You don't need a voltage divider on the CAN_TX line because the signal is coming from the Teensy. What resistor value did you used ? Post a photo of the setup.
How did you check the pins on the Teensy 3.6 are still ok ? The CANH and CANL doesn't connect to the T3.6.
You can try and add a voltage divider from CAN_RX (CRX pin) to the T3.6 but damage might have already been...
The Teensy 3.6 is not 5v input tolerant. The way you have connected the MCP2551 to the 5v supply and the logic out to the T3.6 is 5v. You might have damaged the T3.6.
You also need a 120R terminator on each end of...
I see the 10.1" display has a dot pitch of 0.2175(W)x0.2088(H)mm. Do you have any problem drawing a circle ? Does it look round ?
I had loads of problems with non square pixels trying to draw circle and boxes.
You can use SMD connector like this one:

Soldering the connector on can be quite tricky.
If you want to connect the Teensy to the CAN-bus then you would need a transceiver IC.
There are many tutorials on Youtube.
Try this one:

You can also get 7" LCD with SPI but be careful with them. Some of them the pixel is not square. That means drawing circle does not look like a circle on screen. Square is not square !!
You can get 5" LCD with SPI.

There is a driver for Teensy by sumoty:

Thanks for the code mjs513.
It almost work. I can get a good image on the PC but on the LCD the image looks corrupted. I think some setting is not quite right.
I've got an ArduCAM Mini OV2640 working with Teensy 4.0 thanks to mjs513

It can connect to a PC host and capture images.
Is there any example code to drive...
I'm using a 5" RA8875 LCD with a Teensy 3.6.
The driver I'm using is the one from Sumotoy v0.70
I'm trying to display a bitmap image but it looks like something is corrupted.
I followed the conversion tutorial...
For CAN FD you need to use CRX3 and CTX4. That is the pins on the back side of the Teensy board.
CRX1/CTX1 or CRX2/CTX2 is CAN2.0B not FD.
You would need two 120R terminating resistors in your network.
You...
I would use a scope and check the 5v supply on the USB to the Teensy. Check if it drops below 5v when you energise the solenoid.
Also the depends on the size of the solenoid, your SSR might not be able to handle the...
