STM32F103C6_CAN2

Firmware to test the CAN-BUS operation with CANALL_V2 STM32F103C8 based boards

Project overview

Project-targets

• Free Tool chain
• Use no HAL libraries
• Initialise everything directly to register level
• Traffic to CAN-BUS only when event happens
• No HOST, only nodes
• canALL_V2 boards connected on CAN-BUS network

Toolchain

• Atollic TrueSTUDIO®/STM32 Lite, Built on Eclipse, Version: 2.0.1 Lite, Build id: 20110128-1032

Functionality details

• Send to CAN only when an input is changed
• All Receiving boards transmit to UART, so CAN-BUS can be monitored on PC Terminal Emulator

Board

Setup

Atollic IDE

---

Atollic IDE was free when this project was created

---

Teraterm Serial Port Setup

---

Baud 115200, 8bit, No Parity, 1 Stop bit

---

Teraterm Terminal Setup

---

Adjust line width to 165 chars, to contail a single transaction message

---

Teraterm responce

---

One terminal line displays a CAN transaction

---

CAN and UART signals

---

At any input change:

• change is transmitted to CAN
• Overall STATUS of the board is transmitted to UART Osilloscope:
• Blue Channel is CAN-BUS
• Purple Channel is UART-TX

---

Custom ST-Link and UART adapter

connects:

• ST-LINK to board
• UART to RS232 level translator board and then to PC serial port
