], 0x0300, 100);
dwin_qrcode_show_url(qrcode, "https://github.com/liu2guang/dwin");
icon = dwin_icon_create(page[0], DWIN_VAR_ADDR(0x400), 6);
dwin_icon_set_index(icon, 5);
/* 页面1 */
input = dwin_num_input_create(page[1], DWIN_VAR_ADDR(0x0034), input_callback);
login = dwin_button_create (page[1], DWIN_VAR_ADDR(0x0038), login_callback);
return dwin_run(0);
