{
CLK_PeripheralClockConfig(CLK_Peripheral_DAC, ENABLE);
RI->IOCMR2  = 0x10;
 RI->IOSR2    =0x10;
  DAC_DeInit();
  /* Fill DAC Init param DAC_Trigger_None   and  DAC Channel1 Init */
  DAC_Init(DAC_Channel_1, DAC_Trigger_None, DAC_OutputBuffer_Disable);
  /* Enable DAC Channel1 */
  DAC_Cmd(DAC_Channel_1, ENABLE);
  DAC_SetChannel1Data(DAC_Align_12b_R,2048);
}
stm8l dac  此程序已经在stm8l152c6t6上面验证过,测PF0可以有正常的输出。但是在STM8l151K6上面测PB5引脚确没有输出。问题会是在哪里?左边为stm8l151.右边为stn8l152
经高人指点要设置routing interface.可是加了 
RI->IOCMR2  = 0x10;
 RI->IOSR2    =0x10;仿真的结果显示这两个寄存器任为0.本人菜鸟。希望大师进一步指点;谢谢!!!
