Damien George 025d419a77 teensy: Add own uart.h to not rely on stm32's version of the file. 2018-12-10 23:55:11 +11:00
Damien George dc23978dde stm32/uart: Add ability to have a static built-in UART object.
A static UART is useful for internal peripherals that require a UART and
need to persist outside the soft-reset loop.
2018-12-10 16:21:50 +11:00
Damien George 61ef031687 stm32/uart: Move config of char_width/char_mask to uart.c. 2018-12-10 16:21:50 +11:00
Damien George 6ea45277bf stm32/uart: For UART init, pass in params directly, not via HAL struct.
To provide a cleaner and more abstract C-level interface to the UART.
2018-12-10 16:21:50 +11:00
Damien George e0c2432503 stm32/uart: Simplify deinit of UART, no need to call HAL.
The HAL just clears UE and then clears all the UART control registers.
2018-12-10 16:21:50 +11:00
Damien George bc3f0dddac stm32/uart: Remove HAL's UART_HandleTypeDef from UART object struct.
This UART_HandleTypeDef is quite large (around 70 bytes in RAM needed for
each UART object) and is not needed: instead the state of the peripheral
held in its registers provides all the required information.

Damien George 7d7f59d78b stm32/uart: Factor out code to set RX buffer to function uart_set_rxbuf. 2018-12-10 16:21:50 +11:00
Damien George 9690757cca stm32/uart: Rework uart_get_baudrate so it doesn't need a UART handle. 2018-12-10 16:21:50 +11:00
Damien George 524e13b006 stm32/uart: Factor out code from machine_uart.c that computes baudrate. 2018-12-10 16:21:50 +11:00
Damien George a2271532be stm32: Split out UART Python bindings from uart.c to machine_uart.c. 2018-12-10 16:21:50 +11:00
Damien George 55830dd9bf py/objexcept: Make sure mp_obj_new_exception_msg doesn't copy/format msg
mp_obj_new_exception_msg() assumes that the message passed to it is in ROM
and so can use its data directly to create the string object for the
argument of the exception, saving RAM.  At the same time, this approach
also makes sure that there is no attempt to format the message with printf,
which could lead to faults if the message contained % characters.

Fixes issue #3004.

Damien George bad4e15da5 py/objexcept: Use macros to make offsets in emergency exc buf clearer. 2018-12-10 15:53:38 +11:00
Paul Sokolovsky 38151f35c1 extmod/moductypes: Add aliases for native C types.
SHORT, INT, LONG, LONGLONG, and unsigned (U*) variants are being defined.
This is done at compile using GCC-style predefined macros like
__SIZEOF_INT__.  If the compiler doesn't have such defines, no such types
will be defined.

Damien George 074597f172 tests/extmod/uctypes_error: Add test for unsupported unary op. 2018-12-10 14:29:41 +11:00
Paul Sokolovsky 0de6815ec1 tests/extmod/uctypes_ptr_le: Test int() operation on a pointer field. 2018-12-10 14:25:06 +11:00
Paul Sokolovsky 9d864bde04 extmod/moductypes: Implement __int__ for PTR.
Allows to get address a pointer contains, as an integer.
2018-12-10 14:25:05 +11:00
Paul Sokolovsky d690c2e148 tests/basics/special_methods: Add testcases for __int__. 2018-12-07 17:28:04 +11:00
Paul Sokolovsky b1d08726ee py/obj: Add support for __int__ special method.
Based on the discussion, this special method is available unconditionally,
as converting to int is a common operation.
2018-12-07 17:28:04 +11:00
Damien George 113f00a9ab py/objboundmeth: Support loading generic attrs from the method.
Instead of assuming that the method is a bytecode object, and only
supporting load of __name__, make the operation generic by delegating the
load to the method object itself.  Saves a bit of code size and fixes the
case of attempting to load __name__ on a native method, see issue #4028.

Damien George da7355e213 esp32/modmachine: Enable machine.sleep() now that the IDF supports it. 2018-12-06 17:23:27 +11:00
Damien George 9c6c32cc51 esp32/machine_pwm: On deinit stop routing PWM signal to the pin.
Fixes issue #4273.
2018-12-06 17:05:16 +11:00
Damien George 287b02d98a esp32/machine_pwm: Support higher PWM freq by auto-scaling timer res. 2018-12-06 16:43:39 +11:00
Damien George 87623082e3 esp32/machine_uart: Implement UART.sendbreak() method.
The uart_write_bytes_with_break() function requires non-zero data to be
sent before the break, so a standalone break must be synthesised.

boochow 69b7b8fa12 stm32/boards: Add NUCLEO_L432KC board configuration files. 2018-12-06 13:33:29 +11:00
boochow 9d3372bded stm32: Add peripheral support for STM32L432.
The L432 does not have: GPIOD, TIM3, SPI2, ADC dual mode operation, 2-banks
flash.
2018-12-06 13:32:43 +11:00
boochow 1a8baad7ca stm32/boards: Add STM32L432KC chip configuration files.
The pin alternate function information is derived from ST's datasheet
https://www.st.com/resource/en/datasheet/stm32l432kc.pdf
In the datasheet, the line 2 of AF4 includes I2C2 but actually the chip
does not have I2C2 so it is removed.

