Re: Discontinued? Current "official" power supply for Pi's 1-3?

I don't believe the older supply is being discontinued, however, we may simply be replacing it with the new one and an adapter - will check. Note the new design is better than the older one anyway - more efficient, less plastic waste - so it's a better option anyway. Thank you James, I would apprec...

Well it seems a different supplier is only a temporary solution to the supply problem it’s discontinued by the foundation.

Hence the question. Is the foundation discontinuing it?

Discontinued? Current "official" power supply for Pi's 1-3?

Newark is telling us the official power supply offered by the foundation is being discontinued? Specifically, the micro USB version needed for Pi 1, 2, 3.

Is this true? If so, why, and what is the recommended replacement?

Re: Setting register bit

But you must write a byte...which I thought was the obvious point of my post. The OPs code included a single value for the data portion of the i2c message as he thought he could write a bit.

Re: Setting register bit

Benno,

You're not going to be able to just write one bit, the smbus "write_byte_data" method expects you to write at least one byte...hence the name of the method. Furthermore, it looks like your device expects more than one byte.

Re: Interrupt from PICAN2 does not work

Thank you for your answer. Yes, this should be done using an Rx interrupt, as each message should be evaluated as soon as possible. Furthermore, the whole thing should be realized in C/C++, because I want to build a GUI with CodeBlocks (wxSmith) later. How fast do you need to process the messages? ...

Are you sure you want to use an interrupt? I've had quite a bit of success with the PICAN2 hat, but was interfacing it with Python via the python-can module. The buffered reader in that class works great...you'll just have to filter out the messages with the ID you want. https://python-can.readthedo...

Re: Will there ever be other official display sizes?

I think a 10" would be nice, but also think a 5" would be nice.

For those that know...what is so unique about the dsi connection that keeps other mfgs from providing displays using the same interface? Maybe there is another reason?

Re: General approach to continuous i2c device register reads while not blocking user generated writes/reads

I've somewhat concluded that each i2c read or write should go into a queue in this scenario, and hopefully I can configure things such that any user generated read or write immediately goes to the top of the queue.

The reason is that you are using an SMBus library to write to an I2C device. SMBus != I2C. http://www.ti.com/lit/an/sloa132/sloa132.pdf and https://en.wikipedia.org/wiki/System_Management_Bus SMBus is a protocol on top of what looks close enough to I2C to work in many cases.
