    Defragster, you have prompted a lot of new thoughts... I took out the delays as they are unnecessary and took out the disable statement. It seems the most logical problem would be the radio...

    I have never written to the buffer like this. Is it simply a matter of a .print of exactly 512 bytes? Is there a way to determine the size of the buffer contents? If so I could monitor that and...

    Interesting thought. I have also thought about writing the data to memory for a few minutes then stop and write to the SD card. I appreciate the help. Gary

    Re BEGIN and END I thought that would eliminate any conflicts. Re interrupts I think the RFM69 fires an interrupt whenever it receives a transmission which can be a problem if writing to the SD...

    Defragster, it is set up to run with either usb power or 12V through a 5V regulator. Re the disable, before I got the teensy with the SDIO SD I had conflicting issues between the SD and the RFM69,...

    Teensy 3.6 hangs after hours running

    I am sending temperature array data to teensy SD card along with gps data. It typically runs for 2-3 hours then hangs up, always after it prints out the array data and moves to the gps data. The...

    Eureka! In the night it occurred to me the baud rates were maybe not matched between TX and RX. When I used your Can0.SetBaudRate in the TX everything worked, interrupts, polling... I also re-read...

    I will check but I don't think there is one on either end. I will also get the right resistors... I just had 100 ohm.

    Thanks, Tony. I had not clued in on setting the alternate pins. I think you are right about a connection, or at least hardware problem. I rewired everything for the nth time and have measured all...

    Here is the code for the Teensy 3.2 which is driving an Maxim MCP2562 transceiver. The transceivers have a standby which I have grounded but not an enable. I thought callback or interrupt was...

    Thanks, Robin. I did try that example, also, with both Can0 and Can1 on two teensy 3.6 boards. I have a teensy 3.2 driving two MCP2562 transceivers to the teensy 3.6. The scope signal indicates...
  12. Modifications with IFCT library

    Robinhva1, will you please post the code you have working with the IFCT library? I assume you changed the #include statement to IFCT and renamed the buses. I am trying to send from a teensy 3.2 and...

    KurtE, this code looks much better and is the way I started but was not clear how it would work. It seems like if a gps signal is coming in, but not complete, it moves on to the radio and checks to...

    Thanks to both of you for the ideas. I just picked these up so have not tried your ideas yet but will report back as soon as I test. Re the Adafruit library I was pretty confident since it works...

    I am trying to record GPS using the Adafruit ultimate gps breakout at 10 Hz and two Adafruit rfm69 transmitters running at ~8 Hz. GPS and radios work separately and record to the builtin SD card so...

    It works.

    [QUOTE=defragster;132495]The example here : I:\arduino-1.8.1\hardware\teensy\avr\libraries\SD\examples\CardInfo should work with the only change needed to SDIO on T_3.6 listed in the code.
