Can CAN slave acknowledge CAN master message and vice versa?

A CAN device when sending a message needs an external device to acknowledge the message for successfull transmission. A device will not acknowledge its own message. What about CAN master and slave in a single e.g. the STM32F303? Can the slave acknowl...

Variables in domain D2 are not initialized ... here's why

By default, the variables in the D2 domain (SRAM1, SRAM2 and SRAM3) are not initialized by the linker because DATA_IN_D2_SRAM is not defined in the file system_stm32h7xx.c.DATA_IN_D2_SRAM is used by SystemInit () which is called by the STM32H7xx_Star...
