ESP32 develop with Arduino IDE



ESP32 Develop with Arduino IDE
I've just ESP32 Development Board call Nano32 from Gravitech / MakerAsia.
The new ESP32 WiFi chip from ESPressis System improve over ESP8266 WiFi Module.
see the spec.
http://microcontrollerkits.blogspot.com/2016/10/esp32-development-board-form-gavitech.html

Now ( Oct10 ,2016 ) announced Arduino Core for ESP32 WiFi Chip

https://github.com/espressif/arduino-esp32

The following was the setup environment for ESP32 with Arduino IDE



STEP 1  
Download Arduino core for ESP32.



Then Unzip and we will copy all this file to Arduino IDE directory or path later.



STEP 2
If Install Arduino IDE already. Find the path of Arduino IDE Installation directory.

Example
My Computer in C:/Program Files (x86)/Arduino


Make New folder name espressif in the hardware directory


and make subfolder in espressif  folder name esp32



Then copy all files from download into this directory. ( esp32 )



or Use Command Line 
cd hardware
mkdir espressif
cd espressif
git clone https://github.com/espressif/arduino-esp32.git esp32


STEP 3
Use Python 2.7 Command 
if you don't have it. download Python 2.7 https://www.python.org/downloads/



Then Use Command Line
cd esp32/tools
python get.py

My Example




STEP 4 Open Arduino IDE
Now, You will have Board ESP32 Dev Module and Select port





STEP 5 Test Compile and Upload Example Code

Test Blink in Example Code



Done Uploading.
Upload code faster than ESP8266 very much.

Reference ( Fixed some bugs ) Thank you for that.

ESP8266 Eclipse Development



ESP8266 and Eclipse Development

Eclipse have use for many developer for Android Development, php or C/C++.
Now,Eclipse can use with ESP8266 WiFi Module development also.

If you are not use eclipse before then download first.

Prepare your Eclipse environment for C/C++ programming

1.Download Eclipse  https://eclipse.org/downloads/




2.Install Eclipse CDT ( C/C++ Development Tooling)

Open Eclipse




Goto Menu Help => Market Place 



Find CDT then Install





3.Install C Compiler ( MinGW )

Download and install MinGW. Get mingw-get-setup.exe from the official SourceForge project.







4.Install ESP8266 SDK

Download and install Mikhail Grigoriev’s Unofficial Development Kit for Espressif ESP8266.

( 141 MB )



5.Install MinGW script 
http://programs74.ru/get.php?file=EspressifESP8266DevKitAddon
Mikhail Grigoriev made some awesome scripts to automate the installation of additional modules in MinGW which are needed for compiling. You can download his package here, extract it somewhere and then run install-mingw-package.bat.




How to Open Example Code and Flash

When you have prepare your Eclipse Environment already.
Import Example code and Flash to ESP8266 WiFi Module.

See on VDO above.

Goto Menu File => Import



Then Select Existing Projects into Workspace



Select Espressif  Example folder




Test Blinky2 Source Code



Then Flash to ESP8266 WiFi Module

ESP32 WiFi and Bluetooth Module form Espressif ( NEW )



ESP32 WiFi and  Bluetooth LE Module form Espressif ( NEW )


So many of us have been happily using in the inexpensive ESP8266 chips for some time now for IOT applications, home control etc and long may that continue. They do have SOME issues – for example they are short of RAM memory to the point that all except critical subroutines have to be stored in FLASH and pulled out when needed. The somewhat slows things down as the 80Mhz processor (160Mhz at a pinch) has to pull stuff out of the external serial FLASH to use it. In practice the ESP8266 is still very fast but this is just one step that would be nice to avoid. Lack of IO lines also is a little painful as so many of the available lines are dual purpose – GPIO0 for example cannot be held low on powerup as it is used to put the processor into programming mode. We get around these issues but wouldn’t it be nice if we didn’t have to.

Espressif teased us about a successor to ESP8266 a few months ago that would support both WiFi and Bluetooth Low Energy, and John Lee, working for Espressif Systems, has now sent a letter to ESP8266 developers announcing the new wireless SoC with two Tensilica L108 cores and called ESP32.



Espressif ESP32 key improvements over ESP8266:

Faster WiFi – Wifi has been upgraded to support HT40 speed (144.4 Mbps) and has a new RF architecture to simplify the application schematics
Bluetooth Low Energy and Classic
Dual core processor – 2x Tensilica L108 processors clocked at up to 160 MHz
Low Power Mode Improvements – ADC conversions, level thresholds, etc.. can now be performed in deep sleep
Peripherals – Capacitive touch, ADCs, DACs, I2C. UART, SPI, SDIO, I2S, RMII, PMW, etc… but no USB.
More RAM – ~400 KB on-chip RAM
Security – Hardware accelerated AES and SSL, and more undisclosed improvements.
Simplified APIs – Not many details provided here, except WiFi APIs will be simplified, yet keep good flexibility and control.

One of my contact also informed me that there were two PGA (Programmable Gain Amplifier) blocks connected to two ADC blocks in the chip, which could be used for power metering with one PGA/ADC block used for voltage measurement, and one PGA/ADC block for current measurement. So ESP32 would offer a one chip solution for smart sockets. [Update: A few more information gathered from twitter: Close to 40 GPIOs, IPV4 and IPv6 support, beta@espressif.com is where you want to write to apply for a board, QFN package, not much more expensive than ESP8266, …]

The letter promises that beta testing will start soon with about 200 applications boards to be sent out, and a bounty program will be launched for people who can successfully compromise ESP32 security. The CEO also made a call to engineers who are interested in working with the company in Shanghai.


In case you’ve been hiding under a virtual rock over the last two years, you might have missed it when Espressif turned the IoT game on its head by releasing a chip with WiFi and a decent embedded processor for under $1 in bulk, and costing not much more than that in a module.


They’re looking to repeat the success of the ESP8266 with the ESP32, that should be coming out any time now. As we get closer to the release date, details start to dribble out. [Alberto], who makes very nice-looking pinout diagrams for a number of our favorite chips and modules, has already made us an ESP32 module pinout diagram.





And [Rudi] has been digging up nearly every crumb of info on the ESP32 that’s publicly available. For instance, it was through his website that we learned that the new RTOS SDK source is already up on GitHub.
https://github.com/espressif/ESP32_RTOS_SDK

There’s also a source of official information in the ESP32 forum, but there’s not much news there just yet. We expect this to change as more beta units make it out into the wild.

We covered the announcement of the forthcoming ESP32 last month, and we have to say that we’re looking forward to getting a module or two in our hands. Twin cores, BTLE support, and better DMA are tops on our list of neat features.
