Re: Needed additional pins for PSRAM

Hi q2222ch, Are you sharing the SPI channel for the internal FLASH ESP32-D2WD with the ESP-PSRAM? For connecting an external ESP-PSRAM with ESP32-D2WD using the same SPI channel, are you connecting the PSRAM as follows; GPIO8(psram_d) ,GPIO17(psram_q), GPIO7(psram_wp), GPIO11(psram_hd) and then use ...

Re: how to use esp32 input capture and motor pwm function?

There are two drivers in progress for driving the motors : Basic PWM (bpwm) and MCPWM (Motor Control PWM) . They will feature on the fly frequency and duty changes, they will have sync, capture, fault & dead-time subunits and will also be able to generate the signals for driving bridge driver circu...

VDD_SDIO for ESP32 D2WD

Hi,

Is VDD_SDIO set to the voltage required by the internal flash of the ESP32-D2WD? Is it a 3V3 memory?

Re: how to use esp32 input capture and motor pwm function?

We also have an application which requires motor control and are evaluating the ESP32 for that function. Would be great to take a peak at the motor PWM.

Is it possible to provide some early information?
