Discussion - Software / Re: FT813 How to check Touch Interface communication status
« on: September 02, 2020, 07:56:24 PM »
It is not feasible to have additional I2C lines to the CTP as I don't have an I2C bus/connection available.
I wanted to clarify if EVE checked the status of the I2C connection or simply listened for touch responses, if it is only listening then I will not be able to verify which CTP is connected, if the hardware team can verify that would be really useful.
The only alternative I have is to use one of the USERID bytes on the dsPIC I'm using to specify the I2C address and to set this when uploading/programming the code, then my application can read this byte and initialise the display correctly.
Regards.
