Does anyone know how to write to the analog pins of the Arduino attached to the PYNQ Z1 ?? Im trying to control the power of a DC motor. I also try to send instructions to a Servomotor but I have no response. Thanks!

The Zynq chip in the Z1 has an ADC connected to these pins, so you can only read analog values, you can’t write them. If you want to write analog values you need a separate DAC. You could get a Pmod DAC; example here: Xilinx/PYNQ/blob/master/boards/Pynq-Z1/base/notebooks/pmod/pmod_dac_adc.i…

Hello @Susana,

This post PWM on PYNQ_Z2 to a motor may answer your question.
