Hi, Great work! I'm a noobie and really appreicate your work. Having a little problem.

I'm trying to compile the 03-hx711-scale-esp-12.ino in the arduino ide 1.6.9. I'm getting the following error. I've added the folder structure in the arduino folder and i've added it to my libraries file but no luck. any other suggestions? I'm trying to run it on an esp 8266 12e. Thanks!

Error:

hx711scaleesp12k.ino:17:39: fatal error: /usr/local/src/ap_setting.h: No such file or directory

include "/usr/local/src/ap_setting.h"

chaeplin commented 8 years ago

do like this. ap_setting.h has some define.

//#include "/usr/local/src/ap_setting.h" // comment out this line
// add following and change values
#define WIFI_SSID "WIFI_SSID_CHAGE_THIS" 
#define WIFI_PASSWORD "WIFI_PASS_CHAGE_THIS"
#define MQTT_SERVER { 192, 168, 10, 10 } // server ip of mgtt
#define OTA_PASSWORD "OTA_PASSWORD_CHANGE_THIS" // OTA password

then it looks like this https://gist.github.com/chaeplin/931c7e5b4d6e993c93acae85cfd6e136

I use this one now, for battery powered. https://github.com/chaeplin/esp8266_and_arduino/tree/master/_54-atmega328p-nrf24-gy-521-hx711

Hi, Thank you for your quick response. I modified the file (appreciate the example) which addressed the ap_settings.h issue. Now I am getting a series of effort around the average.h library.

If it helps, i'm simply trying to use a piece of code to pull values from the load cell. That's all. I've tried numerous libraries/scripts but none of them seem to work on the esp826612e. I even saw on Reddit your contribution on someone's hx711 issue - that script did not work for me either. error is < ets Jan 8 2013,rst cause:2, boot mode:(3,6) >

Appreciate your help and any additional thoughts.

kozoke commented 8 years ago

Hi, Thanks. I had looked at this sketch before but had similar problems. But, I tried it again, configured ap_setting.h and deleted and redownloaded the pubsubclient. No luck. Here are the errors.

Any other suggestions? Is there a segment of this code that just deals with the hx711? I use HomieOTA for my mqtt/wifi connectivity so I really just need to figure out how to read from the HX711.

appreciate your help.

FYI I took your code - prior suggestion _03 and pulled out all of the wifi/mqtt stuff. Good news is that it is not doing the soft reset. Bad news, it is only giving me a raw value of 65535. I had the hardware (hx711 and load sensors working correctly with an arduino yesterday so they should be fine. Here is what was left of your code when I stripped it down. Anything in here look wrong? I'll try your suggestion above now. Thanks!

void loop() { inuse = digitalRead(nemoisOnPin); if ( inuse == HIGH ) { requestHx711(); } delay(500); }

String macToStr(const uint8_t* mac) { String result; for (int i = 0; i < 6; ++i) { result += String(mac[i], 16); if (i < 5) result += ':'; } return result; }

void requestHx711() { Wire.requestFrom(2, 2);

 int x;

 a = Wire.read();
 b = Wire.read();

 x = a;
 x = x << 8 | b;

Serial.print(x);

 String payload = "{\"NemoWeight\":";
 payload += x;
 payload += "}";

sendHx711(payload);

}

This sketch is not esp8266 + hx711. It's esp8266 + pro mini(+ hx711).

So Arduino should have i2c connection to esp8266.

Hi, Just tried your suggestion above: It's https://github.com/bogde/HX711 example with ESP.wdtDisable. That didn't work - took me back to the bootloader message: ets Jan 8 2013,rst cause:2, boot mode: (3,6)

Seems like your _03 older script works (at least it isn't showing the bootloader message). I just confirmed the hardware is working with an arduino script called "simple_scale" (forget where i got it). I tried putting the Simple_Scale script (below) on the esp, changing the pings to d4,d5 and I got a fatal exception messages spooling across the screen.

Well, we are getting closer! any other ideas? thanks

I'm not sure i'm following. I pulled your code as suggested: esp8266_and_arduino https://github.com/chaeplin/esp8266_and_arduino/_03-hx711-scale https://github.com/chaeplin/esp8266_and_arduino/tree/master/_03-hx711-scale /old_scale_version https://github.com/chaeplin/esp8266_and_arduino/tree/master/_03-hx711-scale/old_scale_version /_03-hx711-scale-v1-adaptor https://github.com/chaeplin/esp8266_and_arduino/tree/master/_03-hx711-scale/old_scale_version/_03-hx711-scale-v1-adaptor /_03-hx711-scale-esp-12 https://github.com/chaeplin/esp8266_and_arduino/tree/master/_03-hx711-scale/old_scale_version/_03-hx711-scale-v1-adaptor/_03-hx711-scale-esp-12 /_03-hx711-scale-esp-12.ino

I pulled out the wifi and mqtt stuff and it ran but with only one repeating value.

You mention arduino hsould have i2c which I believe is included wire.h library which is still in the remaining code I sent. Also, please note i'm using a esp8266 12e dev board if that matters.

Clearly i'm missing something here. Am I using the old or wrong wire.h library?

thx

Which esp do you use? How do you connect esp, arduino and hx711 ?

kozoke commented 8 years ago

Esp8266 12e amica

chaeplin commented 8 years ago

Esp8266 use 3.3V. Which arduino board do you use ?

If arduino board use 5V, you need i2c level shifter. http://playground.arduino.cc/Main/I2CBi-directionalLevelShifter

kozoke commented 8 years ago

Hi Arduino uno.

