DS90UB928Q-Q1: GPIO support PWM,I2C control

Part Number: DS90UB928Q-Q1


Hi

DS90UB928Q-Q1, does GPIO support PWM? How much frequency can it reach?

Soc I2C controls 928 through cable, connected to display,

Is that possible? Are there any problems or risks?

thanks！

    Hello Neal,

    Yes, this is possible.

    In the 928 datasheet, section "7.6 AC Electrical Characteristics", there is a minimum pulse width requirement for GPIOs, for forward channel and for back channel. Make sure you are meeting that min requirement when configuring your duty cycle.
