m-ecry 73493b909a STM-can-api: Fixed variable name for H7 
- can_frequency uses f instead of hz for can frequency
 - Also added comment to system_clock
 2020-09-16 17:35:32 +02:00
m-ecry d0c8ad75e1 STM-can-api: Support reading of remote_msg 
- Previously a received msg was fixed of data_type
 2020-09-14 18:10:48 +02:00
m-ecry 13b663397f STM-can-api: Added usage of prescaler 
- This enables more frequencies, but without regard to the accuracy.
May still require manual clock setup, to remain in tolerance window

Martin Eckardt 35c9e7a5ad Use HAL function for FDCAN_CLK-calculation 
- Thanks to @jeromecoutant for showing the HAL funtion
 - Added #ifdef guard to FDCAN2/3 handler functions

Martin Eckardt 08ce2f2de8 Calculate FDCAN_clk instead of assuming fix 10MHz 
- The FDCAN_clk is calculated on runtime from the according
RCC-registers

Added error checking to can_filter() for Classic CAN 
Previously the function always returned 1 even when the configuration was illegal. I added a small check to HAL_CAN_ConfigFilter(...).

Alexandre Bourdiol affe7113ef TARGET_STM: Remove timeout on HSEM. 
With tickless mechanism hsem can be used for quite a long time
(time to set up PLL clock).
Also, if hsem is held to long, then this is not the current core which is faulty,
but probably the other (the one which hold the HSEM)
 2019-11-27 14:25:43 +01:00
Alexandre Bourdiol adcf0e2fa5 DISCO_H747I Dualcore support 
Add 2 targets for DISCO_H747I dualcore:
* DISCO_H747I      -> for CM7 core
* DISCO_H747I_CM4  -> for CM4 core

Current restrictions:
* TICKLESS deactivated
* DeepSleep not supported (DeepSleep wrapped to sleep)

Warning: use of the same IP (example I2C1) by both core at the same time is not prevented,
but is strongly not recommended.
Some Hardware Semaphore are use for common IP, to manage concurrent access by both cores: Flash, GPIO, RCC.

Warning: Drag and drop of binary to DISCO_H747I will flash CM7.
         In order to flash CM4, one can use STM32 CubeProgrammer tool.

STM32: Fix CAN3
 2017-12-12 17:39:41 +00:00
Adam Heinrich 9ee222a8e6 STM32: Set valid filter number for CAN3 
Filter numbers 14 to 27 are reserved for dual CAN configuration.
However, CAN3 operates in single CAN configuration according to the
reference manual).

bcostm bfc4d68ae0 STM32 CAN3: remove test of CAN_2 and CAN_3 
CAN_2 and CAN_3 are enum and not #define and this causes compilation error with GCC_ARM

Instead put back the test of CAN_NUM (which are defined in can_device.h).

Laurent MEUNIER 04ac65a4e6 STM32: CAN: restore registers after can_reset 
After reset the MCR register content needs to be restored so we're
introducing the can_registers_init function to be called at the first
init stage, but also after reset. We also store the can frequency to
go through the initialisation phase again.
 2017-09-05 10:27:21 +02:00
Laurent MEUNIER 8357f6fe77 STM32: CAN: store the mode in object context 
In order to apply the same mode in case of reset, we store the current
requested mode in the HAL structure.

To make storage in a single place, we also change can_monitor to call
can_mode function as they actually acting on same registers.

Laurent MEUNIER 57222b604f STM32: CAN: do not overwite BTR register when setting frequency 
BTR register has other bits than the ones calculated and set through
the can_speed function, so let's take care to only write to the
right registers.
 2017-09-05 10:27:21 +02:00
Laurent MEUNIER 759642af8e STM32: Define CAN handle as part of can object 
Instead of a static object, this will make driver
instantiation more robust and allow to re-use init
configuration on a need basis.

The CANName struct member is actually the CAN registers base address,
which is now available in the CanHandle.Instance field, so we don't need
CANName anymore.
