Apps that use jerry should not (must not!) include and rely on its
internal headers. Typical issue is the use of "jrt/jrt.h". Fixing
`main-{unix,mcu}.c`, and speculatively the apps under the `targets`
directory as well.
(Note: a fix can be either including "jerry-port.h" and using
functions declared there, e.g., `jerry_port_errormsg`, or simply
using standard libc function like `printf`. Both approaches occur
in this patch.)

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 page.
How to build JerryScript for ESP8266
1. SDK
Follow this page to setup build environment
2. Patch ESP-SDK for JerryScript
Follow this page to patch for JerryScript building. Below is a summary after SDK patch is applied.
3. Building JerryScript
cd ~/harmony/jerryscript
make -f ./targets/esp8266/Makefile.esp8266 clean
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.
- Power off ESP8266
- Connect GPIO0 to GND and GPIO2 to VCC
- Power on ESP8266
- 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
- Power off
- Disonnect(float) both GPIO0 and GPIO2
- 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.
