    PEAK-System programmable hardware products. For each supported product, examples are included. On delivery the PCAN-RS-232 converter is supplied with the example firmware 6_CAN_TO_SER_BY_COMMAND that routes from CAN to RS-232 and vice versa. It allows to configure the data transfer as well as the hardware with serial control commands.
  • Page 17 Creating your own firmware: 1. Create a folder on your computer. We recommend using a local drive. 2. Unzip the development package PEAK-DevPack.zip completely into the folder. No installation is required. 3. Run the script SetPath_for_VSCode.vbs. This script will modify the example directories for the Visual Studio Code IDE.
