Re: eeprom
I haven't worked with this code base in a long time but it looks like you're using two different I2C libraries to me. If you're using CPAL it seems like all the I2C function should start with CPAL_ ? What is I2C1_DEV? Doing a quick look at the functions it doesn't seem to make sense to pass in I2C1_...

Re: eeprom
Is the read during a setup/init of the I2C device or are you just testing if it works by doing a random read?
Some I2C devices need to be setup up properly before they respond, so if you just tried to read a random register it wouldn't respond.

Re: eeprom
Check for shorts near the expansion port. Either there's a solder short or one of the IC's is holding down the SCL line, which may mean the IC is dead.But SCL pin is only on around 0.04V so it looks like its shorted.
Is there a way to fix this?

The Aardvark is one. I'm sure there's cheaper ones but I like the Aardvark a lot.Che. wrote:
Do you have an example for an i2c analyser for me? I cant quite imagine what that looks like. Possibly an oscilloscope?
You can use an O-scope of course but it's very tedious work that way.

Re: xbox 360 to pc
You need a usb-to-rf dongle in order to use the xbox 360 wireless controller with a PC.
I bought a knock-off from eBay, which works OK, since the 'Official' one cost more then I wanted to spend.

Re: Power and Ground to Crazyradio
The wiki has the schematic.
The connector has 3.3V and ground.

Re: Crazyflie spins uncontrollably
It looks like you have the props reversed. What you have on M1/M3 should be on M2/M4, and then return the motor wires to match the assembly instructions.

Re: Overcharging
Yeah, it's safe, since there is an IC that manages the power and charges the battery.
