CUTOUCH user s manual Warning II Please be careful to not touch the inverter with label DANGER About CUTOUCH is an integration of Touch panel graphic LCD and CUBLOC embedded computer In the recent years there has been increase of use of touch screens in the industrial field But to use one the user required connecting to a PLC and learning to manipulate complex methods in order to use it In addition cost of touch screen has been very expensive Our CUTOUCH is a new type of embedded controller that integrates Touch screen PLC and graphic LCD into one The biggest difference between CUTOUCH and other touch screens is that it s the only Visual Touch screen controller that can be programmed with BASIC and LADDER in the world today BASIC language can be used to draw graphics and print characters to the LCD and receive input from the touch screen before processing the x and y positions Sensor input through I O turning relays on off AD DA conversion and RS232 communication are very easy to implement in comparisons to traditional non BASIC PLCs With the LADDER LOGIC side of CUBLOC the user may do sequential processing and real time logic processing as in traditional PLCs CUTOUCH has a flash memory for BASIC and LADDER programs A serial port can be used to download and debug After downloading is done it can run in a Stand alone state If you are thinking about developing a device that uses a touc2. this buffer fills up and data is sent to it the data could get corrupted In order to avoid these situations you can use the WAITDRAW command to wait until the buffer has enough space before sending graphic commands If you need to draw graphics repeatedly we recommend you use WAITDRAW to avoid situations where the LCD might get blurry or received noise This command can only be used with CUTOUCH Touch Pad Input Example You can use SETPAD ON PAD and GETPAD commands to find out which menus were pressed from the user All PAD commands are geared for receiving and processing touch input We can use ON PAD interrupts to receive touch inputs The following is an example program that uses the touch pad DEMO FOR CUTOUCH Const Device CT1700 Dim TX1 As Word TY1 As Word Set Pad 0 4 5 1 Activate Touch PAD Input On Pad Gosub abc 2 Declare pad interrupts Do Loop abc TX1 Getpad 2 3 Interrupt Service routine TY1 Getpad 2 GILSEN TH ETIA 4 Draw a circle where it h was touched Return 1 SET PAD 0 4 5 This command will activate the PAD inputs Syntax SET PAD mode packet size buffer size CuTOUCH has a separate touch controller that will sense touch input and send back to the CPU through SPI protocol This touch controller will create a signal that is equal to mode 0 MSB RISING EDGE sampling Input packets are 4 bytes each X and Y each get 2 bytes Buffer si
