ESP-8266EX Soil sensor (chirp!) I2C problem
Posted: 05 Jul 2020, 15:56
Hello!
I tried to connect a chirp!-sensor to a wemos d1 mini using espeasy 20200703 (dev).
This is the sensor: https://wemakethings.net/chirp/
My problem: I can not get the I2C connection working. With various other devices the I2C connection is working perfectly. But connecting the chirp!-sensor not even brings a result in the I2C-Scan.
I tried two devices (display and chirp!-sensor) in the I2C-bus: the display is working well stand alone. As soon as the chirp!-Sensor is connected to the I2C-bus, the I2C-scan does not work any more.
Is there a "real" I2C-bus in the chirp!-sensor? The chirp!-sensor uses a ISP-bus:
pin 1 - MISO
pin 2 - VCC
pin 3 - SCK / SCL – I2C clock
pin 4 - MOSI / SDA – I2C data
pin 5 - RESET
pin 6 - GND
I connected VCC (3.3V) and GND. I2C: pin 3 and pin 4
Any suggestions??
Thanks a lot for your reply!
best regards
Michael
