* esp8266/qstrdefsport.h: Mark qstr's for "esp" module.Paul Sokolovsky2016-04-15
|
* esp8266: Enable input() builtin.Paul Sokolovsky2016-04-15
|
* py: Declare help, input, open builtins in core.Paul Sokolovsky2016-04-15
| | | | These are *defined* per-port, but why redeclare them again and again.
* esp8266/scripts/port_diag.py: Module to collect diagnostic info.Paul Sokolovsky2016-04-14
| | | | | A shortcut for users to provide background diagnostic info for bug reports.
* esp8266: Switch integer arith routines to BootROM.Paul Sokolovsky2016-04-14
|
* esp8266: Separate 1-wire timing funcs from Python module to save iRAM.Damien George2016-04-14
| | | | | esponewire.c contains low-level timing-critical functions that go in iRAM. modonewire.c contains Python wrapper code.
* esp8266: Add hard IRQ callbacks for pin change on GPIO0-15.Damien George2016-04-14
|
* esp8266: Add dummy entries for non-existing pins to simplify pin logic.Damien George2016-04-14
| | | | | Now pins can be easily looked up in the table using the pin number as the index and vice versa.
* esp8266: Remove pin_id field from C pin object.Damien George2016-04-14
| | | | This field is the same as phys_port and not needed.
* py: Add ability to have frozen persistent bytecode from .mpy files.Damien George2016-04-13
| | | | | | | The config variable MICROPY_MODULE_FROZEN is now made of two separate parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This allows to have none, either or both of frozen strings and frozen mpy files (aka frozen bytecode).
* esp8266/esp_mphal: call_dupterm_read(): Fix order of deactivating on EOF.Paul Sokolovsky2016-04-13
| | | | First deactivate, then print diagnostic message.
* esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write().Paul Sokolovsky2016-04-13
| | | | | | | The idea is that if dupterm object can handle exceptions, it will handle them itself. Otherwise, object state can be compromised and it's better to terminate dupterm session. For example, disconnected socket will keep throwing exceptions and dump messages about that.
* lib/utils/printf: Rework overriding printer of DEBUG_printf().Paul Sokolovsky2016-04-13
| | | | | By default it uses mp_plat_print, but a port may override it to another value with MICROPY_DEBUG_PRINTER_DEST.
* esp8266: In callback helpers, pop nlr_buf on successful call.Damien George2016-04-13
| | | | | | | nlr_pop must be called if no exception was raised. Also, return value of these callback helpers is made void because ther is (currently) no use for it.
* esp8266: Enable framebuf module.Damien George2016-04-12
|
* esp8266: Switch from using custom I2C driver to generic extmod one.Damien George2016-04-12
|
* esp8266: Implement basic C-level pin HAL.Damien George2016-04-12
|
* esp8266: Protect modpyb.h header file from multiple inclusions.Damien George2016-04-12
| | | | Also include py/obj.h so the header is self contained.
* esp8266/scripts/inisetup.py: Use "-" in AP ESSID instead of space.Damien George2016-04-12
|
* esp8266/scripts/inisetup.py: Set WPA/WPA2 AP mode with a predefined password.Paul Sokolovsky2016-04-12
|
* esp8266: Add Python modules for initial configuration.Paul Sokolovsky2016-04-12
| | | | | | | | | Main entry point is _boot.py which checks whether FAT FS in flash mountable, and if so, mounts it. Otherwise, it checks if flash is empty, and if so, performs initial module setup: makes FAT FS, configures default AP name, etc. As a last option, if flash is not empty, and could not be mounted, it means filesystem corruption, and warning message with instructions is printed in an infinite loop.
* esp8266/scripts/main.py: Remove stale file.Paul Sokolovsky2016-04-12
|
* esp8266/modnetwork: .config(): Add "password" param (W/O).Paul Sokolovsky2016-04-12
|
* esp8266/modnetwork: .config(): Add "authmode" param.Paul Sokolovsky2016-04-12
|
* esp8266/modnetwork: .config(): Check interface whose config is requested.Paul Sokolovsky2016-04-12
|
* esp8266: Enable websocket module.Paul Sokolovsky2016-04-11
|
* esp8266/modesp: Add freemem() and meminfo() functions.Paul Sokolovsky2016-04-11
| | | | | They call into vendor SDK functions system_get_free_heap_size() and system_print_meminfo() respectively.
