Beskrivning
This project aims to investigate and develop a way to expand testing capabilities on CAN based testing environments. The company has suggested a solution using a microcontroller together with a CAN shield allowing to connect to the CAN bus. Then using in house-built test-cards for controlling I/O or relays. Both the CAN shield, and the test-cards will communicate over SPI. The test-cards should be able to be stacked to increase the number of outputs or to run distributed over multiple microcontrollers on the CAN bus. The requirements for the system aren’t final but a time requirement for setting signals has been decided to be 10ms. To achieve this, I will investigate the impact of having one or multiple SPI channels on the microcontroller and using filters on the CAN bus. For a fully completed project the PCB design for the test-cards should be developed and a human-machine-interaction layer should be added.
