1. Add libssc.a, simple serial console lib. 2. Add libspiffs.a, SPI file system. 3. Add libwps.a to support WPS. 4. Add libespconn.a, Espressif connection lib. 5. Add libespnow.a to support Espressif ESP-NOW. 6. Add libmesh.a, Espressif mesh. 7. Add libnopoll.a, websocket. 8. Add make_lib.sh in "third_party" folder. 9. Add modem-sleep & light-sleep supported. 10. Update libcirom.a to support float IO. 11. Update gen_misc.sh & gen_misc.bat. 12. Update header files, add comments in doxygen style. 13. Update libsmartconfig.a to version 2.5.2. 14. Update libssl.a. 15. Updates driver (PWM/UART/GPIO/SPI/Hardware timer). 16. Update open source codes of third_party. 17. Modify "ld" files, "dram0 len" should be 0x18000 in RTOS SDK. 18. Remove header files in extra_include, which are already in compile folder. 19. Other APIs sync from non-OS SDK, more details in documentation "20B-ESP8266__RTOS_SDK_API Reference". 20. Other optimization to make the SDK more stable.
This is a simple project template.
sample_lib is an example for multi-level folder Makefile, notice the folder structure and each Makefile, you can get the clue.
HOWTO:
1. Copy this folder to anywhere.
Example:
Copy to ~/workspace/project_template
You can rename this folder as you like.
2. Export SDK_PATH and BIN_PATH.
Example:
Your SDK path is ~/esp_iot_rtos_sdk, and want generate bin at ~/esp8266_bin.
Do follow steps:
1>. export SDK_PATH=~/esp_iot_rtos_sdk
2>. export BIN_PATH=~/esp8266_bin
SDK and project are seperate, you can update SDK without change your project.
3. Enter project_template folder, run ./gen_misc.sh, and follow the tips and steps.
Compile Options:
(1) COMPILE
Possible value: xcc
Default value:
If not set, use gcc by default.
(2) BOOT
Possible value: none/old/new
none: no need boot
old: use boot_v1.1
new: use boot_v1.2
Default value: new
(3) APP
Possible value: 0/1/2
0: original mode, generate eagle.app.v6.flash.bin and eagle.app.v6.irom0text.bin
1: generate user1
2: generate user2
Default value: 0
(3) SPI_SPEED
Possible value: 20/26.7/40/80
Default value: 40
(4) SPI_MODE
Possible value: QIO/QOUT/DIO/DOUT
Default value: QIO
(4) SPI_SIZE_MAP
Possible value: 0/2/3/4/5/6
Default value: 0
For example:
make COMPILE=gcc BOOT=new APP=1 SPI_SPEED=40 SPI_MODE=QIO SPI_SIZE_MAP=0
