# ESP8266_swiss_army_board
|
|
|
|
Arduino based project running on my custom made board
|
|
|
|
## The hardware :
|
|
|
|
**The board :**
|
|
|
|
|
|
|
|
**The modules :**
|
|
|
|
|
|
### Hardware pin mapping :
|
|
|
|
(This image wasn't done by me)
|
|
|
|
**So we have :**
|
|
* I2C (for OLED screen and RTC)
|
|
* GPIO4 --> SDA
|
|
* GPIO5 --> SCL
|
|
* SPI (for µSDCard)
|
|
* GPIO13 --> MOSI
|
|
* GPIO12 --> MISO
|
|
* GPIO14 --> CLK
|
|
* GPIO2 --> µSDCard CHIP_SELECT
|
|
* FLASH_BTN
|
|
* GPIO 0
|
|
|
|
## Here is a list of the components needed in order to build such a board :
|
|
* 1x 1N4001 reverse voltage protection diode
|
|
* 1x AMS1117 5v voltage regulator
|
|
* 1x AMS1117 3.3v voltage regulator
|
|
* 2x 22µf electrolytic capacitors
|
|
* 2x 0.1µf (code 104) tantalum capacitors
|
|
* 1x jumper
|
|
* 1x 2 pins male header
|
|
* 1x On/Off switch
|
|
* 2x push buttons
|
|
* 1x ESP8266 E12
|
|
* 1x 19 pins female header
|
|
* 1x 2 screws terminal
|
|
* 1x micro USB socket
|
|
* 1x 100 ohm resistor
|
|
* 2x 1k ohm resistor
|
|
* 1x 6.8k ohm resistor
|
|
* 1x 3.9k ohm resistor
|
|
* 1x 22k ohm resistor
|
|
* 2x 10k ohm resistor
|
|
* 1x 33k ohm resistor
|
|
* 1x 4.7k ohm resistor
|
|
* 1x 7cmx5cm pcb
|
|
|
|
## The software :
|
|
### Default FLASH Options (for the Arduino IDE) :
|
|
|
|
|
|
### I2C Hardware addresses :
|
|
* OLED screen : 0x3C
|
|
* RTC DS3231 : 0x68
|
|
* PCF8574 : 0x27
|
|
|
|
### External librairies used :
|
|
* Adafruit_SSD1306 (not my work) [link](https://github.com/adafruit/Adafruit_SSD1306)
|
|
* Adafruit-GFX (not my work) [link](https://github.com/adafruit/Adafruit-GFX-Library)
|
|
* RTClib-master (not my work) [link](https://github.com/adafruit/RTClib)
|
|
* AT24CXX-master (not my work) [link](https://github.com/cyberp/AT24Cx)
|
|
|
|
/!\ Some of these librairies have been modified for the project, thus, it is recommended to get them from the repository here : [link](http://82.64.196.164/git/Th3maz1ng/ESP8266_swiss_army_board/src/branch/master/src/libs)
|
|
|
|
### SD Card structure (subject to changes) :
|
|
``` json
|
|
/
|
|
|_CONFIG
|
|
| AP.CFG
|
|
| SCREEN.CFG
|
|
| SERVER.CFG
|
|
| STA.CFG
|
|
|_FTP
|
|
|_LOGS
|
|
|_WWW
|
|
```
|
|
### Example of a config file structure (.CFG) :
|
|
``` json
|
|
#This line is a comment and will be ignored
|
|
#All comments should be at the top of the file
|
|
#The parameter names are case sensitive /!\
|
|
|
|
this_is_the_parameter_name : this_is_a_numeric_value
|
|
'this is the parameter name' : this_is_a_numeric_value
|
|
this_is_the_parameter_name : 'this is a string value'
|
|
'this is the parameter name' : 'this_is_a_string_value'
|
|
|
|
```
|
|
### For AP.CFG it would be :
|
|
``` json
|
|
#This config file stores the configuration needed to set the AP
|
|
#up for the ESP8266SwissArmyBoad
|
|
#If this file is not present or if there is an error at parsing time
|
|
#default values will be used instead.
|
|
#If the password is an empty string aka '', the network will be open
|
|
|
|
SSID : 'ESP8266SwissArmyBoard'
|
|
PASSWORD : 'APassWord'
|
|
CHANNEL : 1
|
|
SSID_HIDDEN : 'true'
|
|
AP_MAX_CONNECTION : 4
|
|
|
|
```
|
|
### For STA.CFG it would be :
|
|
``` json
|
|
#This config file stores the configuration needed to connect the board
|
|
#to a wifi hotspot
|
|
#If this file is not present or if there is an error at parsing time
|
|
#only the AP functionality will be enabled
|
|
|
|
SSID : 'MyHotspotSSID'
|
|
PASSWORD : 'MySuperSecuredPassword'
|
|
|
|
```
|
|
|
|
