hello , i have a question about touch screen FT5302 . As in all touch screens when i touch a point on FT5302 it produce an interrupt that i use it to create an I2C transfer for giving coordination it give back o me. (because my controller is master and touch is slave) . in its data sheet(https://www.newhavendisplay.com/app_notes/FT5x06_registers.pdf) there is a table that list its registers and when i read 6
bytes i can reach to desired coordination but a addition of this coordination it give back some other information that i do not know what they are and they harm my work . i guess i should read a number of bytes and then terminate i2c and do not know how many byte should i read . appreciated if some of you guide me .
thanks
I don't see the problem.
You may set start address...and you may read as many bytes as you like.
If you don't want to read 6 bytes, then simply don't do it.
Each register has it's own address.
What registers (addresses locations) do you want to read?
