CAPSENSE™ & MagSense Forum Discussions
從下圖我們可以看到, 當從Active mode跳到Look for touch mode的時候, 中間是沒有下command的,
另外, 從Look for touch mode跳到Look for proximity mode的時候, 中間也是沒有下command的,
想請問以上這兩種模式的相互跳躍的機制為何呢?! 是可以被configure的嗎?! 還是這兩種模式之間的跳躍的機制已經是被固定住的呢?
想請問以下第七章談到MBR低功耗設計的注意事項, 而在7.1節中一開始就提到CY8CMBR3xxx 的工作模式:
MBR總共有5種工作模式, 想請問的是: 是不是這5種操作模式的每一種工作模式都有其對應的低功耗模式操作呢?!
我的意思是說, 每一種工作模式的低功耗操作都不盡相同, 對嗎?!
比方說: deep sleep mode是一個獨立的低功耗工作模式, 它並不是歸屬在其他工作模式之下的!!
另外, 就是規格書中還有一個ultra low power,
請問這個ultra low power似乎沒有被明確指出它是在以下5種工作模式的哪一種, 所以這邊也有點疑惑,
I'm sorry that I have some confusions about MBR(CY8CMBR3106S). Hope you can help me to clarify it.
#1. How to treat those unused pins of the MBR(CY8CMBR3106S)?!
Could we keep them floating instead of connecting them to ground?!
#2. About the pin 18 of MBR(CY8CMBR3106S), why this pins18 have to be connected to ground?!
#3. Do you have any power consumption data about MBR(CY8CMBR3106S)?!
Thank you so much.Show Less
Our customer is planning on a new IoT device project, battery operated and wants to use capsense to (touch) wake up and also using capsense for device functions control (exact functions via capsense not fully defined yet).
Our customer wants to know first if IFX has feasible capsense solution as the material of their IoT device is quite special !
The base material of the device will be silicone, and our customer will also have a detachable sleeve/jacket on the device which is made of cotton or fleece type of material. The base silicone material will have a thickness up to 4mm. The cotton/fleece sleeve jacket will also have a thickness up to 4mm. Altogether up to 8mm (under 1cm).
Our customer is asking if any PSoC4 with Capsense can support/operate on both :
a). just on the base silicon material (up to 4mm thickness)
b). on top of the base silicon material + the cotton/fleece type of material (overall up to 8mm thickness)
Can the PSoC 4100S Max and/or the new PSoC 4000T (fifth-generation CAPSENSE™ and MULTI-SENSEtechnology) meet the customer's requirements ?
If yes, please help to advise which specific PSoC4 part # and please also help to provide any relevant application note(s).
Much appreciated !Show Less
For continuous integration we need to simulate sensor touches with an electronic input. Is that possible?
I made a two layer PCB using the CY8CMBR3116 touch controller. I followed all the design guidelines and in particular made the top layer hatched ground plane with 25% fill and the bottom layer hatched ground plane with 17% fill.
The board works, with one odd problem: when I place the PCB on a plastic surface (ABS) so that the bottom layer is against the plastic, then when I press one of the touch sensors, it registers many fake / ghost touches that aren't actually happening. It seems like the smallest bend in the PCB, pushing it closer to the plastic, causes these incorrect button presses to be registered.
When I put some thin packaging foam between the PCB and the plastic, then the problem goes away and the sensors are very accurate.
So I created two new versions of the PCB, with 45% and 65% hatched ground plane fill on the bottom layer - but the problem still happens.
Does anyone know why this could be happening? Could any EZ-Click firmware settings help fix this? Any help appreciated, thanks.Show Less
Please tell me about the latched_button_stat register latch mechanism in the Cy8cmbr3xxx series? When is the device
Go clear LATCHED_BUTTON_STAT? Thank you.Show Less
I use capacitive touch buttons with the CY8CMBR3116-LQXI components.
The datasheet recommends parasitic capacitances (Cp) between 5 pF and 45 pF for buttons.
I measure, with the EZ-Click 2.0 software, Cp between 2 pF and 4 pF. Is a Cp value below 5 pF a problem?
For information, I use buttons with a diameter of 9 mm and trace lengths less than 40 mm. The width of the traces is 7 mil (0.17 mm). Button-ground clearance is 2mm (because the glass thickness is 5mm). A hatched pattern is at the top and bottom (2-layer PCB) and it is connected to the SH pin.
Hello, we are interested in extracting human signs from millimeter-wave radar. After reading the information, we purchased Infineom's BGT60TR13C and downloaded some related components. Can this radar chip currently have a demo to measure heart rate or breathing?Show Less
