What are you doing with Padauk chips you bought?

I know lots of people got excited about low cost chips and how that would somehow democratize embedded development. The effort to reverse engineer the tools was impressive.
However people like me actually want to make stuff with them, and it's a PITA sourcing them. I'm willing to bet most people gave up almost immediately after programming OTP chips got old. The open source tools brought out the best from the community, but there is no compatible ICE, the chips don't have a UART for serial comms, and having a full C compiler is kind of silly for a chip this limited. Let me know if I'm wrong, but I will be shocked if someone out there has used the open source tools, burning through a bunch of chips while debugging, for more than one or two trivial designs. I don't mean to disparage anyone, but I'm just annoyed that people bought up a bunch of chips they'll never use from the distributor that's easiest to deal with.

I don’t think that we anticipated the the difficulties in “sourcing” them.  They seemed to be available in bulk from lcsc, and we didn’t think that that would change.


We should have known better.  It ought to take more than brief availability from a relatively unknown manufacturer to inspire any confidence in a single-source part.  :-(

Not commenting on the rest, but this part? Who in their right mind ever thought that they would democratize embedded developement?
The whole Arduino environment did democratize embedded development. The RP2040 is also doing that great. ($1 chip this powerful and easy to use, really!)

But how anyone could ever think that a couple-cents MCU, this crippled, supported by a language that is not even C, and rather poorly documented to the point of requiring reverse engineering, would "democratize" anything is beyond me. Anyway.

Where is the option "Didn't buy because I knew they'd be a huge pain in the ass to program and debug".

Yes, my feeling on them. For me, a more interesting  question is what is the next lowest cost microcontroller which has reprogram-able flash and a decent tool-chain.
