【Telink-泰凌微电子 B91通用开发套件】USB鼠标测试

流水源

本次测试一下USB设备。
导入通用驱动项目后，选择USB_Demo。

然后打开app_config.h配置一下。

main.c如下

int main (void)
{
#if(MCU_CORE_B91)
sys_init(LDO_1P4_LDO_1P8, VBAT_MAX_VALUE_GREATER_THAN_3V6);
//Note: This function can improve the performance of some modules, which is described in the function comments.
//Called immediately after sys_init, set in other positions, some calibration values may not take effect.
user_read_flash_value_calib();
CCLK_24M_HCLK_24M_PCLK_24M;
#elif(MCU_CORE_B92)
sys_init();
write_reg8(0x1401fb, 192/48);
#endif
user_init();
while (1)
{
main_loop ();
}
return 0;
}

复制代码

mouse_app.c初始化和主循环代码如下。修改了一下原来的例子，利用板上4个按键模拟鼠标X,Y轴。

板上4个按键是矩阵扫描方式的。见如下电路图。使用io是PC0,PC1,PC2,PC3.

编译下载

打开BDT下载软件，找到编译的固件资料。然后点Download下载。

复位板子，就可以识别到鼠标设备了。

可以通过板上4个按键，可以看到鼠标的指针移动了。
