USB-CAN

Overview

The prototype verification has been completed, and communication between the two modules is fine.
The current known issue is that the transmit/receive indicator lights are not lit.

After soldering, you can find the firmware yourself,
or visit CANable's website https://canable.io/ to use their website for web-based upgrade programming.
After verifying everything is working correctly, press and hold BOOT0 while plugging the device into the computer, or after plugging it into the computer, press and hold boot0 and then press RST to enter the bootloader.
Open CANable's programming page https://canable.io/updater/canable1.html. Select the firmware you want to program from the dropdown menu and click Connect and Update.

If the connection is correct and the driver is installed on your computer, the pop-up window will show STM32 BOOTLOADER. Select it and click Connect. Wait for the progress bar to complete; the programming is finished.

After programming, unplug and replug the USB cable, install the corresponding driver and host computer software, and then test the connection.
