| 26 feb 2016 13:47:47 | New wattmeter project | Amirhossein | Hi Freddy ... hope to success this project ♥ after finishing this, please publish the Proteus format of this project with codes... ThankQ |
| 26 feb 2016 13:29:44 | Arduino wattmeter | Allan Lind | I have trimmed down the code and have it running with "Mysensors" library but I had to chop the code right back to bare bones to get it to run. Even using the development train for Mysensor there is barely room to transmit 5 paramaters. The floating point math is burning lots of code space. I am thinking to try the ESP8266 board. |
| 26 feb 2016 13:08:18 | Arduino wattmeter | Amir | Hi Freddy, Good Job Nice Project ... It is possible to do this project with Arduino UNO R3? If yes, Could you send me the diagram and code? Or Give us an Article with that topic! Best Regards |
| 23 feb 2016 16:54:02 | Arduino wattmeter | Freddy | You're right. The article is corrected. Thanks. |
| 22 feb 2016 20:56:33 | Arduino wattmeter | Wolfram Fischer | Freddy, I have found an error: you said, for Ah Ampere*seconds (As). To convert this in the common used Ampere*hour (Ah), multiply the reading by 3600. it must be not multiply but divide by 3600, right? |
| 22 feb 2016 13:53:57 | Arduino wattmeter | Freddy | Do you still have the error when using the original code and only changing the line "ADMUX = muxCnt | 0xC0;"? |
| 22 feb 2016 12:04:52 | Arduino wattmeter | angel | yes, the calibration values are both positive. We only commented out the code for the buttons, since we only wanted to display the Vrms, Irms, Preal and Energy at the moment. |
| 21 feb 2016 23:35:31 | Arduino wattmeter | Freddy | Yes it supports 4x20 LCD's. You can set the number of lines and the number of characters per line in "Calibration & Hardware Data". The new parameters must be autorange types. I can's write software for a singel user. It would cost me too mush time. |
| 21 feb 2016 22:24:46 | Arduino wattmeter | Wolfram Fischer | does it support a 4x20 lcd too? And would you implement a 128x128 GLCD in Text-Mode with a T6369 Controller if i send you some displays? I have got plenty of them and they can show 16x16 Caracters |
| 21 feb 2016 10:28:36 | Arduino wattmeter | Wolfram Fischer | Hi Freddy, i added kWh and Ah to the parameters, should it be a 99 for autorange or a 100 in paramRange? paramValues[22] = paramValues[12] * 3600; // Ah Charge ####################################################################### paramValues[23] = paramValues[19] / 3600000; // kWh Energy ##################################################################### char* paramLabels[] = {"Vmean ","Vrms ","Vsdef ","Vmax ","Vmin ","Flux ","f (V)","Imean ","Irms ","Isdef ","Imax ","Imin ","Charge","f (I) ","Preal ","S * ","Q * ","Pmax ","Pmin ","Energy","\\x01 * ","time ","Leistung","Ladung"}; char* paramUnits[] = {"V","V","V","V","V","Vs","Hz","A","A","A","A","A","C","Hz","W","VA","var","W","W","J","\\x02","s","Wh","Ah"}; float paramValues[] = {0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0,0}; int paramRange[] = {0,0,0,0,0,99,99,0,0,0,0,0,99,99,99,0,0,0,0,99,99,100,99,99}; // 99=autorange, 100=int-number int paramDigits[] = {4,4,4,3,3,5,4,4,4,4,3,3,5,4,4,4,4,3,3,5,3,7,4,4}; // number of digits |
