You may have seen comments in here from Richard Burton about his bootloader. Well, I have to tell you – what a game-changer. If you look at a previous blog where I showed you how we’d moved code from the fairly normal 0x40000 starting point down to 0x20000 – freeing…

ESP8266 SDK 1.11
Just a short one for those of you who’ve not tried the new Espressif SDK update yet (SDK 1.11). I noted a pair of commands “system_param_load” and “system_param_save_with_protect” which appear to replace the need for the load and save functions that TuanPM uses in his code in /mqtt/config.c – so…
DIL Adaptor for ESP07 and ESP12
So what started me off on this journey which led to a kluge fix for the ESP SDK 1.01 (YES!!) was a parcel which appeared yesterday from Baoshi (which in Chinese means “gem stone”) containing 2 of his ESP-07 ESP-2 adaptor boards which he very kindly sent me. The boards…
ESP8266 FLASH SIZES and SDK issues
Below you will see the MAKE file used in Windows for compiling ESP8266 code for, for example TUANPMs MQTT software which I often use as a base with the Eclipse programming environment. My code is routinely compiled and run on ESP-12 boards and some time ago when I upgraded…
ESP8266 Test Board
I mentioned that Espressif were kind enough to send me a test board to play with – and very nice too. Not had time yet as I’m struggling with learning how to make an installer for my Node-Red package – with some great help from the guys involved with this….…
Presents from Espressif
Let me start by explaining that Espressif are makers of fine WIFI gadgets.. specifically they have spawned a whole new lease of life for IOT… by producing a marvellous little chip that contains a complete processor, memory and WIFI interface needing only a tiny FLASH memory chip and a couple…
Making ESP8266 Programming Easier
Updated 09 Apr 2015 – code fix: A little something here from my guest writer and friend Aidan who’s been working with me on the latest home control successes to follow after this blog! If you’ve successfully written and uploaded a piece of C code for the ESP8266 in any…
An ESP8266 for Arduino Game Changer?
(updated 2/4/2015) Here we go again – just as you thought it was safe to start coding, another game-changer comes along. This time not only do we have an Arduino IDE for the ESP8266 (which isn’t a stunningly good IDE but it’s awfully familiar to many developers) but also what…
Home Control The Next Step
As regular readers will know I’ve pretty much gotten to grips with the whole home control thing having after much research settled on a largely MQTT-based setup using the excellent new Raspberry Pi2 as a hub with Node-Red. Though it could just as easily have been any proper Linux or…
ESP826 + Pi + MQTT + Node-Red Heaven
If you’ve been following the blog you’ll note I’ve spent a lot of time getting to grips with the Raspberry Pi, Node-Red, the ESP chips using C and of course my earlier home control attempts with NETIO, the NRF24L01 boards and Arduino clones (all of which are working 24/7 –…
ESP8266 Tidy PWM
If you check out an earlier post I managed to get PWM working nicely on the ESP-12 on the otherwise unused GPIO15. Well, it was a little messy – so I’ve tidied it up with the use of a struct. Here it is.. You’ll need to make minor mode to…
ESP8266 WS2812B LEDs on a Plate
Well, now that I’ve cracked using the WS2812B LEDs – I guess I’d better share the results – especially as it was the work of others that started me off on this road! I went down a LOT of dead routes with this – firstly I was going to have…
ESP8266 and MQTT Exciting Times
I don’t want to jump in prematurely here but those of you who have been reading the blog will know that I’ve had no end of problems with the MQTT stand-alone software on the ESP8266, but as each problem has emerged, the author (Minh Tuan) has been keeping in touch…
The ESP8266 Grand Master Plan
So… here’s where I’m up to with my little project… currently stalled until we can figure out why the ESP8266 is not recovering from loss of WIFI. This is “the plan. Using the basic MQTT code, I’ve added the ability to control GPIO0 and take input from say a Dallas…