Damien George 52bec93755 esp8266/machine_uart: Add rxbuf keyword arg to UART constructor/init.
As per the machine.UART documentation, this is used to set the length of
the UART RX buffer.
2018-12-05 23:31:24 +11:00
Damien George 9ddc182ec7 esp32/machine_uart: Add txbuf/rxbuf keyword args to UART construct/init.
As per the machine.UART documentation, these are used to set the length of
the TX and RX buffers.
2018-12-05 16:48:34 +11:00
Damien George 8007d0bd16 stm32/uart: Add rxbuf keyword arg to UART constructor and init method.
As per the machine.UART documentation, this is used to set the length of
the RX buffer.  The legacy read_buf_len argument is retained for backwards
compatibility, with rxbuf overriding it if provided.
2018-12-05 13:24:11 +11:00
Damien George c6365ffb92 stm32/powerctrl: Add support for standby mode on L4 MCUs.
This maps to machine.deepsleep() which is now supported.

Damien George eed522d69f stm32/mboot: Add support for 4th board LED. 2018-12-04 23:14:30 +11:00
Damien George 13e92e1225 stm32/mboot: Provide led_state_all function to reduce code size. 2018-12-04 23:11:51 +11:00
Damien George 9262f54138 stm32/uart: Always show the flow setting when printing a UART object.
Also change the order of printing of flow so it is after stop (so bits,
parity, stop are one after the other), and reduce code size by using
mp_print_str instead of mp_printf where possible.

See issue #1981.

Damien George da1d849ad1 stm32,esp8266,cc3200: Use MICROPY_GC_STACK_ENTRY_TYPE to save some RAM. 2018-12-04 18:32:10 +11:00
Ayke van Laethem 31cf528c75 py: Add option to reduce GC stack integer size to save RAM.
A new option MICROPY_GC_STACK_ENTRY_TYPE is added to select a custom type
instead of size_t for the gc_stack array items.  This can be beneficial for
small devices, especially those that are low on memory anyway.  If a device
has 1MB or less of heap (and 16-byte GC blocks) then this type can be
uint16_t, saving 128 bytes of RAM.

Damien George 62b4bebf64 esp8266/modnetwork: Wait for iface to go down before forcing power mgmt.
If the STA interface is connected to an AP then it must be fully
disconnected and deactivated before forcing the power management on.

Craig Younkins 7f948a5645 py/py.mk: Fix broken Gmane URL. 2018-12-04 01:03:44 +11:00
Damien George 29da9f0670 extmod/modlwip: Fix read-polling of listening socket with a backlog.
The recent implementation of the listen backlog meant that the logic to
test for readability of such a socket changed, and this commit updates the
logic to work again.
2018-12-03 18:02:10 +11:00
roland 10bddc5c28 stm32/boards/STM32F429DISC: Enable UART as secondary REPL.
The board(s) feature a VCOM through the ST-LINK, this feature is something
to keep around.
2018-12-01 17:30:48 +11:00
Damien George 4737ff8054 extmod/modlwip: Implement TCP listen/accept backlog.
Array to hold waiting connections is in-place if backlog=1, else is a
dynamically allocated array.  Incoming connections are processed FIFO
style to maintain fairness.

Damien George 9e2dd93145 esp8266/ets_alt_task: Process idle callback if no other events occurred. 2018-12-01 17:20:05 +11:00
Damien George 485514f57a esp32: Allocate task TCB and stack from system heap not uPy heap.
This is necessary for two reasons: 1) FreeRTOS still needs the TCB data
structure even after vPortCleanUpTCB has been called, so this latter hook
function cannot free the TCB, and there is no where else to safely delete
it (this behaviour has changed recently in the ESP IDF); 2) when using
external SPI RAM the uPy heap is in this external memory but the task stack
must be allocated from internal SRAM.

Fixes issue #3904.
2018-11-28 15:00:45 +11:00
Damien George 0233049b79 esp32/mpthreadport: Prevent deadlocks when deleting all threads.
vTaskDelete now immediately calls vPortCleanUpTCB, which requires the
thread_mutex mutex, so vTaskDelete must be called after this mutex is
released.
