How can I monitor the state of the ON/ON button on the Teensy 4.0? I need to display a message on the TFT when the button is pressed. Is it possible?

Hi, I need to get string data from XPlane. I tried use FlightSimData type but not working. // Type declaration FlightSimData GpsNavIdAircraft; //onChange fuction void update_display_gps_nav_id(char *val) { ???? } void setup(){ ... GpsNavIdAircraft =...

I need help with the SerialFlash I am trying to adapt Pepijndevos's project (https://github.com/pepijndevos/bicycle_gps), which reads data from a binary file representing a map using an RTree. The project was developed for the Arduino Mega, and I am trying to use a Teensy 4 with SerialFlash...

Thank you for your answer. I decided to use the example CopyFromSerial.ino, making some changes to the original code and some modifications to rawfile-uploader.py to make it work as I needed. Since I'm using an ILI9341 TFT display, I modified CopyFromSerial.ino to show the information on the...

Hi, sorry for the previous post. The solution was to specify the SPI bus in the code line. SerialFlash.begin(SPI2, FlashChipSelect); Thank you.

Hi, I'm working on a project using Flash Memory W25Q64FV chip. I'm using the SerialFlash library on a Teensy 4.0 SPI2 bus. I downloaded the current version of the TransferTool library available at (https://github.com/mamuesp/TeensyTransfer), but it seems to only work on Teensy 3.x versions...

Hi everyone, I'm working on a project using Teensy 4.0 and two ILI9341 TFT displays whith library ILI9341_T4. The first one is connected to the SPI.0 port (CS:10, MOSI:11, MISO:12, SCK:13), and the second one is connected to SPI.1 (CS:0, MOSI:26, MISO:1, SCK:27). I also need to use a W25QXXFV...

Thank you Peter. I will try to explain the problem better. The drawEFIS () procedure needs approximately 40ms to complete. It reads the values ​​of the variables, prepares the buffer and displays it on TFT. The mavlink MAVLINK_MSG_ID_ATTITUDE protocol message is sent by the flight controller...

Hi everyone!! I'm working in a EFIS emulator project to RC airplanes using the ILI9341_t3n library. I am having some performance problems in the processing of messages via the serial interface when use updateScreen. For some reason, when using updateScreen or waitUpdateAsyncComplete, the serial...

Is it possible to do something similar as done for Teensy 3.2/3.5/3.6 described here: https://github.com/Sepp62/JetiExBus/...ensyReadme.txt with a teensy 4.0 ? Post copy: Here

Hi guys :D I'm so happy to show you my RC EFIS project. Materials - Teensy 4 board!!! (Thanks Paul!!!) - Flight Controller - APM 2.6 Look the video teste here!

Thank you Michael

Can I to connect audio output pins #2, #6, #7 or #9 from T4 to PropShield's AudioIn pin?

Thanks Paul, I would like to use the library in a project. I will wait for the library update.

I would like to know if the FreqMeasure end FreqMeasureMult library work Teensy4.x?

What does the best input pin from Teensy 4x to use with the FrequencyTimer2 library?

Hi, I would like to report a small bug in the fillTriangle procedure in the ILI9341_t3 and ILI9341_t3DMA libraries. The variables sa and sb lines 842 and 843 respectively have an overflow when the triangle exceeds a certain size. The variable type must be overridden from int16_t to int32_t...

Thanks Frank, Thanks for your answer. I remove tft.refresh() and I put tft.refreshOnce() after update buffer with new data, but unfortunately it did not work, the displays stopped showing the pictures. Only worked correctly with tft.refresh(); Would you have another idea for solving the...

Hi every one, I am using Teensy 3,6 and TFT ILI9341 and ILI93141_t3DMA library to do RC EFIS emulator. I'm having problems with flickering on the display. http://youtu.be/o3HQrxk5x28 I'm using a similar technique to play videos...
