Implementation of CAN communication between Hercules Safety MCUs - TMS570LS1224 and TMS570LS1227 & TM4C123GH6PM. Interrupts were employed on each node to notify successful transmission and reception of messages on the CAN network.
-
The Loop-back folder was used during debugging to check if the CAN module of each NODE was functional - this helped in eliminating the nodes as source of errors in the CAN network.
-
Initial Setup of CAN network: Blue = VCU - TMS570LS1227; RED = BMS - TMS570LS1224;
-
Issues: VCU's on-board tranceiver & BMS external transceiver were not able to translate bits from TTL to CAN bus logic.
- Improved Setup: Used external transceivers for both VCU and BMS:
- Tested same code with two TMS570LS1224s:
