with Kodi, touchscreen is only working if x/y resolutions are exactly the same as the screen. Another question: Is the touchscreen function also working with teensy LC hardware?

Hello, I'm also interested to supply my Teensy 3.2 with 1.8V because I want access via the Teensy external 1.8V Hardware. I'm now a little bit confused about your pin assignment, description: "lifted pin 7 to ground, pin 8 to VUSB, and VREG33" on my teensy 3.2 I cannot find for example VREG33...

ah ok. understand, compiling results shows only the memory usage of global variables... To my other question: What can I do to get 30MHz SPI clock? Or how do I set the Systemclock to 120Mhz? + is it possible to store the array to static RAM/flash? instead to the dynamic RAM and have DMA? thanks

what is the max. Array limit for the SPI.transfer function? I just have try some values, I think the maximum is aprox 60'000? with 65000 it is not working anymore?? void color(uint8_t r, uint8_t g, uint8_t b) { writecommand(0x2A); //x pixel-position anfahren writedata(0x00); //start-position...

hmm thankyou. At the moment I try to write from an array with 240*320*3 Bytes x-D ...with SPI.transfer(rgb, 0, sizeof(rgb)); ... but it doesn't works as expected. :-(( I think the spi-function cannot handle such big arrays?? Can you confirm that? My setting, 96MHz (overclocked), SPISettings...

thank you that works... but unfortunately the SPI speed is still not such high as expected. I'm writing to a 240x320 Frame-Buffer from a Display. I think that the SPI transfer functions still has some delay between every byte or between every third byte.. :-( Is there another function, or...

Hello, I need to transfer via SPI many bytes at once and without delay between every byte. If I do: SPI.transfer(byte1); SPI.transfer(byte2); SPI.transfer(byte3); etc.. I have a delay of aprox 500ns between every bytes... with follow SPISettings settingsA(30000000, MSBFIRST, SPI_MODE0)...

I am not sure about that, respectively how to check that on KODI. Is "Stylus usage" Multitouch too? What I know is if I use the Pictures/Slideshow Function on KODI I can zoom, and rotate the Pictures with the (two) Finger - so it's recognizing Mulittouch ..

I suppose the Dell P2314T ,which this Touchscreen Function are based, is not really a new Touchscreen? My USB Touchscreen with the Atmel Controller I think is a much newer Generation. So maybe that would be the root cause why the touch-function are not working on KODI with Raspberry. Maybe if...

thanks for the reply. I download the latest code from jz11... so if I see and understand that correct, your new updated USB Functions already works with Android? (without modify of your descriptor or something else...) As Android is based on ARM processor I maybe must find out the used driver in...

Hello again. I will post asap more about your great touchscreen function :-D:D but I have still another issue; I don't know If you know KODI? However, KODI respectively OSMC don't use the X11, they use GLESv2. So because of that or according people on the forum some USB-Touchscreen (and your...

soo I really don't know how to be thankfull for your works - it's really amazing it works like a charm!!! :-D :-D I made first picture, I have also other display with goodix, cypress and now I can simply implement it with raspberry without need of search/make complicated driver build kernel on...

woooow, that looks great :-D !!! I will test that ASAP, I think today evening.

any update? Please note: Your Hardware looks the only one with easly configurable Multitouch in the market. I think that is a very advantage and multitouch are more and more requested...! So it would be really appreciate if that will work on linux.... let me know if you need other support? I can...

hmm thankyou, in May 2016 in the other USB Touch Thread Member "Ivartaim" reports follow: Hi! I have been playing around with the following code using the new functions. Using a teensy 3.0 and samsung galaxy s6 with android 6 I have one possible bug report and two possible suggestions. it could...

Dear Paul, could you already reproduce my problem?

Sorry, I didn't realize that it would be helpful to post the code. But please find new thread: https://forum.pjrc.com/threads/49128-TouchscreenUSB-release(finger)-Touch-freezes-bug-with-Linux Anyway, in previous posts you can see that there are other people with difficults regarding the release...

