make issue #7

Closed kim-rok closed 6 years ago

kim-rok commented 6 years ago

With the problem "wdt reset", I try remake the firmware. Before "make" command, I changed the value of the "build area" in the Makefile, and wifi AP mode variable( ssid, and password) in "user_config.h" in user directory. After correction, I applied "make" command at "user" directory but I got error....

kim@kim-R510-P510:~/opt/esp_mqtt/user$ make LD build/app.out /home/kim/opt/esp-open-sdk/sdk/lib/libmain.a(app_main.o): In function flash_data_check': (.irom0.text+0x770): undefined reference touser_init' /home/kim/opt/esp-open-sdk/sdk/lib/libmain.a(app_main.o): In function flash_data_check': (.irom0.text+0xb27): undefined reference touser_init' collect2: error: ld returned 1 exit status ../Makefile:122: recipe for target 'build/app.out' failed make: *** [build/app.out] Error 1

How can I solved the problem?

martin-ger commented 6 years ago

Try the "make" in the top directory.

kim-rok commented 6 years ago

Ok well made firmware.

But "wdt reset" continue with big capacitor. May be need Watchdog time off?

martin-ger commented 6 years ago

No, should work fine with watchdog. At least it does for me. Please try to disable "SCRIPTED" in user_config.h by commenting it out. Does this change anything?

martin-ger commented 6 years ago

Another idea what might be wrong: perpaps the flash read of the cript fails, beause there is something in the memory from previous firmwares. Clould you try to erease flash memory at 0xd000 by e.g. flash this empty bin there: https://github.com/CHERTS/esp8266-devkit/blob/master/Espressif/ESP8266_SDK/bin/blank.bin

Will also try to fix this, when I am back tomorrow.

1) 1MB ESP8266 + firmware with script function + blank.bin flashing, working AP, but mqtt client connection not maintained. 2) 4MB ESP8266 + firmware with script function + blank.bin flashing, serial consol connected with 74800(not 115200) and persistent reset(reset code 2) during boot.

kim-rok commented 6 years ago

solved problem the cause is unknown problem of esptool and blank.bin file size. Now sripting running well. But Mqtt client connection problem happened.

martin-ger commented 6 years ago

What kind of connection problem?

kim-rok commented 6 years ago

I figure out the connection problem. Thank for your support. Next I will drill the scripting.

My furnace project need PWM, ADC, DHT sensor reading and the result publish to client. The client number in my project is only 3. Is it possible to add DHT, ADC modules? If it is possible, can you explain the method?

martin-ger commented 6 years ago

PWM is already included, ADC could and should be included soon, but the DHT sensor is hard to add to a basic scripting language as it uses a specific serial bus protocol. Thus, probably the easiest way would be to use the Arduino environment with the DHT library, write a (simple) Arduino program and use esp_uMQTT_broker as an additional library (sample see at: https://github.com/martin-ger/esp_mqtt/blob/master/Arduino/uMQTTBrokerSample.ino )

martin-ger commented 6 years ago

ADC support has been added. ;-)
