Forum Post: RE: Resistive Parameter of TSC2006
Hi Andy, Thanks for reply. My customer request as below. They wants to improve the touch sensitive and then he think that should be a sensitive parameter who can adjust by himself. His end user might...

Hi James, In my perspective, the sensitivity is mostly determined by the physics of the resistive touch panels the customer is using now. Basically if there is no stable contact of the two ITO layers...

If the proper touch panel is confirmed, I would suggest the customer try to increase the report rate so that the sensitivity might be improved. I can comment more on that if necessary. Andy

Hi Andy, Current Touch panel can't be changed and it is working well when users touch it by finger or touch pen, but it is not sensitive if they take gloves on hands and then touch it, while they have...

Hi James, As I clarified before, if this sensitivity issue is caused by the loose contact of the two ITO layers on top and bottom sides, there is nothing that the TSC2006 could do to improve that....

Hi Team, I was wondering what parts that we have that may be appropriate in a situation where one needs to interface with a touch screen wearing leather gloves. I imagine a resistive screen would be...

Hi Akash, You are very right. Resistive touch controllers are the right choices for your application. Regarding how to choose a resistive touch controller, the first question is will you use a 4 wire...

Hi Team, I'm looking for a cross for the AR1100. Under the parametic search, I didn't find anything that was specifically USB and/or RS-232. Do you have a recommendation for anything that can replace...
View ArticleForum Post: Spurs appear on I2C SDA of TSC2007
Hi, I found spurs appear on SDA. Blue is SDA, yellow is SCL. It always happened on the falling edge of 8th or 9th clock, or before the 1st clock cycle. It didn't bring error on data communication, but...

Hi Jared, Sorry, I think I missed this post for some reason. Basically, TI doesn't have any resistive touch controller that could replace the AR1100. All the resisitve touch controllers from TI support...

Thanks Andy, Are there any touch controllers that can compete with the AR1100 that are I2C or SPI based? Thanks, Jared
View ArticleForum Post: RE: Cross for AR1100
Hi Jared, It depends on the sensor type. None of TI resistive touch controllers is able to support 4, 5 and 8-wire touch screens at the same time. For 8-wire touch screens, no touch controller from TI...

Has anyone attended a TI Tech Days Seminar in the past? I can’t tell if the contents will be technically rich or a thinly veiled commercial for TI product lines. There were a few items that caught my...

I'll give you an "insider" perspective, though I hope some community members will chip in with their thoughts too (good or bad!). The content is generally chosen based on a particular market, i.e. the...

Thanks, Brad. It's good to know that there is some good technical content. I had reviewed the abstracts, but wanted to ask to get more of a grounded answer. (Pun intended.) I'd appreciate other...

Hi Di, I can see the similar spike in my office using a TSC2007EVM. According to the i2c spec, the SDA signal can only change when the SCL signal is low; when the clock is high the data should be...

Thank you, Andy. Could tell me where this spike come from and is there any work around circuit to remove it?

Hi Di, I don't have a perfect answer for you now. I may have to ask the designer for this device for a more detailed answer. Technically, the TSC2007 meets the I2C specifications even though the spike...
