[feedback] Keeping the website updated...

Espressif... you might want to consider better arranging the blog regarding latest updates of the SDK.. Some of us check in frequently to see if there are any updates for example: http://bbs.espressif.com/viewtopic.php?f=46&t=2198 If you look on the right side - there is a box detailing the very...

Re: PWM FAILURE

This has now been solved. see http://tech.scargill.net/pwm-woes/ It would appear that the manual definition of pwm_init IS wrong - and also there is a potential alignment problem in the SDK - see comments here. http://www.esp8266.com/viewtopic.php?f=6&t=4675&p=46060#p46060 Espressif need to ...

PWM FAILURE

I am using the latest SDK - programming the ESP8266 (ESP12) in C. I have had PWM running for some time but not tested it for a few months. Now that I come to test, it is crashing. I thought I'd look at the SDK manual (1.5.2) and I noted that the manual states... for PWM_INIT - that the duty is a uin...

Re: ESP8266 RAM Size

Espressif - any chance of a reply to this one - I cannot use the latest SDK as my .TEXT memory is at 7ace on the previous SDK and runs out with the new one - anything I can strip out or change in the SDK? I've already put all my routines in FLASH

Re: ESP8266 RAM Size

It would appear that as of SDK 1.5.2, Espressif are using more .TEXT Ram - my code which compiles perfectly under 1.5.1 and previous will no longer compile complaining that it is out of .TEXT space. What can be done to reduce this - I already have my functions using the DIRECTIVE to keep functions i...

ESP8266 Registers and other Information

Hi I'm working on a project to uniquely identify an ESP8266 using statistics over time. Hence I need as much out of the ESP as possible that varies from device to device, location to location, power supply to power supply etc.. Useful starters are RSSI, ADC (noise), RTC calibration and of course fix...

Automatic router selection

I wonder if anyone who has done this can help. I program my ESP8266 devices in C. I've been having some issues with weak signal recently and it would be really nice to have a list of acceptable access points and their passwords - and have the ESP, if it loses the signal, check the list (including id...

Interference

I'm wondering how many of you have experience of having several ESPs working in a small environment - perhaps 8 or 9 units or more in a couple of rooms. I've had some horrendous router problems recently and at first I was blaming the router - now I'm not so sure? I'm wondering about purity of signal...

Get the IP address

I can see how to set a fixed IP in the ESP (SDK 1.4) and how to read the RSSI - all of which is great. But can someone show me a C example of retrieving the current IP address. There's info in the SDK manual for a function which returns a struct with info - but unless I'm missing something there is ...
