    I am getting a little farther with the Picture viewer. I get images displayed but goes away quick.... It has to do with we were using a sort of frame buffer in the output code: The SPI code: inline void writeRect(int x, int y, int cx, int cy...

    Don't remember - thought we had them working in all directions - unless it was only the internal fonts that had issues. May raise other issues - have to hook up the SPI version as a double check.

    I'm still deep in the GUI(ESP32) - Teensy integration. Preset System: supports up to 128 presets (if SD card is present) or 8 if using EEPROM only. EEPROM is still used to hold the 1st 8 presets. Acts like a backup copy, SD cards can fail...

    Ok think I found one issue with the FontTest4 sketch. If you comment out this line (156 or so) else tft.setFontDef(); and replace with //else tft.setFontDef(); else {} no issue with rotation - draws cleanly. fontDef is defined in the ,h as...

    I should probably also mention the hacky way I'm making it use my driver without modifying any of the QNEthernet source: I put "dot_a_linkage=true" in the library properties and provide my own versions of all the driver functions. So the library...

    Yes, simply buy a Teensy board.

    I can certainly help with this. First, I don’t love the Arduino-functions-are-members-of-a-singleton nonsense. I’ve already started experimenting with turning everything in a singleton into a static function. You can set a MAC address with...

    I narrowed it down to: inline void setFontDef() { _use_default = 1; // if(_portrait && (!_use_gfx_font || !_use_ili_font)) { // _cursorX += _cursorY; // _cursorY -= _cursorX; // }...

    FlexCAN_T4 users and tonton81: I'm having some difficult with FlexCAN_T4 being able to reliably see CAN messages on the bus when it starts up. When there is traffic on the bus already as the Teensy 4.1 boots up, it sometimes can't receive it, as...

    Guess is that with the rotation sketch we are only using graphic primitives which in the RA8876 uses the graphic engine. As for the font - could be which font. So the question is why does it happen with one and not the other - are we calling...

    I used TeensyDebug to trace the issue as far as a call to memset(), which is in a binary library with no debug information so no line number available. Unfortunately the backtrace just told me the stack was corrupt, so I couldn't pinpoint the...

    Until now you haven't said what you are trying to accomplish. I mentioned that you can calculate speed because that is often what one does with a relative encoder. What are you doing with the encoder, and how fast is it going to turn (revs/sec or...

    You don't need to use a levelshifter since the output stage of the encoder you referenced above has "NPN open collector output circuit". See this thread for more info. So just power it by 5V. But do I correctly understand that you want to drive a...

    So what you're suggesting is basically to get a slice of time and getting the speed with delta x / delta t? My question would this result in any steps being missed? And to then translate this to replicate the movement on the stepper would I just...

    Yes, I do have them with INPUT_PULLUP. Unfortunately the encoder I have is locked down with another project but I believe it is that same one you have there so I expect I would get a similar output. I've uploaded a picture of the encoder and it...
