I receive a blank i2c address map. When I first tried the circuit it worked fine using a breadboard. At some point it i2c-tools became unable to recognize any i2c device unless I hook that device's data and clock line directly to the RPI3. I verified this issue using kernel 4.14.18-v7+ using Stretch.
Code: Select all
i2cdetect -y -r 1
I eventually went from i2c based projects to SPI based projects. Could switching from i2c to SPI have caused something to fail?
My problem is a duplicate of this https://raspberrypi.stackexchange.com/q ... i2c-device
I"m using a ribbon cable https://www.amazon.com/gp/product/B074D ... UTF8&psc=1 to connect the GPIO headers to a breadboard. Could parasitic capacitance or inductance be the problem here? If so how would I verify this?
Any help would be appreciated. Thank you.
