I purchased a Seeeduino Stalker board and the 2.8" TFT shield, and I’m trying to add a SHT11 temperature/humidity sensor to this combo.
The first problem is to find an available pin, because the TFT shield seems to use ALL of the pins.
Except for two: pins 18 and 19 (SDA and SCL).
So far so good, I get the SHT11 working, I can read temperature and humidity and display it on the TFT.
Next step is to get some data from the DS3231 RTC. Problem: when I initialise the communication to this chip, the temperature data from my sensor gets completely scrambled…
because I am using the SDA and SCL pins?
Am I right that you can’t use any other sensor if you use this TFT shield? This would be a major setback for me,
Thanks for any info or input,
