    FlexIO SPI - Now support for DMA/Async transfers... I now have an implementation of the transfers that uses DMA. I have it all setup using same API as normal SPI: bool transfer(const void *txBuffer, void...

    @manitou - Flexio PWM sounds like fun. Maybe have to integrate in some time... Right now hacking up my set of FlexIO code to enable DMA on the SPI. Right now setting up code to try to request shifters that have...

    But I have several of these gadgets sitting around as I needed them for testing out USBHost code... Actually the one I fried, was one I just purchased a month or so ago as Lady Ada reported that it was not working with...

    @defragster - Running your version of the sketch now... In order to make it easier to read without magnifier, I changed setTextSize(2) instead of 1 ;) I just screwed up and was thinking I was plugging in my USB...

    Sounds like it must have missed one or more interrupts. That is if there is a delay of time before it services a TX request ISR, the SPI output will have a gap in time. If however it waits too long to service an...

    Again not sure why TCA9548 would not work with Wire library but would with i2c_t3? But these two libraries can not co-exist in the same sketch either directly or through libraries. That is if you include i2c_t3,...

    Thought I would try to shorten the test to just run the scrolling flakes... So after the initial screen begin and erase, it then just called testanimate... I changed the code to also output a loop counter on the...

    Sorry, I meant to update the comment. As noted in the posting I had the pin numbers and caught it when I was rehooking mine back up, but forgot to update comment :0 Looks like some of the Flex stuff needs some more...

    Thanks @defragster, will play some more later today :D Right now Trying to understand how to use the DMA with the FlexIO subsystem... My quick understanding is to use DMA for one of the 4 "channels" like on...

    Thanks @defragster, Looks like there may be some form of stress issue and/or timing issue. With the code like: display1.displayAsync(); // Show the display buffer on the screen while (...

    I agree, I just copy and pasted from the T3.x function like what is in core3/serial1.c. My guess is there is a slight possibility in the SerialX.write() case, that maybe there could be a usage case where maybe the...

    @defragster - I will play with it and see what you think. Also I need to play with your SPI test program... Was gone some of the day and then played around some more with my hacked up Adafruit_SSD1306 display driver...

    I guess the real question to me, is, what should the yield do when the priority is inverted, like you mentioned. That is in normal cases, the calls like Serial1.flush() will not return until the last byte that was...
