Yesterday, I have worked on the I2C communication with the capacitive sensor controller.
I got a problem because I received a NAK when I tried to read or write a register but, thanks to Samuel, I finally solved it. In fact, the device, after receiving its address, wakes up but sends a NAK. It expects the master to retry the transaction until it accepts it.
Now, I can read and write any registers and I’m tackling with the sensor itself, by creating a capacitive button with some copper 🙂
About the wand, we had to make some changes on it, because it has been a little deformed during the last printing. It is currently being printed and we will share some pictures of it tomorrow 🙂
See you !
