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

61ef031687 stm32/uart: Move config of char_width/char_mask to uart.c. 2018-12-10 16:21:50 +11:00

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.

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.

7d7f59d78b stm32/uart: Factor out code to set RX buffer to function uart_set_rxbuf. 2018-12-10 16:21:50 +11:00

9690757cca stm32/uart: Rework uart_get_baudrate so it doesn't need a UART handle. 2018-12-10 16:21:50 +11:00

524e13b006 stm32/uart: Factor out code from machine_uart.c that computes baudrate. 2018-12-10 16:21:50 +11:00

9c6c32cc51 esp32/machine_pwm: On deinit stop routing PWM signal to the pin. 
Fixes issue #4273.

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.

9d3372bded stm32: Add peripheral support for STM32L432. 
The L432 does not have: GPIOD, TIM3, SPI2, ADC dual mode operation, 2-banks
flash.

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.

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

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.

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

c6365ffb92 stm32/powerctrl: Add support for standby mode on L4 MCUs. 
This maps to machine.deepsleep() which is now supported.

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.

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.

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.

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.

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.

80aca27a40 unix/modos: Rename unlink to remove to be consistent with other ports. 
We standardized to provide uos.remove() as a more obvious and user-friendly
name.  That's what written in the docs.  The Unix port implementation
predates this convention, so update it now.

as part of the usual "make" build process.

A board must be able to set the PLL3 values based on the HSE that it uses.

746dbf78d3 py/py.mk: When building axtls use -Wno-all to prevent all warnings. 
Building axtls gives a lot of warnings with -Wall enabled, and explicitly
disabling all of them cannot be done in a way compatible with gcc and
clang, and likely other compilers.  So just use -Wno-all to prevent all of
the extra warnings (in addition to the necessary -Wno-unused-parameter,
-Wno-uninitialized, -Wno-sign-compare and -Wno-old-style-definition).

Fixes issue #4182.

454cca6016 py/objmodule: Implement PEP 562's __getattr__ for modules. 
Configurable via MICROPY_MODULE_GETATTR, disabled by default.  Among other
things __getattr__ for modules can help to build lazy loading / code
unloading at runtime.

5a91fce9f8 py/objstr: Make str.count() method configurable. 
Configurable via MICROPY_PY_BUILTINS_STR_COUNT.  Default is enabled.
Disabled for bare-arm, minimal, unix-minimal and zephyr ports.  Disabling
it saves 408 bytes on x86.

For example, on Android, pthread functions are part of libc, so LIBPTHREAD
