Part Number: TSC2003 Other Parts Discussed in Thread: TSC2007
Tool/software: Linux
Hi everybody
We designed custom hardware including the TSC2003 controller. We are dealing with the following problem. Occasionally, the TSC2003 reports an erroneous press…
Hi Johan,
Sorry for the delay and welcome to our e2e forum! Have you made any headway yet? You would have to turn on the switch drivers to measure the X/Y pins. What have you done as an initialization sequence for the TSC2003?
Part Number: TSC2003 Hello,
I am trying figure out how to read temperature using this chip. It looks like I implemented my I2C drivers correctly because I am able to measure X and Y okay and I am able to implement touch screen feature. But I could not…
Part Number: TSC2003 RE: VB1 and VB2 pins.
Referring to the supposedly non-automotive TSC 2003, i2c touch screen interface (not the Q-1 suffix automotive version): No where, that I can find in the data sheet, does it refer to, or tell one what to do with…
Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: TSC2003 Hello,
I also posted this on the touch forum but I figured I might get some feedback here too since I am using the TM4C1294.
I am trying figure out how to read temperature using the TSC2003…
Hi Arthur,
Can you please share the "device marking" identification document/ link, so it will be easier to identify the revision of device
& what about the TSC2003 response to same issue? does this device having more immunity?
Other Parts Discussed in Thread: TSC2003 I have a customer who would like to use the VBAT1 and VBAT2 on the TSC2003 to measure up to 32Vdc. Since there are built-in resistor voltage dividers on each input, could he simply just put a 47.5k ohm resistor between…
Hello Higa, the biggest difference that is mentioned in comparison table is the max sample rate: 154 vs 100 KSPS, of course the package and number of pins are also different. There are other differences such as TSC2007 has touch non-detection mode.
From…
then i have to ask about this:
"There is not any specific power up sequence requirement for the TSC2007 (Revision C or later). That is: the power supply to TSC2007 VDD and to I2C pull-ups can be brought up in any order"
from: SLAA364, "Migrating…
