Interfacing mIKROE-4752 with ESP32

[AyazAhmed]

Dear Team,

I have interfaced MIKROE-4752 (Touchpad 4 Click) with ESP32 and connecting to the Bluetooth device via HID

I have used example code for the ESP32 compatible with Azoteq IQS7211A touchpad controller in the website as mentioned below.

The Touchpad 4 click is not sensing the movement on the touchpad properly so we are not getting desired output. Below is the sample video related to the sensing the movement on the touchpad panel.

Please let us know what may be reason for the not happening the sensing properly and suggest us the necessary steps to be carried out to resolve the issue.

Hi,

We haven't interfaced Touchpad 4 Click with ESP32, so I don't know what is the exact issue here, but since it uses I2C communication - can you ensure that the I2C is working on your host board ?
If so, are you using the correct I2C device address in the code ?

Regards,
Filip.

Hi,

I have checked the I2C in the host device that is ESP32, and it is completely working fine.

As per the datasheet the I2C device adress is 0x56. Please find the reference imgae for the reference.


The response time in the touchpad is more. The response is not replicated parallelly as there is some delay and touchpad is not responding for the movement in the touchpad.
