Hello,when I measure voltages less than 1v I have a problem. The values in the LCD never are less than 1v.For example, if I have in the analog input 0,45V I have on the LCD 4,5V.Do you have any idea why this happens?Thanks.great tutorial.
Hi. I think there is some bug in the FloatToStr() function. Try to ask in mikroC forum (" forum.mikroe.com/ ") many people have complained about it. Use sprintf() function to convert float to string instead of the FloatToStr() function. So replace FloatToStr(mV, txt); with sprintf(txt, "%2.2f", mV); But please note sprintf() doesn't work with PIC16F series, use it with PIC18F series. Let us know if it works.
very well!! Thanks you.I thinks that the problem is the 0 to left. The compiler depreciate that 0 and then when show the 4 characters move the string one site to left and don't show the 0.
The decimal point could have been more than that even though we limited it to 2 digit in this example. Yes voltageText[5] could do the job in this case.
great tutorial, the library says that "This function doesn't work with the external voltage reference source, only with the internal voltage reference. " in your adc input section consider that i use 3.3v source instead of 5, i will get a better resolution so will it be good? Thanks
@@StudentCompanion no at its at 5v , so for me what is happening is the current sensor gives outputs in uA so i thought better resolution would be better
You can't use 3.3V while your PIC is running at 5V because that library doesn't work with external reference. You can use the ADC by accessing directly the SFR registers of your PIC. Read your datasheet to learn how to do it: download.mikroe.com/documents/compilers/mikroc/pic/help/predefined_globals_and_constants.htm
Hi. How can anyone help when you are too broad with your question? The problem could be code or hardware or both. You are not saying exactly what is not working. Whether your code is not compiling or no value is received or wrong values. Be specific and you might get assistance.
@@StudentCompanion Thanks for your replying. when I am using pic 18f452 or 16f877 microcontroller, I can read ADC value which showing my LCD display. But when I am trying to read ADC value using the pic 16f72 and 16f73, it did not return any ADC value. I am using mikroc for pic adc library for reading the ADC value.

@@RazibShahadat Are you connecting the analog sensor/potentiometer on RA1? The only other thing that could be wrong is your configuration bits if you did not set them properly. In Edit project, make sure the oscillator selection is set correctly, correct oscillator frequency and those other bits are set correctly.
Great tutorials! The best I've seen so far. Please keep it up. I have two questions: 1. Why did you add the line "voltageTxt [4]=0;" 2. How do you know that your voltageTxt string is supposed to have a length of 15?
Thank you for watching our tutorials and for your feedback. much appreciated. 1. We just wanted to display our value to 2 digits decimal point, the 3rd digit if any should be 0 and ignored. Two digits before decimal points and two after decimal points (= 4 characters array) 2. According to FloatToStr function conversion requirement, the Destination string should be at least 14 characters in length. You can learn more at: download.mikroe.com/documents/compilers/mikroc/pic/help/conversions_library.htm#floattostr
How can I use the ADC_Get_sample to get 230 AC volt as my final result displayed on my LCD. Also, how can also use the above coder to get current value of 230 AC volt displayed on my LCD. I don't know what next to do after that point. Thanks
Hi. A PIC can only work with DC voltages from 0 to 5V. You must find a way to step down your 240 AC volt and rectify it to DC. This low voltage can be ready then you can multiply the read value with the step down factor to get the full voltage value.
Thanks for your reply. I used Transformer to step down 230 volt to 12 volt, then used rectifier to convert the 12dc volt to pulsating dc and finally with capacitors and 7805 IC, to get 5volt dc as output. The major issue I am having is which of the step down factor should I use to multiply the reading ADC. Is it the capacitor values or others. my capacitor values are 2200uf and 0.1uf. my transformer step down values in henry (Primary = 1H, seconday = 0.00137H. the rest remains same in proteus.
When you step down a voltage from 220v to 12v, by how much did you step it down? That's the simplest question you can ask. Read the comments on this thread to learn more: www.microchip.com/forums/m/tm.aspx?m=76012&p=1
For accurate measurement a transformer will not always give you the correct accurate values because the input voltage is not always stable. Microchip application notes describes energy measurement in details. You can search those application notes.
Question Have programmed the new PIC18F26K40 chips. I have the EasyPIC v7 board. I can't get the ADCC or the Euart to work. Would be helpful for a video on this chip. MPLAB wouldn't do it either. Thanks my friend.
+James Cullins Are you sure you are setting correctly all the jumper switches of EasyPIC v7 board to use this PIC? The EasyPIC can program many different types of PIC in different package sizes and I think the default is set to use the 40 pin package. So check if your package (28 pin) us selected correctly

Hi love your videos. I ran the simulation but the LCD display is wrong when the voltage is less than 1V. For example if the voltage is 0.95V it will display 9.5V, i think it's just an error on how the float is formatted for the LCD. Could you give insight on this. Thanks!
Hi the error is in the proteus simulation. The value is still correct if you think about it it's just the decimal that is wrong. It doesn't output 0.0V to 0.99V

how to increase the accuracy of the output
+Devesh what do you mean by increasing accuracy? This PIC has 10 channels of 10-bit ADC. You can't get more than 10-bit unless you use a different PIC which has higher especially a dsPIC or a PIC32. Or you can use a specialized ADC chip.
see I am using lm35 and when i send a analog signal for eg 49.56 then on the LCD I get something 49.00 or 40.13 but not the accurate value
+Devesh what do you mean by 49.56? Is that a voltage? Because the LM35 doesn't produce such high voltage. You might be losing accuracy in your calculations. It's got nothing to do with the ADC resolution of the PIC.
its temprature control
+Devesh that's more with your floating point calculation when you are converting your ADC value to temperature i think.
this my choice always 24/7/360
