Re: Communicate with secondary chip

Trying to figure out how to get full-res copies of the photos... I'll try attaching them non inline. Edit... That doesn't seem to have worked either. Here they are on my website: https://david.zemon.name/downloads/esp8266_to_prop.png https://david.zemon.name/downloads/esp8266_to_prop_super_busted.pn...

Re: Communicate with secondary chip

Okay... this has been an interesting day of messing around with I2C. I'm guessing the problem is that I have two bit-banged I2C routines, neither one matches specifications perfectly, and together they're doing terrible things to each other. Setup Broken: Parallax Propeller running a bit-banged I2C ...

Re: Communicate with secondary chip

Propeller only has 32kB of shared program/data storage, so micropython on that end is a no-go. I guess what I meant by "does not do ... well" was "can't handle high speed". But I guess, like all things related to performance, I should probably start with what's easy (using that I2C driver I have) an...

Communicate with secondary chip

I'd like to have two-way communication between my ESP8266 and a secondary chip (Parallax Propeller) which will be in charge of real-time work. I've been having a lot of fun with the ESP so far and testing various features, but the one thing I'm struggling to figure out is how my two chips will commu...

Re: CAN bus implementation

That's great news! I have not tried it. Looking forward to hearing from someone with the hardware that can confirm it works

Re: CAN bus implementation

I'm afraid I haven't touched it since my last post. I've picked a previous personal project and have been working entirely on that.

Re: Dammit! Wrecked my Pyboard already.

Very sorry to hear this :( I definitely fried my share of electronics in the last few years. Good luck getting a new one

Re: Developing your first pyb module:

Didn't get much further tonight, but I did improve on the format a lot and added a bit of content. Should be much easier to read going forward. Work will be very minimal for the next several days. I have plans this weekend and preparations to make :) (Anyone here familiar with TSD rally?! 8-) :mrgre...

Re: Developing your first pyb module:

That stuff is gold, thank you! Most of that I've done and was going to type up tonight, but the dynamically allocated object was something I hadn't yet figured out (and really wanted).

Re: CAN bus implementation

I'm not sure what kind of officiality you're looking for - if you mean part of the pyboard module, then that's exactly what I'm working on. I am working to add source code to the micropython project, not just an independent library/add on. If you want to see the current progress, check out this thre...
