CAN adapter CAN protocol and GPIO control working simultaneously

vtguru

Hardware:  
1. A: Ginkgo USB-CAN Bus Adapter [size=12.8013px]VTG202A
2. B: Ginkgo USB-CAN Interface VTG203B
3. C: CAN driver module (comes with VTG202A)
4. D: pull up resistor (using one I2C EEPROM module instead)

Connection:
Ginkgo I2C/SPI/CAN pin layout:


PIN NUMBER      connection
2:  3.3V output to CAN driver module;
10: connect to CAN driver module RX;
12: connect to CAN driver module TX;
14: GPIO5, using I2C EEPROM module pull up resistor only;
19,20: GND  


Software

If need two can modules connected to Ginkgo CAN adapter, the connection will be:
   can module 1   Adapter (pinout)
   VCC:               P2: 3.3V
   GND:              P20: gnd
   RX:                 P10 (CAN1_RX)
   TX:                 P12 (CAN1_TX）

   can module 2   Adapter (pinout)
   VCC:                P2: 3.3V
   GND:               P19: gnd
   RX:                  P4 (CAN2_RX)
   TX:                  P6 (CAN2_TX）
