STM CircleOS forum / How to use CAN bus interface and USB interface at the same time?

mei · 2007-11-07 06:05:15

I checked the datasheet of STM32F10x, the CAN bus and USB bus shared one RAM, but if we want to use the USB and CAN at the same time, is there solution to deal with the shraed SRAM?

hello,
Since the USB and CAN peripherals share the same RAM memory for data reception and transmission, it’s not possible to run both of these two communications peripherals at the same time.

hello,
Thank you!
I feel very regret that this CPU can not be act as a gateway between CAN and USB.
even the size(pin number is not so much),performance, power consumption is very good.

Hope ST can update the CPU design in the future to remove the limit.
