Ok, after reading about the i2cdevice, it seems like it takes 7bit adresses, it's masking away the r/w bit, so I guess it's shifted down one bit. That means you should try 38hex instead if you put a0-a2 low and you have the A chip.
If you have the non-A chip,it would mean 20hex as adress, and then I understand the above example, and the linked example..

That's right. The Wire library used in Arduino does exactly that too. On a couple of boards I built where I had I2C slaves that supported A0..An pins, I put either jumpers or a DIL switch to allow me to set the address, but where you will only have a single device, hardwiring is usually easier. Some devices, like the RTC (DS1307?) don't support it anyway, although I'm not sure why you'd want more than RTC

And since I live in the UK, it doesn't help me much either. My day job doesn't let me pop over to the U.S. for the weekend. Mind you, since 29th just happens to be my 50th birthday, it would have been a good weekend to go....

Great! After a somewhat tiresome day at the office yesterday (and Saturday isn't a good day for that anyway), I have had a fun 20 minutes reflashing my mini devices. I am very pleased to report that it all went smoothly, and I'm now planning on doing the same with my N/N+ boards to bring them up to the latest firmware. Many thanks, Chris. SteveS

Hi SteveS,

Thanks for testing this. It might be seeing the same core issue. We'll pull it in and try to fix both at the same time.

You're welcome. I've been a software developer for 30+ years, so I know how it is. Stuff happens.

Can you use TTL for deployment for the moment?

Chris

As it happens, yes - I'll be doing some work on an N, rather than a mini for the next phase of my project.

Hi Chris

Not exactly good news. I was able to build and deploy it, but it doesn't seem to run. I have Putty running on both a USB/TTL adaptor connected to Tx0/Rx0 and on COM1 connected to DTX0/DRX0, and nothing seems to be coming out of either port.

I am going to try 'hard-setting' the transport port using the code in the selector as a guide, to see if that works.
Unfortunately it's been a busy weekend, so I wasn't able to do this yet.

SteveS

I tried setting the interface to Com1 and Com2, neither of which seem to make the RS232 port work as the transport, so I guess I will need to wait for the new firmware.
