So – I’ve learned quiet a lot in the past few days.. Watchdogs on the ESP8266 Since Espressif SDK 1.01 or thereabouts, watchdog timer operation seems to have changed – delays of any length even in init()  are out – or so it would seem? So I got onto Stanza…

As often as not, when I reset an ESP8266 by using the system reset call in the SDK, after flashing – for example. if (strcmp(token, “id”) == 0) {                    if (isQuery) RESPONSE(“ID=%s\r\n”, sysCfg.base);                    else if (strlen(strValue)>=2){                        strcpy(sysCfg.base, strValue);                        CFG_Save();                        system_restart();                    } The unit does not come out of reset.. the…

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…

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….…

(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…

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…

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 –…
