ESP8266: Say ‘hello’ to Frankenstein

Since I’ve got some homebrew development boards ready, it’s time to get hacking.
I stocked on coffee and gave esp8266 SDK a deep dive this weekend. The code is really weird, lots of things are unknown, API is shitty, blobs all around the place. First of all, to make things clear – I’m not going to fix or do anything with AT-command firmware. It sucks. Period. Sucks so much it can’t even prove useful as a reference most of the times. So… we need a replacement.

This is what I’m working on and that is now, after a weekend of hacking is in early alpha stage.

Say hello to Frankenstein Firmware for ESP8266.

rf24boot v0.2 released!

DSC_0078

It was a busy month, but I finally managed to find a minute and update the rf24boot. Yes, the very thing that can push firmware updates via nRF24L01 wireless modules. Along is a regular bunch of updates to rf24 library in antares. One of the big news I finally took some 20 minutes and layed out a proper programming dongle. Since I didn’t have a cheap stm32 with usb around, and stm32f103ret6 looked like an overkill for this purpose this dongle still uses avr, vusb, but has a 16M (20M is possible as well) crystal. The lengthy changelog’s under the cut, but it’s big.

Antares 0.2-rc1 released!

That’s it! It’s out. After two years of slow and steady development in my free time. Antares is a free and open source (GPLv2) buildsystem bundled with library code, aimed at bare metal targets. Sounds scary? Well, consider this an arduino for kernel hackers. If you are one – you have all the regular tools here: kconfig, GNU/Make, and no need to write Makefiles from scratch or collect sparse instructions over the web – just bootstrap a project, adjust the config to your needs and go!
0.2-rc1 is the first release that can be considered (more or less) stable for every day use. To find more about what it is and how it works – check out the README in Russian or English

stcdude 0.1-rc1 is here.

Well, that was fun, and I can now finally show off with the first release of the stcdude.
stcdude is an opensource ISP programmer for the STC microcontrollers designed to run under linux from commandline. A long awaited sane replacement for the retarted STC ISP Tool written in VB6.
Finally you can get on with the development using the tools you like: sdcc and make.

STC 8051: Some research notes

I picked up a bunch of those uCs + a dev board quite some time ago. I even did some initial digging, but due to the lack of free time postponed any work on them. These uCs may not seem that tasty as stm32, but are still quite powerful and dirt cheap. (If you want to flood the market with something).
