how to use tlc 548 adc
Hi, I am currently doing my final semester project and hope to get some help from here. The purpose of my project is to design, built and test a low-cost electronic system that will analyze the characteristic of analogue waveforms. It must able to measure the frequency, mean value, rms value, peak-to-peak voltage and duty cycle of an analogue waveform.The processed results can be selectively displayed on a LCD screen. The electronic system will be implemented primarily through the use of an analogue circuitry (that will make sure the input voltage falls between 0 to 5V), an A/D converter, a PIC16F628 micro-controller, and a LCD Alphanumeric 20 X 4.
:arrow:
Is it possible to display the results for large input voltage range? ( i.e. -240V-240V) :?:
What additional components OR any circuits do I need to in order to build this project :roll:
I am not allowed to use a built-in ADC PIC in this project, so which type of ADC chip is suitable for me? :idea:
Is there any website that related to my project and where can I find the programming code for my PIC for this project? :!:
Thank you very much!!~ Your help will be truly appreciated
