STM32L432 Nucleo DAC1 Out2

[CJaro]

HI,

First time user stm32l4 nucle and I struggle to get DAC1 out2 processor voltage (using CubeMX and HAL). Is my problem due to bridge 18 of A4 and D4 or there is something wrong with stm32l432?. DAC1out1 works as programmed but not out2. As A4 and D4 shorted I try to setup D4 as Analog or GPIO Digital In , still not getting Out2 signal. Do I need to dummy clock D4 or remove bridge18.

What is "dummy clock"?

I guess removing the bridge is a sure option; however, PB7 which is on the "other side" of the bridge at D4, should be by default in Digital In state, which is almost high impedance.

Read out and check the relevant GPIO and DAC registers' content.
