Downloading the Virtual Machine
Download ESP8266_lubuntu_20141021.ova
from: http://downloads.espressif.com/FB/ESP8266_GCC.zip
解開 ESP8266_GCC_LUBUNTU.ZIP 且參考ESP8266_GCC_LUBUNTU.docx
內有安裝步驟及程序
Download the ESP8266 RTOS SDK
Download ESP8266_RTOS_SDK_V1.5.0.7z from
http://domoticx.com/esp8266-wifi-software-software-development-kit-espressif/
Extract the RTOS SDK (參考http://iot-bits.com/articles/building-examples-in-esp8266-rtos-sdk/)
Compile an example project
- cd /home/esp8266/Share/ESP8266_RTOS_SDK_V1.5.0/example/project_template
- vi gen_misc.sh
- 編輯SDK_PATH=/home/esp8266/Share/ESP8266_RTOS_SDK_V1.5.0
- 編輯BIN_PATH=/home/esp8266/Share/ESP8266_RTOS_SDK_V1.5.0/BIN_dir
- chmod +x gen_misc.sh & ./gen_misc.sh
- 執行完後 BIN_dir 包含 BIN files
Flashing to ESP8266 chip TEST
#--------------------
補充說明:
BIN generation parameters
- STEP 1: use boot_v1.2+ by default
boot mode: new
This boot file is forced by default in the RTOS SDK. Users cannot opt for another version of boot.bin
- STEP 2: choose bin generate(0=eagle.flash.bin+eagle.irom0text.bin, 1=user1.bin, 2=user2.bin)
enter (0/1/2, default 0):
Choose option 0 if your firmware does not use FOTA feature (updates over Wi-Fi). Use options 1/2 for firmware with FOTA enabled.
- STEP 3: choose spi speed(0=20MHz, 1=26.7MHz, 2=40MHz, 3=80MHz)
enter (0/1/2/3, default 2):
Use the appropriate SPI flash chip access speed that suits your flash memory. It is recommended to use 40MHz or lower for best compatibility.
- STEP 4: choose spi mode(0=QIO, 1=QOUT, 2=DIO, 3=DOUT)
enter (0/1/2/3, default 0):
Type of flash chip and how it is connected to the ESP8266. This would be QIO for standard modules like the ESP-01 or ESP-12 series.
- STEP 5: choose spi size and map
0= 512KB( 256KB+ 256KB)
2=1024KB( 512KB+ 512KB)
3=2048KB( 512KB+ 512KB)
4=4096KB( 512KB+ 512KB)
5=2048KB(1024KB+1024KB)
6=4096KB(1024KB+1024KB)
enter (0/2/3/4/5/6, default 0):
This is relevant only for FOTA firmware that uses user1.bin and user2.bin.
As an example, a set of working configurations for the ESP-12E or ESP-12F module would be as follows for non-FOTA applications:
Step 1: new
Step 2: option 0
Step 3: option 2
Step 4: option 0
Step 5: option 4
#---------------------------------------------
project_template File structure
The template creates four files/directories:
user/main.cmain source file with program entry point. Start writing your code hereuser/user_config.huser defined configuration header, empty by default. SDK header files rely on the existence of this file, so don't delete it even if you don't use itdriver/empty directory to place code for drivers. Mainly to separate external components' driver code from the main code, can be deleted if not used.Makefileputting it all neatly together. Again, this was copied from an example project and I don't take credit for it.
