On the lookout for a maths type.. I’m about to do a blog item on PWM on the ESP8266 – the reason for that is – they’ve some new code which currently isn’t 100% or I’d be writing it up now – but suffice it to say the maximum duty…

Espressif 1.10 SDK Experience
Update 04/June/2015 I must say I cannot really gripe about support from Espressif……. I received an email this morning to ask me to use another FLASH tool – that failed – same result – code compiled under the old 1.01 SDK worked – code compiled under 1.10 SDK failed. Eventually,…
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
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…
Deployment Beckons
I’m now getting dangerously near the point where I have to DO something with all of this ESP8266 control stuff. We’re at our Spanish cave and I’ve a watering system to sort – a simple example – so one of the ESP12 boards has a relay on it and another…
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..…
Lots of Users
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…
Web Sockets Web Page Part 3
For this to make sense you should look at Websockets Web Page Part 1 and Websockets Web Page Part 2 first. In this final section I add styling to the page and also change the code so that you can send a partial message i.e. {“my_input”:”Hello”} without affecting other parts…
ESP8266 SDK v1.0.0 Out Now
The new esp8266 SDK v1.0.0 is out now including various optimisations and a half-decent English manual. How far we have come since only a few short months ago when the code was full of bugs and the English documentation almost non-existent. Today you can get paid to report bugs!! According…
LED Quick Test
Quick test of the new ESP8266 code for driving the ws2812b LEDs… not far off 2 amps at 5v in at one end – GND and ESP8266 signal other end… fully tested with 300 serial LEDS – this is my next WIFI SAD LIGHT once I find something with enough…
Domain Issues on Pi 2
So a little while ago, one of you helpful people in here gave me a tip when my Raspberry Pi 2 based CRON JOB started up and failed to send emails. I added MAILTO: pete@scargill.org to whatever I was working on and lo and behold the emails worked. But now…
Thanks
Just a quick note to those of you who come in here, are constructive and offer help and hopefully sometimes take away information… thanks for taking the time – and thanks for putting up with the name change of the blog – which got me away from reliance on WordPress.com. …
Rubbish plug-ins
Another rubbish spam plug-in – apologies to anyone who’s been trying to comment this morning – I really do not understand some of the people that give stars to WordPress plug-ins. I used an anti-spam system that got high ratings – and it would not let people comment – when…
Slight hitch
Apologies to anyone looking in this morning. I tried to get just a little too clever with the blog and it fell over – so anyone looking in while I was asleep (British time) would have seen a dead site – all working. As this blog is new could you…
The Mighty 1284p
The 1284p is the next step up from the ATMega328 chip powering many of the “Arduino” type microcontroller boards and their many clones. Why another chip? Well, anyone who has used the ATMega328 knows that it’s a great controller chip but the lack of RAM soon gets very tiring. Also…
