rescue me from this ........

>i will stick up with a resistive touch screen

>how can i interface a touch screen with a mc(specify which one to use)

>i have a idea of making a robo which wil move in the pattern drawn on the touch screen......is that possible

-----for example if i draw a circle my robo should make a circle

>i am not at advanced stage just a beginner with some knowledge on avr so what way i can make my robo come true

>i have googled for a long time i havn't found any sources........provide me if u have any

Hi shyam,

first i like to ask which touchscreen ur using... resistive touch means.. is it a HMI or touchreen module..

if it a HMI u can directly.. communicate with standard rs232 or rs485 hardware.... u can control the robot by entering data... one thing keep in mind... if u want to draw the graphical or gomentrical.. inputs means u have to try for a diff vendor.. to purchase a HMI..

i dont know what HMI means but i am using a 4 wire resistive touch screen

if it a HMI u can directly.. communicate with standard rs232 or rs485 hardware....



can't i doit through a microcontroller,with out using a pc,actually my pc doesn't have serial ports...

if u want to draw the graphical or gomentrical.. inputs means u have to try for a diff vendor..



can u mention the vendor,i want to do exactly what u meant...
