Damien George	a5d97f1db9	stm32: Add soft timer implementation, using SysTick at 1ms resolution. This commit adds an implementation of a "software timer" with a 1ms resolution, using SysTick. It allows unlimited number of concurrent timers (limited only by memory needed for each timer entry). They can be one-shot or periodic, and associated with a Python callback. There is a very small overhead added to the SysTick IRQ, which could be further optimised in the future, eg by patching SysTick_Handler code dynamically.	2019-10-31 22:12:55 +11:00
Damien George	1bcf4afb10	stm32/systick: Make periodic systick callbacks use a cyclic func table. Instead of checking each callback (currently storage and dma) explicitly for each SysTick IRQ, use a simple circular function table indexed by the lower bits of the millisecond tick counter. This allows callbacks to be easily enabled/disabled at runtime, and scales well to a large number of callbacks.	2019-02-08 01:20:13 +11:00

Damien George	01dd7804b8	ports: Make new ports/ sub-directory and move all ports there. This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.	2017-09-06 13:40:51 +10:00