Ok. hope you will find a solution because I think with that I can make every capacitive Touchscreen working on every Platform without the need of build kernel and adapt driver etc. Please let me know if you need more infos or if I can test something more? thanks.

so now I have updated to 1.8.5, 1.41-beta3. Still the same, and you don't need a Hardware / Touchscreen to test it, with follow code it's the same (just Touch Emulating): const int LED = 13; float mtmax = 32767.0; float screenW = 2560.0; float screenH = 1440.0; int i=0; void setup() { //...

oh :-) now I am very happy to get a feedback. I use Arduino 1.8.2 Software / Teensyduino 1.36 My Code/your USB Touchscreen Functions works properly with Windows 10. With Ubuntu 17.04 on a x86, 32bit System the touch/mouse symbol freezes after the first release. With current Raspian Jessie (with...

Hello, on teensy 3.2 there are two USB HID Touchscreen Emulator functions: TouchscreenUSB.press(finger, x, y); TouchscreenUSB.release(finger); see also: https://forum.pjrc.com/threads/32331-USB-HID-Touchscreen-support-needed Unfortunately that works for me only on Windows, but I need it for...

I am dissapointed about the feedbacks? Touchscreens are more and more common and important today... so I am surprised about the less feedback. I have also a USB Touchscreen with Atmel Controller mXT1188s, and that Controller works without Problem on Linux / Raspberry... so I guess that your USB...

thanks, but where can I find that open driver, and how difficult is it to port? Maybe it's already included on Raspbian? It looks that some USB touchs works and some not :-( thats crazy. But however, I have no idea how to install or port driver on linux or something like built kernel. I don't...

no help? I am willing to pay for that! I wrote a Code on the teensy compatible to Focaltech, Goodix, Cypress and Ilitek I2C capacitive Touchscreens which converts the I2C touchscreen data to USB data with your press and release function and that works very good with windows OS but not with...

Hello, I have bought 15pcs teensy 3.2. Touch Simulation is working fine on Windows unfortunately Raspberry/Raspbian OS has problems with the release function. I now have asked to add support for teensy, see: https://github.com/raspberrypi/linux/issues/2336 Is there something I /we/ teensy can...

phuu, that looks not easy, I just had a quick look on the reference manual: https://www.pjrc.com/teensy/K20P64M72SF1RM.pdf I assume I most change something in the SPI.h file - and FMSZ? inTransactionFlag = 1; #endif if (SPI0_CTAR0 != settings.ctar) { SPI0_MCR = SPI_MCR_MDIS |...

Hello, TFT/Display Controller sometimes use a 3-Wire 9bit SPI Interface (9 bit = command/data). Does somebody know if this 9bit is available on the teensy 3.2? I have checked the SPI.h... there I see only the possibilty to transfer 1x, 2x, 3x etc. bytes, but not exactly 9bit. thank you

so the answer is this here: https://forum.pjrc.com/threads/32331-USB-HID-Touchscreen-support-needed?p=103689&viewfull=1#post103689 https://github.com/PaulStoffregen/cores/commit/42cbdc49c067b762836c7acd95e41115db444880 the function are: TouchscreenUSB.press(finger, x, y)...

I want connect a touch-panel with the I2C Interface to the teensy, write my own code to read the coordinate and then I want transfer the data over the USB. So my question: Is it possible? Which function can I use to transfer the data? I think with "mouse move" it would be difficult because I...

sorry, I think you misunderstand me (sorry for my english). I try again: If I want connect a touch-panel with a I2C Interface for example to a raspberry pi (raspian/linux os) almost touch-driver is missing. So I have to write a touch-driver for this linux/kernel. That is not easy!. But most...

I am the first time here, maybe you mistake me with another person? However, so if I understand you right send/simulate touch (multitouch) with your teensy is not available or possible?

Hello, from "elmue", (https://www.codeproject.com/Articles/1001891/A-USB-HID-Keyboard-Mouse-Touchscreen-emulator-with) I got the infos that you have implemented a multitouch (capacitive touch) solution (with teensy 3.2 and latest teensyduino). For me that looks a very fast interesting solution...
