    Hi ZoidiusInfuser, I have played around with at least three different ways to control these servos using Teensy 3.x boards. a) Simplest - Simply connect up to TX pin of Serial Port. There is a half duplex sort of...

    You might want to take a look at my ili9341_t3n version which supports the DMA buffering mode as well. Although I have used mine more in a different way then you had done with your _dma version in that I did not...

    Yep - Sorry I thought I responded earlier, but I guess I never hit the post button.. I have found that my apps that use the USB Serial object does not run without the Serial monitor running. Including things...

    The main issue about porting ili9341_t3 is not that there is not a FIFO, but that the fifo does not include information about the desired state of up to 4 Chip select pins, which we use to encode both the CS, but more...

    Maybe it is interacting with my changes to HardwareSerial. Also there is/was problem with the SerialX.flush() function, as I was not properly looking at TC status flag. Fixed in my current branch I just pushed up,...

    Sounds great: Another generic question maybe already answered? I would like to finish putting in the RS485 support into HardwareSerial. So the question is how to do the digitalWrite HIGH and LOW... Obviously I...

    Hardware Serial testing - Loop back test: #define SERIALX Serial2 void setup() { while ( !Serial && millis() < 4000 ) ; pinMode(13, OUTPUT); pinMode(2, OUTPUT); /* pinMode(3, OUTPUT);

    Hardware Serial - Created a PR with current WIP - so you can try it out. At least I have Serial1 working with Loop back test. Lots more work to go! Kurt

    Sorry I have been a bit slow here, hopefully will have a PR today that has some of the HardwareSerial stuff working... Finally got Serial1.read() to work :D So far only in the test program. I need to build some...

    Actually it has been a long time, since I did anything with RC servos. As mentioned you can configure the library for your servos. Back when I was using RC servos, the majority of the time, I used either an arc32 or...

    Note: I have not used RC servos for a long long time now. But back then I used to use two different approaches to controlling the servos. The Basic Micro ARC32, which was discontinued a long long time ago)... Or I...

    General question: Wondering about how you are handling setting/clearing bits in registers without bit banding? As M7 chips do not have bit banding. It does appear they have setup some registers to handle this, by...
