FAQ:

Q. Do i need to make changes to firmware for STM32F405 ?
A. Nope. You no need to change anything.

Q. Can you provide photo of your MCU test board ?
A. Yes. As example you can use such boards.

Nice project. What lin driver did you install?

[moonglow]

@Memfispro Thank you! You can use TJA1021 as LIN bus driver.

@Memfispro Thank you! You can use TJA1021 as LIN bus driver.

Thank you.

has there been a daughter board designed to drop in place to attach to the MCUDEV DEVEbox board?

[moonglow]

@mitchdetailed Hi ! I just attach all modules by wires... Special boards is not very suitable for DIY...

Q1; is it theoretically possible to change pinout to match F407 discovery or would it hit any pin/DMA/etc conflicts?

Q2: any chance to have pinout flexible at build time with defines etc?

[moonglow]

A1: yep you can try absolutely any board you want with F407/F405 IC just connect pins as it described at main page table.
A2: nice tips, i will think about it.

Added support for HEX-V2 clone ( it will works as single channel CAN adapter, HW is STM32F415VG based ): LINK

Hi!
I have a STM32F405 board and want to flash this code.
I dont understand if need bootloadr or not.
I have to program the microcontroller with stlink and that's it?
should I use the bin or the hex?
I installed stm32cubeprogrammer, do you recommend something else?

thank you very much

@MC-tecnologias how much experience do you have with stm32 platform?

Please note that stm32 has build-in bootloader allowing you to program a chip using UART or CAN or USB.

hi @rusefillc !
thank you for replying.
I have experience in microcontrollers but mainly microchip family.
If I plug my board to the PC in DFU mode it recognizes it as "STM32 BOOTLOADER", so I could load the code that way?
should I choose the bin or the hex?

[rusefillc]

@MC-tecnologias i think you can load either of binary files

[MC-tecnologias]

I have my board programmed!
And windows recognize as "XCAN-USB-PRO CAN Device", but I dont have the driver installed.
Where can I download the driver?