* esp8266/main: mp_builtin_open(): Implement, using vfs_proxy_call().Paul Sokolovsky2016-04-10
|
* esp8266: Implement multistage bootstrap sequence.Damien George2016-04-10
| | | | | | | | | | | | | Upon start-up, _boot module is executed from frozen files to do early initialization, e.g. create and mount the flash filesystem. Then "boot.py" is executed if it exists in the filesystem. Finally, "main.py" is executed if exists to allow start-on-boot user applications. This allows a user to make a custom boot file or startup application without recompiling the firmware, while letting to do early initialization in Python code. Based on RFC https://github.com/micropython/micropython/issues/1955.
* esp8266: Switch from terse error messages to normal ones.Damien George2016-04-07
| | | | Adds 2k to the code size.
* esp8266/README: Add short troubleshooting section.Paul Sokolovsky2016-04-07
|
* esp8266: Add initial implementation of machine.UART.Damien George2016-04-06
| | | | Currently UART(0) and UART(1) are exposed and only uart.write works.
* esp8266: Make destination for vendor OS debug output soft-configurable.Damien George2016-04-06
| | | | | Use esp.osdebug(None) to disable, or esp.osdebug(uart_id) to send output to a UART.
* esp8266/modnetwork: require_if(): Report the actual interface required.Paul Sokolovsky2016-04-05
|
* esp8266: Move pyb.unique_id() to machine.unique_id().Paul Sokolovsky2016-04-05
|
* esp8266: Move pyb.hard_reset() to machine.reset().Paul Sokolovsky2016-04-05
|
* esp8266: Bump heap size to 24k.Paul Sokolovsky2016-04-03
|
* esp8266: Update flashing instructions in README.Paul Sokolovsky2016-04-03
|
* esp8266: Switch back to flashing combined firmware (single file).Paul Sokolovsky2016-04-03
| | | | | With gap between segments minimized, there's not much padding to flash, so no big speed overhead.
* esp8266: Minimize gap between Inst/DataRAM segments and FlashROM segment.Paul Sokolovsky2016-04-03
| | | | | | | | | With .rodata being in FlashROM now, gap can be much smaller now. InstRAM can be max 32K, and with segment headers, that already makes it more than 32K. Then there's some .data still, and the next Flash page boundary is 0x9000. That figure should be more or less future-proof. TODO: Refactor makeimg to take FlashROM segment offset from file name.
* esp8266/ets_alt_task: Comment out debug output.Paul Sokolovsky2016-04-03
|
* esp8266: Bump iROM size to 512k.Paul Sokolovsky2016-04-03
| | | | Needed for frozen scripts, and for future growth of binary.
* esp8266: Move .rodata where it belongs with -mforce-l32 help.Paul Sokolovsky2016-04-03
|
* esp8266/README: Add link to docs.Paul Sokolovsky2016-04-03
|
* esp8266: Use VM_HOOK to call ets_loop_iter within the VM.Damien George2016-04-02
| | | | Starting with a divisor of 10, pystone_lowmem gives a score of 256.
* esp8266/uart: Get ctrl-C working now that event-based REPL is disabled.Damien George2016-04-01
|
* esp8266/uart: Comment out old, unused rx buffering code.Damien George2016-04-01
| | | | | | | This was originally used for non-event based REPL processing. Then it was unused when event-based processing was activated. But now that event based is disabled, and non-event based is back, there has been new ring buffer code to process the chars.
* esp8266: Switch to non event-driven REPL to support paste mode.Paul Sokolovsky2016-04-01
|
* esp8266: Support dedicated REPL loop (aka pull-style).Paul Sokolovsky2016-04-01
| | | | | | | | Event-driven loop (push-style) is still supported and default (controlled by MICROPY_REPL_EVENT_DRIVEN setting, as expected). Dedicated loop worked even without adding ets_loop_iter(), though that needs to be revisited later.
* esp8266: Disallow recursive calls to REPL.Paul Sokolovsky2016-04-01
| | | | | | | | | Before this change, if REPL blocked executing some code, it was possible to still input new statememts and excuting them, all leading to weird, and portentially dangerous interaction. TODO: Current implementation may have issues processing input accumulated while REPL was blocked.
