### About
|
|
|
|
Files in this folder (embedding/esp8266) are copied from
|
|
`examples/project_template` of `esp_iot_rtos_sdk` and modified for JerryScript.
|
|
You can view online from
|
|
[this](https://github.com/espressif/esp_iot_rtos_sdk/tree/master/examples/project_template) page.

### How to build JerryScript for ESP8266
|
|
|
|
#### 1. SDK
|
|
|
|
Follow [this](./docs/ESP-PREREQUISITES.md) page to setup build environment
|
|
|
|
|
|
#### 2. Patch ESP-SDK for JerryScript
|
|
|
|
Follow [this](./docs/ESP-PATCHFORJERRYSCRIPT.md) page to patch for JerryScript building.
|
|
Below is a summary after SDK patch is applied.
|
|
|
|
#### 3. Building JerryScript
|
|
|
|
```
|
|
cd ~/harmony/jerryscript
|
|
# clean build
|
|
make -f ./targets/esp8266/Makefile.esp8266 clean
|
|
# or just normal build
|
|
make -f ./targets/esp8266/Makefile.esp8266
|
|
```
|
|
|
|
Output files should be placed at $BIN_PATH
|
|
|
|
#### 4. Flashing for ESP8266 ESP-01 board (WiFi Module)
|
|
|
|
Steps are for `ESP8266 ESP-01(WiFi)` board. Others may vary.
|
|
Refer http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family page.
|
|
|
|
##### 4.1 GPIO0 and GPIO2
|
|
|
|
Before flashing you need to follow the steps.
|
|
|
|
1. Power off ESP8266
|
|
2. Connect GPIO0 to GND and GPIO2 to VCC
|
|
3. Power on ESP8266
|
|
4. Flash
|
|
|
|
##### 4.2 Flashing
|
|
|
|
```
|
|
make -f ./targets/esp8266/Makefile.esp8266 flash
|
|
```
|
|
|
|
Default USB device is `/dev/ttyUSB0`. If you have different one, give with `USBDEVICE`, like;
|
|
|
|
```
|
|
USBDEVICE=/dev/ttyUSB1 make -f ./targets/esp8266/Makefile.esp8266 flash
|
|
```
|
|
|
|
|
|
### 5. Running
|
|
|
|
1. Power off
|
|
2. Disonnect(float) both GPIO0 and GPIO2
|
|
3. Power on
|
|
|
|
Sample program here works with LED and a SW with below connection.
|
|
* Connect GPIO2 to a LED > 4K resistor > GND
|
|
* Connect GPIO0 between VCC > 4K resistor and GND
|
|
|
|
If GPIO0 is High then LED is turned on longer. If L vice versa.
