Re: MicroPython Newsletter Issue 1

Argh! So freakin' excited about micropython board with BT/WiFi radios out of the box!!! Available within "the next few months"? I know it's probably hard to say, but can you be more specific?

Re: machine.I2C and the stop condition

The AD5933 measures the complex impedance of the load. I cannot disclose what I use it for specifically in this case, but one use-case is laid out on p. 32 of the datasheet.

I like the chip, as it has almost everything on-board, with minimal post-processing required.

Re: machine.I2C and the stop condition

Ahh! Great explanation – will keep that in mind when reading the docs :-)

Thanks again. I have now built my very rudimentary AD5933 driver. When it has been expanded and tested, I will share it .

Re: machine.I2C and the stop condition

Dear @deshipu, Thanks for commenting on this. I see that using false as a third and keyword-less argument works! Is the documentation wrong, or do I not get the finer points of how it is documented? Thank you for your time! See working code at the bottom. Using primitive operations Not supported on ...

Re: machine.I2C and the stop condition

I have implemented a solution where I read and write a single byte at a time. This works for now, but for a later version I would like to read and write larger blocks in one go, so I am still interested in this topic :-)

machine.I2C and the stop condition

I am trying to communicate with the impedance converter AD5933 through I2C. However, it seems that Analog Devices have adopted their own flavour of block reading and writing, cf. the datasheet p.27-29. Using the machine.I2C library, I have not had success reading and writing blocks. I have checked, ...

Re: Ideas for next evolution of pyboard

What about having a cellular modem on-board? LTE CAT-0 would be a really first-mover thing to do! If you talk to Gemalto (they seem pretty forward on this, using Sequans chipset). Also Altair is making chipsets for CAT-0, but I don't know of anyone making modems with it yet!? Maybe a partnership tha...

Re: Step-by-step guide to putting micropython onto STM32F405

ad 1) I would love to get the DigiKey ID (or any other identifier) on the key components! Will post them here for others to use as well? ad 2) I will make sure to copy the pyboard in this respect. This is really exciting. I'm on vacation next week, but I hope to get back to it soon after. Thank you ...

Re: Step-by-step guide to putting micropython onto STM32F405

Thank you for all this info! It is really helpful. Why is it that you want to create a custom board? It seems prudent to become familiar with the MCUs by using an existing board, rather than trying to create your own. Haha, yes it seems crazy! I have played around with the pyboard(s) for a long time...
