    Made some progress… changing those SPI statements and, crucially, also providing better power to both CC1101 and screen (ie. not via the Teensy), I was able to get both working at the same time! But only briefly - I...

    Thanks guys. Just to recap, I have had both the display and the CC1101 working in their own, it's just when I try to get them working together that things stop working. And my coding skills are really quite basic, so...

    I'm pretty sure that both devices are SPI only, but I like the idea of putting them on a different SPI buses if that's possible - I'm not sure how to do that, however. Had a quick before but couldn't work it out… maybe...

    Ah, thanks. For now I'm still trying to make things work with the 4.0 board, though I've ordered a 4.1 to play about with also. I have followed Pilot's suggestion of trying to keep elements separate, but so far no...

    I'm also wondering whether maybe it's worth trying a Teensy 4.1 instead - if I understand correctly, the Micro SD card slot would simplify things, and I think there are hardware pins for two entirely separate SPI...

    Are there 3 SPI buses? Maybe SPI, SPI1 and SPI2? If I can't get this to work, I might try using an Arduino Pro Micro to handle the CC1101, and then have it send data to the Teensy via the RX/TX pins

    Just to clarify on sensors: to prolong their battery life, they normally only send data in short bursts every 60-90 seconds, when they're in a rotating tyre. Also when they detect a sudden drop in pressure. No movement...

    I'm sure the CC1101 stuff in isolation is OK - I think you're quite right about all that detail, but I had it working solidly with a different display (which didn't use the SPI bus), and also working with this wiring...

    ps. and, yes, it's VERY likely that problems are happening because I'm not sure how to adapt the code for both to work together!

    Thanks, that gives me some ideas to work with. Language-wise, like so much of the inconsistency or bad design here, it's because I've cut and pasted, and changed as little as I could get away with in order not to...

    OK, let me add some more detail about what I'm trying to sort outÖ I have all the key parts of the project working separately, and have made everything (decoding TPMS, sensor inputs, output to display) work together...

    Also,I have tried to use both the display and cc1101 on the main SPI bus, with one using pin 10 for CS and the other pin 27, but so far I canít get them working at the same time. Will post more details if I donít make...

    Thanks again! How could I modify this to make it work ono the SPI1 bus instead of the main SPI bus? As per previous post, I used this to get a test interface working with my screen but after trying to roll the RF...

    Thanks! I'd never have got this far without this thread ;-) I've started on the next steps, but I'm having trouble getting both the CC1101 and the screen working with the Teensy at the same time. I now have sketches...

    To clarify - the area bounded by the holes in the middle would be removed, to allow for the components on the underside of the Teensy 4

    Just tried that solution for the card reader, and I think it's pushing my soldering skills just a little too far, though I may try again with different wire. I'd planned on using a DIY breakout board like this...

    It's working! Thanks dude - yup, just made those changes in the library code and connected as specified, and I have the 'Hello world' example sketch working, so I know the Teensy is talking to the screen properly. ...

    Quick update: I think I've solved that problem… I had installed the wrong version of the SdFat library. No compilation errors now I don't have the screen working yet though, which maybe has to do with pin...
