It also works with the following STM32L4 series.
- STM32L496
- STM32L4A6
I used this as a reference.
-
frame format
This example support Extended frame format: with 29 identifier bits. -
CAN port
In this example, you can select the CAN port.
STM32L496/4A6 has two CAN ports.
You can use only CAN1 or both CAN1 and CAN2, but you cannot use only CAN2.
These GPIOs can be used as CAN.
| CAN | RX | TX | |
|---|---|---|---|
| CAN1 | PA11 | PA12 | |
| CAN1 | PB8 | PB9 | |
| CAN1 | PD0 | PD1 | |
| CAN1 | PI9 | PH13 | Not supported |
| CAN2 | PB5 | PB6 | |
| CAN2 | PB12 | PB13 |
CAN1_RX mapped to PA11, CAN_TX mapped to PA12
CAN2_RX mapped to PB5 , CAN2_TX mapped to PB6
CANInit(CAN_1000KBPS, 0); // CAN_RX mapped to PA11, CAN_TX mapped to PA12
CAN1_RX mapped to PB8, CAN_TX mapped to PB9
CAN2_RX mapped to PB12, CAN_TX mapped to PB13
CANInit(CAN_1000KBPS, 2); // CAN_RX mapped to PB8, CAN_TX mapped to PB9
CAN1_RX mapped to PD0 , CAN1_TX mapped to PD1
CAN2_RX mapped to PB12, CAN2_TX mapped to PB13
CANInit(CAN_1000KBPS, 3); // CAN_RX mapped to PD0, CAN_TX mapped to PD1
