    I will have to test it, but I am inclined to believe that it works. If it does, that is really interesting. It implies that something is not as it should be in the interrupt logic. The reason I...

    Teensy 3.2 TSI Interrupt

    Greetings everyone,
    for quite some time now I found myself at an impasse regarding the TSI module of the MK20DX256 (aka Teensy 3.2). I try to implement a simple continous capacitance measurement by...

    Using TSI for capacitance measurement

    Greetings everyone!

    I am currently trying to implement a capacitance measurement using the TSI module on the K20 MCU (Teensy 3.1 board). I thought to have grasped the principle of operation, but I...

    Ok, seems I got it working now.
    Another mistake of mine was enabling DMA_TCD_CSR_DREQ, this cleared the request flag and thus prevented any work to be done. In case anyone is interested, I provide...

    You are right about the DMA interrupt. I use it for debug purposes and forgot to take out the NVIC command/leave the ISR in.

    And yes, when the MISO port detects an edge it write one byte out on...

    Ok,
    I figured out one mistake. I gave the offset in bit instead of byte. That probably crashed the CPU. Still the DMA doesn't seem to resond to the SPIs requests.
  8. Hardware triggered DMA data transfer setup problem

    Greetiungs fellow programmers.

    I encountered a problem, while trying to hook a DMA channel to an SPI DMA request on a Teensy 3.1 board. The program below is supposed to work in the following way:...
