![]() ![]() This make the communication not byte to byte controlled as I want it to be for my need. I realized that if I wanted to make an Arduino slave, when receiving from master, it actually reads from a buffer that is already previously received. This Arduino library abstracts away all of the low-level I2C communication, so you can easily initialize the fuel gauge then read voltage, state-of-charge. Place a jumper wire between REC and GND pins. Place a jumper wire between the REC and GND pins on the board, then press the reset button. Connect the board to your computer via USB. They may throw away the register value from the initial write, so the subsequent read won't work. For these devices, a STOP is seen as sort of a 'reset'. What's the Issue Some devices require a repeated start. ![]() This can be solved through the following steps: 1. The answer is target device specific and would be found in the target device datasheet. But let’s start with the problem found in the Wire. The following online databases require authentication. Sometimes the board is not detected even when the board is connected to your computer. When the limitations were somehow fixed, even though the small number of modifications (it is somehow a sort of hacking of the library) I found that the my final result were so useful to me that I thought was worth to write a short article about it. Then, when experimenting with a portability of a project in the Arduino environment, I started to trying the official Wire library, discovering some incompatibilities for my needs. I have spent a lot of time on playing and later working on the I2C buses. I almost always used self developed libraries, both for learning and job requirement purposes. ![]()
