I need to enable DAC in B-072 LRWAN1 in End Node example. I've included the HAL drivers and initalised the DAC . But I can't get the DAC Output on PA4 .

See if you can drive it high/low as a GPIO

Seem to recall it potentially conflicting as a pin on the SX1276, or configured as an ADC elsewhere.

You'd probably want to use a debugger, and decompose the RCC, GPIO and DAC settings to confirm the mode the pin is in

Thanks... I figured out I hadn't included the dac_ex.c file.. It works now
