Hello Jim, please find here my observations. Since I received back the unit, it works fine. I have to agree that the root cause of the problem was from my side! I first discovered that there was two resistors into your original package! I was using 4.7KOhm resistors, but yours are only 470Ohm. Then I observed something strange: - If I plug the UNO to the usb port before I launch the Aby olcanut - Serial & I2C Devices
Hello Jim, thanks for your time. I was using this device for several hours testing the app I'm currently developing. It was working fine with sometime the need to reset the Arduino to get the correct display. Because I was using a breadboard, I though this was due to bad contacts. Then I produced a pcb in order to eliminate the bad contacts, but it was definitively not working. That's the rby olcanut - Serial & I2C Devices
Hello Jim, can you run a test using an Arduino (UNO) and one of the example from the library? This was also not working. Olivierby olcanut - Serial & I2C Devices
Hello Jim, BV4618 left Germany on yesterday by post.Please let me know what will be the result of your investigation. Olivierby olcanut - Serial & I2C Devices
Hello, I tried the factory reset, but no effect!! I still get only the I2C addressby olcanut - Serial & I2C Devices
I just got the same problem than Brian! I'm also using the BV4618 with an Arduino UNO and succeed to use it for a couple of days. Now I see only "I2C 0x62" on the display. Shall I also send you back the module? Thanksby olcanut - Serial & I2C Devices
