It also works with the following STM32L4 series.
- STM32L432
- STM32L433
- STM32L452
- STM32L476
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.
STM32L432 has one CAN ports.
These GPIOs can be used as CAN.
| CAN | RX | TX |
|---|---|---|
| CAN1 | PA11 | PA12 |
STM32L433/476 has one CAN ports.
These GPIOs can be used as CAN.
| CAN | RX | TX | |
|---|---|---|---|
| CAN1 | PA11 | PA12 | |
| CAN1 | PB8 | PB9 | |
| CAN1 | PD0 | PD1 | Not supported |
STM32L452 has one CAN ports.
These GPIOs can be used as CAN.
| CAN | RX | TX | |
|---|---|---|---|
| CAN1 | PA11 | PA12 | |
| CAN1 | PB5 | PB6 | |
| CAN1 | PB8 | PB9 | |
| CAN1 | PB12 | PB13 | |
| CAN1 | PD0 | PD1 | Not supported |
