This board doesn't support AnalogOut, why ?
Hi, I need the DAC (AnalogOut) function for reference voltage, why does this board not implement ? Thanks.
Update 171017
So far, I implemented my own version as following code, but I think is not a good way.
DAC output
void dac_output(uint32_t mv) {
PlatformMutex mutex;
mutex.lock();
/* Enable DAC clock */
CLK_EnableModuleClock(DAC_MODULE);
/* Config PB0 as DAC output */
SYS->GPB_MFPL &= ~SYS_GPB_MFPL_PB0MFP_Msk;
SYS->GPB_MFPL |= SYS_GPB_MFPL_PB0MFP_DAC ;
/* Internal Vref 3.072V */
SYS_UnlockReg();
SYS->VREFCTL = (SYS->VREFCTL & ~SYS_VREFCTL_VREFCTL_Msk) | SYS_VREFCTL_VREF_3_072V;
SYS_LockReg();
/* DAC output */
DAC_T *dac_base = (DAC_T *) DAC_BASE;
DAC_Open(dac_base, 0, DAC_WRITE_DAT_TRIGGER);
DAC_SetDelayTime(dac_base, 8);
DAC_WRITE_DATA(dac_base, 0, ((4096UL * mv) / 3072));
mutex.unlock();
}

Easily the mapping you expect (digital pins) this must be called prior to any I2C reads or writes before the program can operate be transformed into e difference is that analog write with pin D5. Or use to many different platforms.
