suspect-devices/circuitpython/stmhal/systick.c, branch 5.3.0CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=5.3.02017-09-06T03:40:51+00:00ports: Make new ports/ sub-directory and move all ports there.2017-09-06T03:40:51+00:00Damien Georgedamien.p.george@gmail.com2017-09-06T03:40:51+00:00urn:sha1:01dd7804b87d60b2deab16712eccb3b97351a9b7
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.
all: Use the name MicroPython consistently in comments2017-07-31T08:35:40+00:00Alexander Steffendevel.20.webmeister@spamgourmet.com2017-06-30T07:22:17+00:00urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e
There were several different spellings of MicroPython present in comments,
when there should be only one.
stmhal/systick: Make mp_hal_delay_ms release the GIL when sleeping.2017-03-22T01:54:43+00:00Damien Georgedamien.p.george@gmail.com2017-03-22T01:54:43+00:00urn:sha1:3509e2d3074486e426b41aa89c6e01d591eb01adstmhal: Enable micropython.schedule().2017-03-20T04:20:26+00:00Damien Georgedamien.p.george@gmail.com2017-02-15T12:04:53+00:00urn:sha1:a5159edc2090a5670c33a829d7e54ab2ba8635c4
ExtInt, Timer and CAN IRQ callbacks are made to work with the scheduler.
They are still hard IRQs by default, but one can now call
micropython.schedule within the hard IRQ to schedule a soft callback.
stmhal: Rename sys_tick ticks/delay functions to corresp. mp_hal ones.2017-03-02T04:32:32+00:00Damien Georgedamien.p.george@gmail.com2017-03-02T04:32:32+00:00urn:sha1:89738e8240b0ae6dcc24c48d8e9e5078da90e15a
The renames are:
HAL_Delay -> mp_hal_delay_ms
sys_tick_udelay -> mp_hal_delay_us
sys_tick_get_microseconds -> mp_hal_ticks_us
And mp_hal_ticks_ms is added to provide the full set of timing functions.
Also, a separate HAL_Delay function is added which differs slightly from
mp_hal_delay_ms and is intended for use only by the ST HAL functions.
stmhal: Implement a proper thread scheduler.2017-02-15T02:28:48+00:00Damien Georgedamien.p.george@gmail.com2017-02-06T04:13:30+00:00urn:sha1:05a4859585c4e0a55fca2e7467ba70da6453fdcb
This patch changes the threading implementation from simple round-robin
with busy waits on mutexs, to proper scheduling whereby threads that are
waiting on a mutex are only scheduled when the mutex becomes available.
stmhal: Replace #include "stm32f4xx_hal.h" with #include STM32_HAL_H.2015-07-29T23:38:25+00:00Dave Hylandsdhylands@gmail.com2015-07-28T15:36:26+00:00urn:sha1:ea8bf8105812b36fbf1596a78c6e14aa0a0c5a36stmhal: Prefix includes with py/; remove need for -I../py.2015-01-01T21:06:20+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T21:06:20+00:00urn:sha1:2cf6dfa280a8149941aafc852fbaae8bdfc4999estmhal: Make pyb.[u]delay use systick with IRQs, busy loop otherwise.2014-11-30T21:23:25+00:00Damien Georgedamien.p.george@gmail.com2014-11-30T21:23:25+00:00urn:sha1:1960475ed7e190bcf537f8f7714a543b7513e2d5
pyb.delay and pyb.udelay now use systick if IRQs are enabled, otherwise
they use a busy loop. Thus they work correctly when IRQs are disabled.
The busy loop is computed from the current CPU frequency, so works no
matter the CPU frequency.
stmhal: Improve efficiency of SysTick IRQ and HAL_Delay.2014-08-25T17:12:44+00:00Damien Georgedamien.p.george@gmail.com2014-08-25T17:12:44+00:00urn:sha1:34e43c7ee9700249dc6e5b333b7c264d45d6b530
SysTick IRQ now increases millisecond counter directly (ie without
calling HAL_IncTick). Provide our own version of HAL_Delay that does a
wfi while waiting. This more than halves power consumption when running
a loop containing a pyb.delay call. It used to be like this, but new
version of HAL library regressed this feature.
