Write-only ATTINY programming through UPDI? (feddit.de)
 

I have a design that includes an ATTINY424 doing simple logic functions / I2C monitoring.

From my understanding UPDI is a half-duplex UART. For simple factory programming (no verification or debugging needed), do I need the RX side of the UART or can I just bit bang the programming sequence through a single open-drain I/O of another processor and ignore all responses? (Using an external FET to protect the processor from the possible 12V pulse of an external POD if I decide to use one at some time) Does anyone have experience with that?

Verification is not required since the functionality of the ATTINY will be fully covered by the HW test.

Free Course Recommendation: The Medieval Icelandic Sagas by the University of Iceland on edX (www.edx.org)
 

To get started with reading the sagas I can recommend the free course on edX. It gives an introduction into the history of the icelandic sagas and introduces a lot of primary and secondary sources. I took the course a year ago and it helped tremendously.

Nice! Thanks everyone. I'll be trying the redirector addon the next few days. Noticed something cool. On this post we've got interaction from at least 4 different federated lemmys

  • feddit.de
  • lemmy.ml
  • kbin.social
  • beehaw.org

I quite like this new world.

Trying hard! What I'd need is a browser extension (Firefox) that just sends me to the fediverse as soon as I type "old.reddit.com" into the address bar to kill some time. Old habits die hard.

Always knew I was destined for hell.

  • Professionally I mostly work with C (no ++) for bare metal micro-controllers. Basically I'm using it to tie together HW peripherals with some communication library.
  • Python is my one-size fit's all tool for anything that has an OS. Testing, scripting, interfacing, it does it all.
  • I also used to work a bit with Erlang, which is my personal favourite programming language for its pure elegance and resilience.

Bei mir ging das sofort. Mal schauen obs was wird. Reddit arbeitet ja verschärft am eigenen Untergang.
