How to Rd/Wr data from I2C device with extra opcode (ADS7142)

We have an ESP32-S3 design using ADS7142 device from TI controlled by I2C bus. To write or read data to or from ADS7142 registers you do not only have to transmit device address and register address but also an Opcode for read/block read/write etc. which is an 8bit byte. Simply spoken to read a regi...

Re: Help setting up Espressif-IDE

Thanx for describing your workaround with 2.10 - I did it the same way and indeed it is working again.
Not sure if there are any drawbacks (e.g. newer build targets).
Might indeed change to VS-Code because of better maintenance ...

Re: Issue with http_rest_with_url function

Great and thanx a lot, indeed setting output_len to 0 unconditionally fixed the issue.

However heap size is reduced with every call to "http_rest_with_url" - is there a way to free heap whe3n leaving the event handler?

Re: Any reference example for GDEW0154T8 E-Paper LCD with ESP32 IDF

@gpteacher - thanx for your input however I assume your are referring to Arduino GxEPD2 library. We are however looking for a genuine ESP32 library / examples for e-paper display to be built with CMAKE Espressif system
