Hi,
this week I tried to compile my code for STM32F303 which compiles earlier for STM32F103.
Sofar I used this in order to remap AFIO->MAPR |= AFIO_MAPR_CAN_REMAP_REMAP2 my CAN.

What is the correct way to do it so I can compile the code for both platforms?

What is the intended way to do remap with ...

Hi Giovanni,
I dont wanna use to much of your time but in case you have some left for me I would appreciate some help identifing the which has this i2c DMA problem.
My Processor STM32F103RBT has a Revision 1 printed on the chip.
In the Datasheet it is mentioned that a register contains the revision ...

Hi Giovanni,
what exactly is newer?
Newer revision or different series like STM32F4xx?
I got revision Z.
I see that there are “Z”, “Y” or “1” or “2” or “X”.
Not sure if Z is the oldest or the newest.

The PCA9548A needs a one byte read this seems to cause a irq loop when calling the write one byte.
So the sequence is
i2cMasterReceiveTimeout(current_i2c_drv ...

Hi Giovanni,
today I tried a cheap card I bought in the supermarket. The test dies in err = f_stat("0:chtest.txt", &filinfo);
with a hardfault. I could not find out yet why, once I leave the func get_fileinfo() in ff.c Line 1908 I am in the hardfault handler.
I modified the main a little bit so I ...

Hi Giovanni,
I tried the SD Test and the 256MB SD card does not work there either. This Card is a V1.1 SD and I am not sure if the code this really fully supports it right now.
I ordered a V2.0 SD since from my point of view it does not make sense to support this old stuff and I will continue with ...

Hi Giovanni,
thank you for the fast reply. Where can I get 3.0?
Thx.
