Blue pill does not have DAC in Cube

[IDavo.1]

Hi All

Today I wanted to start working with Bluepill DAC that turn out in STM32CubeIDE there is no DAC peripheral and I was shocked. Does anyone know what the h... is that issue? and how to solve it? I don't like to configure it by myself.

That is because it does not have a DAC. Who told you that it has one? Check the MCU datasheet.

Yes apparently it does not have an DAC which is really bad. In reference manual there is chapter about DAC so I thought it might have. Thanks for the answer

use a pwm with external RC filter as woraround... and change its duty cycle.. a timer will do the job.

Yeah great smart Idea.
