You can now create (singleton) objects representing the flash and SD
card, using:
flash = pyb.Flash()
sdcard = pyb.SDCard()
These objects provide the block protocol.
Adds a lot of code, makes IRQs a bit less efficient, but is very useful
for debugging. Usage: pyb.irq_stats() returns a memory view that can be
read and written, eg:
list(pyb.irq_stats())
pyb.irq_stats()[0]
pyb.irq_stats()[0] = 0
The patch provides general IRQ_ENTER() and IRQ_EXIT() macros that can be
modified to provide further IRQ statistics if desired.
To let unix port implement "machine" functionality on Python level, and
keep consistent naming in other ports (baremetal ports will use magic
module "symlinking" to still load it on "import machine").
Fixes#1701.
This makes select.poll() interface fully compatible with CpYthon. Also, make
their numeric values of these options compatible with Linux (and by extension,
with iBCS2 standard, which jopefully means compatibility with other Unices too).
Fetch the current usb mode and return a string representation when
pyb.usb_mode() is called with no args. The possible string values are interned
as qstr's. None will be returned if an incorrect mode is set.
This patch overhauls the network driver interface. A generic NIC must
provide a set of C-level functions to implement low-level socket control
(eg socket, bind, connect, send, recv). Doing this, the network and
usocket modules can then use such a NIC to implement proper socket
control at the Python level.
This patch also updates the CC3K and WIZNET5K drivers to conform to the
new interface, and fixes some bugs in the drivers. They now work
reasonably well.
This is experimental support. API is subject to changes. RTS/CTS
available on UART(2) and UART(3) only. Use as:
uart = pyb.UART(2, 9600, flow=pyb.UART.RTS | pyb.UART.CTS)
UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.
Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.
The object includes optional read buffering, using interrupts. You can set
the buffer size dynamically using read_buf_len keyword arg. A size of 0
disables buffering.
os, time, select modules are now prefixed with u, but are still
available (via weak links) as their original names.
ure and ujson now available as re and json via weak links.
This patch enables output on the complimentary channels (TIMx_CHyN).
For timers 1 and 8, deadtime can also be inserted when the channels
transition. For the pyboard, TIM8_CH1/CH1N and TIM8_CH2/CH2N can
take advantage of this.
Timers now have the following new features:
- can init freq using floating point; eg tim.init(freq=0.1)
- tim.source_freq() added to get freq of timer clock source
- tim.freq() added to get/set freq
- print(tim) now prints freq
As per issue #876, the network module is used to configure NICs
(hardware modules) and configure routing. The usocket module is
supposed to implement the normal Python socket module and selects the
underlying NIC using routing logic.
Right now the routing logic is brain dead: first-initialised,
first-used. And the routing table is just a list of registered NICs.
cc3k and wiznet5k work, but not at the same time due to C name clashes
(to be fixed).
Note that the usocket module has alias socket, so that one can import
socket and it works as normal. But you can also override socket with
your own module, using usocket at the backend.
Pulled in and modified work done by mux/iabdalkader on cc3k driver, from
iabdalkader-cc3k-update branch. That branch was terribly messy and had
too many conflicts to merge neatly.
Fix stmhal and teensy print routines to report actual prescaler an period.
Fix teensy build to use soft-float
Add USE_ARDUINO_TOOLCHAIN option to teensy build
This allows to set the pulse width (for PWM mode) as a ratio relative to
the period of the timer. Eg, 0.5 is a 50% duty cycle. You can set the
ratio in the channel init, or using channel.pulse_width_ratio; the
latter can also read the pulse width as a ratio.
