Porting Serialisation to chip wihtout SWI interrupts

[GeorgD]

Faced with problem in subject during porting Serialisation to STM32F4 chip. Serialisation library extensively uses function call triggered by NVIC. How to substitute this functionality on other chip which lacks this feature?

I'm new to STM32 but have worked on exactly the same task recently. A workaround I came up with is to reuse EXTI interrupts and trigger them with NVIC_SetPendingIRQ calls. It might also be possible to define custom interrupts in the interrupt vector table, as the STM32F4 should support up to 256 interrupts.
