Hi,I'm wondering what the purpose of the series resistor (Rs) is for touchkey applications. I have found in documentation and presentations that it is for extra ESD immunity, but can someone be more precise? Thanks,CT
HiI'm working on touch sensing feature of stm32f051,,but I have a big problem that every board that I assembled has different thresholds for its sensors(the component are the same) and I can't have a unique code and each time I have to change thresho...
Hi all,STM32F303 is as capability to sens touch which is surface touch principal . I am trying to get the values on STM studio but unfortunately i am not able to see any values on it. there always a flat line. I am posting my code can anyone tell me ...
Hello all, i have a problem with the STMTOUCH_DRIVER to manage a touch button and a slider. I have integrated the library into my code and if i manage only one bank and the touch button all works. In Touch.c and .h there is the init and main function...
I have designed an STM32F04 based board with a shield, 4 touchkey sensor (round electrodes with a 10mm diameter) as well as 2 linear sensors. These are using the 3 half-ended electrodes interlaced sensor sensors as described in AN4312. Some things re...
Hi,I Have two problem.first : using STM32F051R8Txcant use IO_TOUCHKEY2 at all !, have to assign IO2 to unused PIN and define new IO_TOUCHKEY.(if you need 3 touch you have to set 4 touch in CUBEMX case IO_TOUCHKEY2 doest respond!)second: why STM32F051...
I have written a TSC code for STM32L476RG . I have attached a sampling capacitor of 47nF and have connected it between sampling IO pin and GND. I have another capacitor which I have connected between a channel IO pin and GND. I want to measure the va...
Even though most of you may be relatively familiar with the various types of mechanical controls, the same does not necessarily apply for capacitive ones. So, let’s start off by defining the most basic elements of capacitive sensing.Capacitive button...
Each touch sensor features 2 sets of electrodes: the Transmitting ones (also known as Tx, or the driving electrodes, or simply X electrodes) and the Receiving ones (also known as Rx, or the sensing electrodes or simply Y electrodes).Electrodes are us...
