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. 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. (hope I understood the menu-structure correct) Code: Select allmenu.UploadSpeed=Upload Speedmenu.CpuFrequency=CPU Frequencymenu.FlashSize=Flash Sizemenu.FlashMode=Flash Modemenu.FlashFreq=Flash Frequencymenu.UploadTool=Upload Usingmenu.Resetmethod=Reset Methode <-------------------- adding this line.

Everything ESP8266 - What is the difference between QIO and DIO flash mode? OnlineHumidifier/9-Maintain at master · krzychb/OnlineHumidifier. How to reduce program size. Optimizing SRAM | Memories of an Arduino. SRAM is the most precious memory commodity on the 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. 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. With this: Serial.println(F("Sram sram sram sram. Serial.println(F("Sram sram sram sram. Will save you 180 bytes of wonderful SRAM! The Arduino string library allows you to reserve buffer space for a string with the reserve() function. ....

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! 1. เริ่มแรกเรามาเตรียมความพร้อมกันก่อนนะครับ ว่า Arduino ของเรา พร้อมที่จะเชื่อมต่อในเบื้องต้นกับ NodeMCU ไหมโดยไปที่ Tool -> Board -> Generic ESP8266 Module ต้องขึ้นอย่างในภาพนะครับ ถ้ามีแล้วไปขั้นตอนต่อไปได้เลย แต่ถ้ายังไม่มีละก็ให้เข้ามาอ่านในนี้ก่อนครับ Installing with Boards Manager 2.

ทำการเช็ค Version firmware ของ NodeMCU ครับ ให้ทำการลง firmware version 1.6.5-947-g339819f0 ก่อนนะครับ! 3. 4. 5. 6. 7. 8. ปล. If you have any question? How to use OTA with Arduino NodeMCU ESP8266.

OTA may be done using: Security Safety. Everything ESP8266 - ARDUINO IDE OTA EXAMPLE. - Thu Nov 05, 2015 4:09 pm#33181 The OTA implementation for esp8266 / Arduino by igrr is freaking awesome! I used the following s/w and h/w: • Arduino IDE 1.6.5• Platform package: esp8266-1.6.5-947-g39819f0• Sktech: DNS_SD_Arduino_OTA.ino • ESP module: LoLin NodeMcu V3 with CH340G It worked for me from the first attempt in the following simple seven steps: 1. Follow installation of Arduino IDE and ESP8266 board support described under 2. Upload python 2.7.10 (not 3.5.0, etc.), start installer, select “Add python.exe to Path” (not selected by default) and run installation. 3. Esp8266-ota-1.png 4.

The holiday season is near and that means another project with lots of leds :D (Check Last year E-Hanukkiah. 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. An ESP8266 which controls a 7 meters, 5050 RGB 12V led strip, 60Leds/meter.The ESP8266 is connected to the house router via WiFi.The ESP8266 receives data through a websocket on port 81, which means it can be controlled from any browser/OS.It supports mdns, so no need for IP address to communicate with the ESP8266 (Partially at the moment).It supports OTA (Over-The-Air) updates - So no need to connect it to the computer to update the code.
