Esp8266/Arduino. Everything ESP8266 - generic.upload.resetmethod: ck<->nodemcu. - Fri Nov 06, 2015 9:06 pm#33320 Using a NodeMCU there is some problem making downloads using the "Generic ESP8266 MODULE" in the boards manager.

Everything ESP8266 - generic.upload.resetmethod: ck<->nodemcu

Normaly I would choose the right board (NodeMCU 1.0), but actually testing with OTA, I am forced to take the generic-Board, because of its options "serial<->OTA"In older packages, I modified the boards.txt. I created a second Generic ESP8266-Module with the change from "generic.upload.resetmethod=ck" to "generic.upload.resetmethod=nodemcu"But always on changing to a new release, this options get lost.

And if I forget to change again, I am struggling on download This time, I was going a different way: I made the resetmethode switchable.

How to reduce program size. Memories of an Arduino. SRAM is the most precious memory commodity on the Arduino.

Memories of an Arduino

Although SRAM shortages are probably the most common memory problems on the Arduino. They are also the hardest to diagnose. If your program is failing in an otherwise inexplicable fashion, the chances are good you have crashed the stack due to a SRAM shortage. There are a number of things that you can do to reduce SRAM usage. These are just a few guidelines to get you started: If you are not sure whether a variable is being used or not, comment it out.

(Park the char* in Harvard PROGMEM) Literal strings are repeat memory offenders. Paul Stoffregen of PJRC and Teensyduino fame developed the F() macro as a super-simple solution to this problem. For example, replacing this: Serial.println("Sram sram sram sram. Serial.println("Sram sram sram sram.

Arduino with NodeMCU ESP8266 : How to use OTA with Arduino NodeMCU ESP8266. สวัสดีครับทุกคน กลับมาพบกันอีกครั้งนะครับ (^_^) ในครั้งนี้ผมจะมาพูดเกี่ยวกับเรื่อง Over The Air(OTA) ครับ หลายๆคนอาจจะเคยได้ยินมาบ้าง หรือไม่ก็อาจจะได้ยินกันเป็นครั้งแรกใช่ไหมละครับ เอาละมาเข้าเรื่องกัน OTA ก็คือการ update ตัว firmware แบบไร้สายนั้นเองครับ จะพบมากในอุปกรณ์ไร้สาย (wireless) ต่างๆ เช่น mobile phones , tablets , bluetooth devices เป็นต้นครับ และในบทความนี้ผมจะพูดถึงการใช้ OTA กับ Node ESP8266 บน Arduino ได้อย่างไรกันครับ เรามาเริ่มกันเลยครับ Go go go!

ESP8266 - On Websockets, mdns, OTA and LEDS

I haven't used the ESP8266 for the last six months, and was happy to go back using it, discovering many new libraries which were developed during this time. The last few months I've done a lot! Got married, went for a honeymoon for a month and moved to a new house. The last two weeks I could finally relax and go back to my hobbies.

I was doing a lot of houseworks since I moved to the new house, so I decided to combine business with pleasure and created a cool atmosphere lights for my living-room. Here's a video of how it looks like: The project is more than just leds - It is an robust IOT device sitting in my living-room, listening to different requests. In this post I will describe the assembly of this project, but also a lot about the code and problems I encountered on the way. tl;dr for the ADHD readers: Hope you got this far reading the post, here's my code, go and have fun!
