    Real time serial data acquisition

    Hi I wish to take the samples from pic16f877a,4Mhz HS( if it is given a sine wave input) and plot the same.I am giving 230vp sine wave 50hz as input and transformed it into 5v range and level shifted it into positive voltages. This is my code // Loop variable...

    disturbance detection from a signal using microcontroller

    I have done the coding in mikroc,and after that i run hyperterminal,thereby captured the values.My signal is 230V 50Hz and i m using pic16f877a adc 10bit delay of 10ms // POWER QUALITY MONITORING SYSTEM // LCD module connections sbit LCD_RS at RB4_bit; sbit LCD_EN at RB5_bit; sbit LCD_D4...

    disturbance detection from a signal using microcontroller

    hi I want to calculate the duration of a disturbance signal,what i have done so far,i coded the program for adc interfacing with pic16f877a,capture all the samples and stored it in a text file. for disturbance detection,i used wavelet decomposition in matlab,simulated the disturbance and...

    Mikroc adc uart problem

    I wish to display the adc values coming from serial port to hyper terminal.I have created a level shifter circuit with sine wave (5 vp-p) and 2.5 v dc as inputs and input the data to the pic 16f877a wat i m getting from the terminal are in the range of 2.5-8.6v,since i gave input below 5.0v...

    Rms voltage calculation mikroc code

    why i am finding the rms voltage,is to calculate the voltage sag a disturbance occured in the supply using rms voltage method.In this process,the voltage is to be compared with the reference voltage
