I had seen the post about clocks. As I had the module it I thought I may as well use it as I don't have a crystal to solder onto the Espruino.

I setup the I2C
```
I2C1.setup({scl:B6,sda:B7}); 
```
Then tried
```
I2C1.readFrom(0x68,1)
```
The interpreter returns
```
INTERNAL ERROR: Timeout on I2C Read Receive Mode
INTERNAL ERROR: Timeout on I2C Read Receive
INTERNAL ERROR: Timeout on I2C Read STOP
```
What am I doing wrong?
