 That was an idea of mine which i do work but it will not be a "product"  as the discovery board is
too big for normal applications and most important i am not "in the business", i just ride along for the fun.
I can't see how you can fit this combo to a quadcopter or a small airplane, it is very big and clumsy...
In any case a prototyping perforated board will do the job, the only things missing for normal operation are a few resistor dividers for the adc inputs, some pins for the servos and some holes for mounting.

Hi Marius,

I tried a bit with the stm32f4 discovery board and saw some code i don't understand:
I'm working with kronaks excel sheet (



B 9 does not support SPI1 NSS, i think A 4 would be correct.

You can use any gpio pin as SlaveSelect output, as that is handled by the paparazzi driver via spi_enable_software_slave_management of libopencm3.


# default flash mode is via usb dfu bootloader
# possibilities: DFU, SWD

Is there a dfu bootloader ? I havent found one anywhere yet. If not, i would change this to stlink as default.

The STM32F4 already has a DFU bootloader integrated.
You can use the dfu_util to flash it (and this is what is used by default for this board if you press upload in the paparazzi center).
Holding BOOT0 high and BOOT1=PB2 low during reset, and keeping the USART and CAN lines quiescent, should bring up a DFU bootloader on the USB micro-AB port.
Tanks, didn't know that, havent done anything with arm MCU yet ^^
I first thought SWD will work best, so i wrote the wiki artice.
I would start to write a article in the wiki, would be nice if i can get the status of the "sensor addon board".
Can i add it directly to stm32f4 based board ? ( I would add it with the sensor board as "one" board)
Which sensor addon board do you mean?

"A pcb companion for the stm32f4 discovery with all the needed hardware....
Anyway i think i can make a better companion-sensor pcb based on my flying experience :-)"
So i thoug he is working on something.

Cheers, Felix
