Any 180MHz STM32F4 series will work.
- STM32F427
- STM32F429
- STM32F437
- STM32F439
- STM32F446
- STM32F469
- STM32F479
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. -
CAN1 and CAN2
In this example, you can use CAN1 and CAN2 port.
STM32F446 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 |
| CAN2 | PB5 | PB6 |
| CAN2 | PB12 | PB13 |
STM32F427/429/437/439/469/479 has two CAN ports.
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 |
