Capacitive Fingerprint Sensor with I2C and ESP32 | SEN0359
Alessio1840 2023-02-06 21:56:59 1039 Views3 Replies Hello everyone, i have bought the Capacitive Fingerprint Sensor SEN0359 with I2C module for arduino.
I use an ESP32 and I also downloaded the <DFRobot_ID809.h> library
I tried to make esp32 work with the program: Sample Code 1 - Get Module Information
Unfortunately the program crashes at the "finger.begin()" function.
Do you have any idea how I can solve the problem?
Unfortunately still no progress with my ESP32 :-( maybe somebody could help?
Günter.Keilhammer Hi,
i just started today and have the same issue. It's not really crashing - it's just “stopping” there. I also used sample code 1 for getting module information. But any other code isn't working as well. The same code on a NodeMCU with ESP8266 is working as expected just to do the double check.
Scanning the I2C Bus with ESP32 is finding the device at 0x1F so it is present at least.
Best Regards,
Guenter
Günter.Keilhammer Hi
Could you please share a screenshot of your crash information? That can help us diagnose the problem.
Chances are that the I2C pins of ESP32 are different from that in Arduino, maybe you have to change it according to your board's data sheet.
Hope that can help.
