    Simple DMA ISR Not Firing on Teensy 4.1

    Posting code seems to be removing content on final Serial.println. Should read: Serial.println(dst); Not sure why.

    Simple DMA ISR Not Firing on Teensy 4.1

    Sorry about that. See corrected code that compiles. / #include <Arduino.h> #include <imxrt.h> #include <DMAChannel.h> DMAChannel dma; DMAMEM uint32_t src[4] = { 10, 20, 30, 40 }; DMAMEM uint32_t dst[4]; volatile bool dmaDone = false; void dmaISR() { dma.clearInterrupt(); dmaDone =...

    Simple DMA ISR Not Firing on Teensy 4.1

    Hello, I can't seem to get a simple DMA transfer to work. Attached is the code I am trying to make work. I am running on a Teensy 4.1. Thanks for any help I can get. ------ #include <Arduino.h> #include <imxrt.h> #include <DMAChannel.h> DMAChannel dma; DMAMEM uint32_t src[4] = { 10, 20...

    GPIO_EMC Usage for A/D Output Data

    Hello, I want to connect an A/D (LTC2296) to the MIMXRT1062. From what I can tell, this can be accomplished using the GPIO_EMC pins. I am considering the following pin mappings. D0-D13 to GPIO_EMC_02-GPIO_EMC_15. CLKOUT to GPIO_EMC_16. OE to GPIO_EMC_17. DATA_SELECT to GPIO_EMC_18. This...

    Teensy Connections on GPIO_B0 Port

    Hello, I am needing to using the entire GPIO_B0 port to read some fast (20 Msps) data in (all 16 bits at a time). To do this, there are three I/Os on the Teensy board GPIO_B0_13, 14, and 15 that I need to move to another set of I/Os. How do I accomplish this? We have purchased the Teensy...

    Best Storage Option for MIMXRT1062

    Thanks for the reply. Our sample rate will be high, up to 10 Msps. We aim to read the external A/D (parallel data bits) and use DMA to transfer the data into memory. We will then utilize either Ethernet or USB to exfiltrate the data. Does this seem reasonable? What am I missing?

    Best Storage Option for MIMXRT1062

    Hello, We need to capture several MB of A/D data, and then access that data via algorithms in the MIMXRT1062. I was wondering what the best memory option would be for this application. From what I can tell, either SD or MMC would provide the densities we need, but having to move the data back...

    Teensy 4.1 and GD32E230

    I just got my Teensy 4.1 and noticed it has the GD32E230 processor instead of the MKL02Z32 shown in the schematic. Will this change how the board(s) function? We plan to purchase MKL02Z32 chips from you for a custom design we are working on. Thank you.
