Each appears to function on its own, but when I try to use them in tandem, the e-paper shield stops functioning. The light shines green on the shield, but nothing updates. I can still use the bluetooth shield just fine.
Are these shields incompatible? The one thing that I do notice is that the ICSP headers on the Arduino Uno are not picked up by the bluetooth shield, as the antennae is in this spot. The e-paper display does have a female end for the ICSP headers. Could this be the issue?
Any help would be greatly appreciated. I like both of these products, and I’d love nothing more than for them to work together.
Yes, your surmise is right, the small e-paper shield need ICSP port connected to Arduino, so if you plug e-paper shield onto Bluetooth Shield, the e-parer shield can’t work.
By the way, the e-paper has occupied almost all digital and analog pins,include digital 3 to digital 7, so if you wanna use them together, the bluetooth shield need to use analog 4 and analog 5 as the software serial pins.
More detailed information you may refer to the schematics of them.
I could really use a response here. I understand how to set A4 and A5 as the SoftwareSerial pins. However, I have no idea how to get that to work with the board. There are no jumpers for A4 and A5. Would I need to fashion some jumper wires to go from the Grove input tied to those two ports out to the BT_TX and BT_RX jumpers?
Thank you for your response! I have looked into that, but remember that I will have the e-paper shield sitting on top of the Bluetooth shield. The e-paper shield has no female headers that I can use, and the headers for the Bluetooth shield will be occupied by the e-paper male pins. That is why I was considering using the Grove connector. The other issue is the low clearance with the other board. I may have to fashion some sort of intermediate breakout board between the two. I still have to figure out how to reroute the ICSP pins anyway.
