    Using the co-ordinate information from a resistive touchscreen to play music

    Hello All, I have a 4-wire resistive touchscreen and have interfaced it with a PIC18F4550 uc. I am able to display the co ordinates on an LCD at this point of time. What I wanted to do is using this co-ordinates (0 to 1023) information to control a device to turn it ON. For eg, I would like...

    ADC implementation in PIC18LF4550

    Hello all, I am trying to use the ADC of 18LF4550 to display the analog voltage levels on an 16x2LCD. My code is compiling giving me an out, ADC OUT = 0000 This is not varying as I change the pot. (1k pot used, variable to AN2, one leg to supply, and another leg to GND). Can you help me to...

    Interfacing a Resistive Touch Screen with 18LF4550 and displaying on an 16x2 LCD

    Hello all, I am trying to display the touch positions from a resistive touch screen on a 16x2 LCD using PIC18LF4550. I got a sample code from http://www.pyroelectro.com/tutorials/touchscreen_interface_resistive/software.html I have made few modifications so that I can operate with 18LF4550. I...

    Interfacing PIC18LF4550 to 16x2 LCD

    Hello, I am trying to interface a PIC18LF4550 with a 16x2 LCD display (h as a JHD162A Processor) in the 4 bit mode. I have done some modifications to the code that I got from PyroElectro.com, but, the display shows nothing and am not sure where is the mistake. Could you please help me to...

    Interfacing PIC18LF4550 to 16x2 LCD

    Hello, I am trying to interface a PIC18LF4550 with a 16x2 LCD display (h as a JHD162A Processor) in the 4 bit mode. I am using PICkit 2 for programming which loads the hex code in to PIC. I have done some modifications to the code that I got (this code I got it from PyroElectro.com), but, the...

    APR9600 voice recorder problem

    You are welcome rahray87, about the noise I am also facing the same at that time, I bought a speaker with 8ohm o/p impedance and used signals coming in the range 0-8kHZ. These don't have much noise and don't put the pot on the LM386 to max, test it with oscilloscope, set for different...

    APR9600 voice recorder problem

    I hope you have connected the DC blocking capacitor between ANA IN and ANA OUT. Set \CE=0, \RE=1, will enable playback if you are sure you have recorded data on it.

    APR9600 voice recorder problem

    Check this circuit, I hope it will serve the purpose. Connect a speaker with O/p impedance= 8ohm or 16 ohm
