hi all,

Where should i refer for uezgui-1788-70wvm kit contained capacitive touch screen controller details. Is it FT5026 or some other controller?
We are communicating through the I2c serial interface, suppose we assume FT5026 is our controller. Then in this datasheet they gave some modes. For example we will take operating mode some registers are there. For single touch event only one single X and one single Y values are generated or multiple values are generated for single touch??? or multiple events occur?? if we touch continuously on single point,maximum how many values it can store??

thanks in advance

hi,
i understood that uezgui-1788-70wvm contained capacitive touchscreen is directly interfaced through I2C to LPC1788. So we directly read the X,Y co-ordinates using I2C1_read operation. But, what is the I2C device address for this uezgui-1788-70wvm module, where we can get touch co-ordinates. Means at which specified memory location we should collect these X,Y co-ordinates?? Is this I2C gives single X and single Y values or multiple ?? Is this the right place to asking about this capacitive touch screen?? If no, can anybody please tell me where should i get information about this thing (uezgui-1788-70wvm ).

kindly answer.

Is ADC is required for uezgui-1788-70wvm contained capacitive touchscreen co-ordinates reading?
