ESP8266 SDK 1.10 Different

May 31, 2015 Peter ScargillUncategorized6 Comments on ESP8266 SDK 1.10 Different

Something odd here.   So I’ve downloaded the latest ESP8266 SDK version 1.10 and while one of my bigger projects is ok, another fails miserably. If you look at some of the items below… PIN_PULLDWN_DIS for example – that is most definitely in EAGLE_SOC.H in the previous version – yet…

Apologies

May 28, 2015 Peter ScargillUncategorized3 Comments on Apologies

Apologies to anyone who tried to register yesterday or this morning. In an attempt to reduce false registration I added a plug in to include captcha – well that worked a treat except in the process it altered the responses to new uses so that they didn’t get a password…

Raspberry Pi 2 Logging

May 27, 2015May 27, 2015 Peter ScargillRaspberry Pi 212 Comments on Raspberry Pi 2 Logging

Here’s a thing… if you’re using a Raspberry Pi as some kind of central controller for long-term home control or other data logging application you will no doubt be aware of the potential issues with FLASH memory. The Pi will let you use Linux and log stuff and shove information…

ESP8266 FLASH– Something to Ponder

May 27, 2015May 27, 2015 Peter ScargillESP826613 Comments on ESP8266 FLASH– Something to Ponder

Update: You’ll see from the original article before the break, I was having serious problems with ESP-01 versus ESP-12 etc where code running in the 12 would simply not work on the ESP-01. Well, it turns out none of this was helped by the MAKEFILE.. You’ll often see references to…

ESP8266 Progress

May 21, 2015May 21, 2015 Peter ScargillDS18B20, ESP-12, ESP12, ESP8266, MOSFET, Node Red, Raspberry Pi 212 Comments on ESP8266 Progress

There can be no doubt that I still have some way to go in terms of reliability with my test rig in Spain before putting this stuff in charge of the heating back home in the UK: Raspberry Pi 2 is on an un-interruptible supply but does not 100% recover…

Moisture Sensing Conundrums

May 19, 2015May 19, 2015 Peter ScargillESP8266, moisture sensing52 Comments on Moisture Sensing Conundrums

I’ve been playing (as you’ll know if you’ve read previous blogs here) with moisture sensing. It’s easy really to do this – you just put a low voltage through a couple of bits of metal and sense the current going through. All things being equal, the more current, the wetter…

Deployment Beckons

May 16, 2015May 16, 2015 Peter ScargillUncategorized

I’m now getting dangerously near the point where I have to DO something with all of this ESP8266 control stuff. We’re at the cave and I’ve a watering system to sort – a simple example – so one of the ESP012 boards has a relay on it and another has…

ESP-12E with Extra Pins!

May 12, 2015December 19, 2018 Peter ScargillESP-12, ESP-12E, ESP826651 Comments on ESP-12E with Extra Pins!

Here’s the picture. £2.25 including post – what more could you want! So this is like an ESP-12 – already the best of the bunch – but with more IO – specifically 6 more IO lines… this just keeps on getting better – whatever next, built in Bluetooth?? Well that’s…

Raspberry Pi I2C and the Real Time Clock

May 10, 2015May 10, 2015 Peter ScargillRaspberry Pi 2

I’ve been wondering how to detect an I2c device attached to pins SDA0 and SCL0 on the Pi – now I know – easy.. https://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi/wiring-the-rtc

The Worlds first $9 Computer

May 9, 2015December 19, 2018 Peter ScargillUncategorized7 Comments on The Worlds first $9 Computer

Oh yes, I like this.. By the look of it not available until next year – a tiny board with the power perhaps of something like a Raspberry Pi but tiny and lower cost (well, that’s IF the postage doesn’t kill it).  I’ll be keeping an eye on this one..…

DIL Adaptor for ESP07 and ESP12

May 9, 2015May 9, 2015 Peter ScargillESP-07

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

May 9, 2015May 9, 2015 Peter ScargillESP-01, ESP-07, ESP-12, ESP12, ESP826627 Comments on 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…

Using Skype

May 9, 2015 Peter Scargillskype2 Comments on Using Skype

For those used to seeing me rant about micro-controllers this may seem a little odd, but I thought I’d drop this in here as a diversion to give others the benefit of my experience as IT Chairman of a fairly large national organisation. About 14 years ago the organisation decided…

Using GroveStreams

May 7, 2015 Peter ScargillGroveStreams9 Comments on Using GroveStreams

No sooner did I finish the blog on my new GroveStreams Node than I was faced with the question “how do I use GroveStreams?” Well, that’s generally up to you – but I will start you off on how I use GroveStreams – and the ridiculously simple setup (once you…

A GroveStreams Node Red Node

May 6, 2015December 1, 2015 Peter ScargillArduino, ESP-01, ESP-12, ESP8266, GroveStreams, Node, Node Red, Raspberry Pi 212 Comments on A GroveStreams Node Red Node

One of the more obvious things to do with a home control system is to capture information like temperature and humidity – and to graph it.  For example I spent part of my time in the UK and part of it in Spain. When I’m not in Spain it is…

To GIT – or Not to GIT

May 5, 2015May 6, 2015 Peter ScargillGit9 Comments on To GIT – or Not to GIT

For years I’ve been using DropBox on my various Windows PCs to make shared file access easy… and at work, my PA and I have shared DropBox folders for just as long. And that’s fine for lots of things, it certainly makes access when on location easy, but it is…

I was just looking at the stats for the blog and in the short time this new version has been up and running I’ve something like 1300 subscribers – which is nice – but only a small percentage talk to us! So – obviously you’re here because you are into…
