Discounted price has again disappeared, I missed opportunity to purchase a second board ... :(
So, I will put my eggs on stm32duino OSHW board ... :)

Yes ! I've mentioned it in this post of the current thread : viewtopic.php?f=39&t=1162&start=40#p15038
The reason is that older PCB revision wasn't compatible to Arduino Mega but newer revision is.
The bad side of the new revision is that silkscreen is now only printed on bottom side, there is no more pinout silkscreen on top.

Hello

I Would like acces to Lot of USART ? I can't acces to UASRT 1 PB6 PB7 . Nothing pinOut . I'm working with Mbed Online Compiler .
Library Serial.h .. i need 3 UART or better.
Thank you for your Help !!!
Best regard ...

It is probably related to the fact that they change some pin layout for Mega compatibility as mentioned here :

Note : on newest board layout, the PB6/PDB7 are switched with the PD6/PD3 to get pins compatibility with Arduino Mega.

thank for you reply .
After lot test with mbed compile OnLine Serial.h:

Code: Select all

Serial Serial6( PB_6 , PB_7 )  = Serial Serial9( PA_9 , PA_10 );

Serial Serial8( PC_6 , PC_7 ) = Serial pc ( USBTX , USBRX );
There is only 2 USART .. :cry: :cry: :cry: :cry: :cry:

Have you get a idea for acces to lot of USART ??

Regard

As I am lately more involved in F4 stuff, I thought it's time to refresh this thread a bit...

Martin, do you still have a version where the SD card is working with our stm32duino? Can you maybe share the code or point out what exactly to do in order to get SPI working?
I managed to make Arduino to recognize the included external libraries in the sketches by reworking the repo include paths and header files.
USB serial and GPIOs work indeed on black F4 board.
Now I would like to see SD lib with SPI "in action", which is not yet working in my case (TXE bit is never detected to be set...).

From what I remember, it was the default code of stm32duino, without any special hacks.

EDIT : BTW, I almost never use SD lib, but using SdFat lib from Greiman.

Me too ;)

I'll try the SPI lib from your repo, maybe it will work.

Well, there are a lots of errors when compiling SPI.cpp...
Are you really sure that you tried the SD card with our (Roger's) stm32duino repo?
Do you maybe have your latest working version locally which you could share?
