你好，将rom_i2c_writeReg_Mask放进初始化函数后问题已经解决，红外发射基于38k载波，提供的示例占空比为1/2,能否提供一个调节频率和占空比的函数，可以供开发者自定义频率和占空比。

找到异常原因，只有工作在station模式下会崩溃，AP模式没有问题，AP+STATION也不会有问题，期望尽快修复啊，应该算是BUG了吧，，，，

rom_i2c_writeReg_Mask会导致系统崩溃？？？

2016-03-25T18:38:50+08:00

定义如下，调用rom_i2c_writeReg_Mask后连接wifi，会导致系统崩溃问题，sdk版本v1.5.0

Code:

#define i2c_bbpll                           0x67
#define i2c_bbpll_en_audio_clock_out           4
#define i2c_bbpll_en_audio_clock_out_msb       7
#define i2c_bbpll_en_audio_clock_out_lsb       7
#define i2c_bbpll_hostid                      4
rom_i2c_writeReg_Mask(i2c_bbpll, i2c_bbpll_hostid, i2c_bbpll_en_audio_clock_out, i2c_bbpll_en_audio_clock_out_msb, i2c_bbpll_en_audio_clock_out_lsb, 1);
