Thanks Dave,

Yes, the results are always zero… I have two boards which both have the same reading. Thanks for posting the modification link though…

Regards, Chris

Chris,
are the readings actually Zero? I recall they were very low, like 47mV before the mod.
Have a look at the mod here: https://github.com/hexeguitar/ESP32_TFT_PIO#1-ldr . The change of resistor from 1M to 100K should multiply the range by 10, but I multiply that by 1000 to graph the output.

Hi.
No, unfortunately, I don’t have a guide to fix that.

Hey there,

You state in this fantastic article that “Many CYD boards require modifications to the internal circuit for the LDR to function correctly” – an actual problem that I have… (all readings are 0)

Do you have a link to this modification? I’m guessing it involves high precision soldering…

Thanks for any thoughts on this. Love your work!!!

Hi.
We’ll probably take a look into that in the future.

Greetings. It would probably be better if we used EEZ Studio.

In reply to Marcos. Check the BMP280 address. One of my modules had address 0x77 instead of 0x76. You can try changing the address in the software. What error are you getting?

In reply to Renzo.

Hi.
Currently the WoldTimeAPI is not working.
We’ll provide a new solution soon.
W’ere currently out of the office. We’ll fix this issue when we come back.

Hi SI followed your excellent lesson ESP32 CYD with BME280.
The CYD display is very interesting and allows you to view a lot of data.
Two questions:
1- I changed the 252 line but no date appears;

2- Could you also propose a solution with a GPS sensor, perhaps it would also be possible to connect it with Google Maps.

Is it possible? Thanks
Renzo
