Posted on May 17, 2011 at 13:29Hi,
we are currently working on a CANopen stack for the STM32F103. Now we have some problems with a baudrate.
Everything works fine for 1Mbit, 800, 500, 250, 125, 50, 20 kBits but
10 kBits doen't work.
We uses a PCLK1 clock with 32 MHz.
Our parameter table for the baudrates looks like that:
Prescaler, total no of quantas, sampling point
{ 2 , 16,14 }, ///< 1000 kBit/s
{ 4 , 10, 8 }, ///< 800 kBit/s
{ 4 , 16,14 }, ///< 500 kBit/s
{ 8 , 16,14 }, ///< 250 kBit/s
{ 16 , 16,14 }, ///< 125 kBit/s
{ 40 , 16,14 }, ///< 50 kBit/s
{ 100 , 16,14 }, ///< 20 kBit/s
{ 200, 16,14 } ///< 10 kBit/s
SWJ is always 1qt.
The CAN Controller shows ''Bit dominant error'' and ''form error'' erros.
Has somebody a idea what the problem could be?

Joern