I have the esp powered through the usb 5v pin. I'll look at the guidance about level shifting. That is new to me

chaeplin commented 8 years ago

Uno i2c use 5V, esp i2c use 3.3V. So voltage level shifting is needed. https://www.youtube.com/watch?v=VDfI546YThQ

kozoke commented 8 years ago

Ok. Let me look into it and get back to you. Again, thanks for your patience and support.

chaeplin commented 8 years ago

Check this for i2c. http://gammon.com.au/i2c https://learn.sparkfun.com/tutorials/i2c

kozoke commented 8 years ago

Ok but... The hx711 takes 2.6 to 5v input. If I just change input voltage to the 3.3v pin instead of the 5v pin wouldn't that work? Or am I missing something?

chaeplin commented 8 years ago

@kozoke Which combination do you use ? Let me check again. 1) esp8266 + hx711 : some variation on hx711 reading 2) esp8266 --i2c--arduino-hx711 : reliable on hx711 reading

If it's 1) you don't need level shifting. 2) then you need level shifting between esp8266 and arduino, not hx711.

esp8266 + hx711

chaeplin commented 8 years ago

hmm 1) then you should check https://gist.github.com/chaeplin/d3cc3675982d8c92455b It should work. If not, change pins sck and dout. When I use more than 5 in scale.read_average(?) and scale.get_value(?) error occurred. After uploading sketch, reset once more for sure.

kozoke commented 8 years ago

Tried the sketch above. No luck. I'm back to the "ets Jan 8 2013,rst cause:2, boot mode: (3,6)" Same error if I use the 3.3v pin or the 5v pin.

I did not understand your statement. "If not, change pins sick and dout - you mean change the sda and clock pins? they are on d4 for data and d5 for clock. Those are the defaults I believe?

You also said, "When I use more than 5 in scale.read_average(?) and scale.get_value(?) error occurred." Do you mean, when you use 5v vs 3.3v you see the monitor? Don't understand the reference to scale.read_average and scale.get_value. Can you clarify?

I also tried re-downloading the bodge/hx711 library you refer to in your readme fiile. That didn't help and made your sketch above kick out error messages (see below).

I'm just baffled by this. Do you have the esp12 and hx711 or is your set up different?

chaeplin commented 8 years ago

1) HX711(byte dout, byte pd_sck, byte gain = 128); --> out to 4, sick to 5(4, 5 is not fixed, can use other pins) 2) esp vcc(3.3) to vcc of hx711, and esp gnd to gnd of hx711 3) looks like download err to me. How do you download hx711 library ?

kozoke commented 8 years ago

1) OK yes, understand that. I'll double check the pins. Assume 4 =D4 on my board and =D5 on my board (esp 8266 12e). That makes sense. 2) Yes - agree on 3.3 to vcc and ground to ground. all good there. 3) I went to the link and downloaded the zip from the site you refer to - https://github.com/bogde/HX711 I then go into board manager in the arduino IDE and import it. Then I go in and ensure the .h file is in the HX711 directory (not in a second sub directory).

I'm sure i'm missing something obvious... Just don't know what it is, yet.

I think i'm going to set up another pc with an arduino IDE and reinstall just your recommended ino and libarary (with nothing else) and give that a try.

I also posted another message on the www.8266.com site to see if anyone else has had any luck with this config - esp826612e - http://www.amazon.com/HiLetgo-Version-NodeMCU-Internet-Development/dp/B010O1G1ES?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01

Linked directly to: hx711 ( http://www.amazon.com/SMAKN%C2%AE-Weighing-Dual-channel-Conversion-Shieding/dp/B00M6POINC?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 )

chaeplin commented 8 years ago

download https://github.com/bogde/HX711 and unzip it. Find Arduino library folder, move unzipped lib to that folder.

kozoke commented 8 years ago

Solved. I went through and blew away all remants of anything hx711 in the libraries/scripts. Downloaded the Bogde and tried that. I also recall something about pin assignments so I added this to the code: (and changed the .ino pins to 4 for data, 5 for clock)

ifndef Pins_Arduino_h

define Pins_Arduino_h

include "../generic/common.h"

static const uint8_t SDA = 4; static const uint8_t SCL = 5;

static const uint8_t LED_BUILTIN = 16; static const uint8_t BUILTIN_LED = 16;

static const uint8_t D0 = 16; static const uint8_t D1 = 5; static const uint8_t D2 = 4; static const uint8_t D3 = 0; static const uint8_t D4 = 2; static const uint8_t D5 = 14; static const uint8_t D6 = 12; static const uint8_t D7 = 13; static const uint8_t D8 = 15; static const uint8_t D9 = 3; static const uint8_t D10 = 1;

endif /* Pins_Arduino_h */

And, it kinda worked but was getting a reading but also a stack error.

So, I tried this one (simple scale - which seemed to work before). https://github.com/queuetue/Q2-HX711-Arduino-Library And it worked! Responded well to changes in load sensor pressure!!! So, it was a library problem or more likely a pin assignment.

Thanks again for your help patience and support. I hope this helps someone else in the future.

chaeplin commented 8 years ago

@kozoke Oh great. Thanks for info on new lib.

broskunta commented 7 years ago

@kozoke Please can I see a sample code that worked. I am having issues setting up the ESP8266 to work with the HX711 library. Thanks.

kozoke commented 7 years ago

Hi, This is my code for a homie (wifi/mqtt) dog food bowl scale. It isn't very accurate but good enough to flag when my dog gets food and is done (weight rises and drops below a certain point).

That said, the code works. Does that help?
