A quick note – I have made all of my sites secure (https://) and so the original OTA site for my ESP8266 ROMS (www.scargill.net) is no longer appropriate. roms.scargill.net is now the place to go (which redirects elsewhere and also has a pretty interface) – sorry for any inconvenience. The files are not seen if you visit the site, just a home page - you simply enter the name of the site followed by slash and the rom name - for example... roms.scargill.net/rom.bin
Files available are:
blank.bin and esp_init_data_default.bin are needed for utterly blank ESP12 units.
rboot.bin and rom.bin are for my new ESP8266 code (which no longer supports ESP-01)
rboot.bin and romx.bin are for my older ESP8266 code (no longer developing that version but it is fine and might run fine on an ESP-01 without OTA)
I have to say, it felt a little like Christmas today when the Correos post-lady turned up with a plastic container full of packages from China for me.
Among the many items in today’s post were the two you see above – a WEMOS board (i.e. ESP-12 + power supply) which includes an OLED display. As you’ll know I’ve recently added the SD1306 display to the commands on my ESP8266 code – looks like they’ve done the same but gone a stage further and added the actual display to the board.

I just learned something new!
ONLY of interest if you are using Node-Red and will lead to a description of the new node-red-contrib-diode node.
If you are into Node-Red – you really want to see this one…

What a week this has been. Firstly apologies to everyone seeing 404 errors yesterday.
It turns out it was an issue with settings on the LightSpeed servers the provider is using…
I’ve had no end of issues with them… but hopefully this is now resolved. Meanwhile I’ve been doing a little more work on my Nano-base peripheral… read on..

I recently completed some work on the 240*320 ILI-based boards on my kitchen-sink ESP8266 code which is designed to work with the home control system but basically is an ESP8266 board that responds to MQTT commands.
I’m very pleased with the display code but it came to my attention that the price has gone up recently – £4 - £7 depending where you go. So having completed some work on the tiny but beautiful 128x32 OLED displays which are DIRT cheap, (see also the 64 pixel versions) I thought I’d revisit the ESP code which already supports a number of I2c peripherals including my new Nano peripheral – and added in the SSD1306.

As the blog entry on using my home control code ROMS for ESP8266 is filling up and of course as much of the information is now dating I thought I’d do a new blog to bring everyone up to speed and move the conversation to this blog entry. The good news is - the code is now running under SDK 2.1.0 – i.e. bang up to date at the time of writing.
Firstly – yes, everything works – but the procedure for flashing ESP-12 etc has changed ever so slightly. I have updated the binary files to run on Espressif SDK 2.1.0 and updated the RBOOT code I use for OTA (over-the-air updating) to the latest version.

Some time ago I tested Mongoose OS, early days and I had a lot of difficulties. This blog is a partial re-write because I see no reason to leave information lying around that is well out of date – there is a lot of that on the web already – and the current setup is MUCH easier to use than before. I have to tell you that the version changed as I was writing this so make sure you have the latest mos.exe
