* 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/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.
* esp8266: Move PHY mode constants from modesp to modnetwork.Paul Sokolovsky2016-04-01
|
* esp8266: Reset term_obj on reboot.Damien George2016-03-31
| | | | | Also, term_obj can be NULL if socket enables REPL duplication signalling before os.dupterm is called, so it should be checked.
* esp8266: Implement input part of dupterm handling.Paul Sokolovsky2016-03-31
| | | | | | | | The idea is following: underlying interrupt-driven or push-style data source signals that more data is available for dupterm processing via call to mp_hal_signal_dupterm_input(). This triggers a task which pumps data between actual dupterm object (which may perform additional processing on data from low-level data source) and input ring buffer.
* esp8266: Switch back to accumulating input data via ring buffer.Paul Sokolovsky2016-03-30
| | | | | | | | But now it's generic ring buffer implemented via ringbuf.h, and is intended for any type of input, including dupterm's, not just UART. The general process work like this: an interrupt-driven input source puts data into input_buf, and then signals new data available via call to mp_hal_signal_input().
* esp8266: Fix issue when current repl line was garbage-collected.Paul Sokolovsky2016-03-30
| | | | Reference it from root pointers section.
* esp8266: Support synchronous wifi scanning.Damien George2016-03-30
| | | | | | | That is: aps = if0.scan() TODO: make sure that returned list has tuple with values in "standard" order (whatever that standard is).
* esp8266: Reduce heap size for now to avoid random segfaults on WiFi connect.Paul Sokolovsky2016-03-29
|
* esp8266: Let esp8266 "os" messages go to standard (REPL) UART.Paul Sokolovsky2016-03-29
| | | | That's definitely helpful for debugging.
* esp8266/esp_mphal: Add support for debug UART-only output.Paul Sokolovsky2016-03-29
| | | | | | | | | Helpful when debugging dupterm support (because otherwise all output is spooled to dupterm too). To use: mp_printf(&mp_debug_print, "...");
* esp8266: Enable uos.dupterm() method.Paul Sokolovsky2016-03-29
|
* esp8266: Add basic support for duplicating REPL output.Paul Sokolovsky2016-03-29
|
* esp8266: Implement os.urandom function.Damien George2016-03-29
| | | | Uses what is suspected to be a hardware random number generator.
* esp8266: Allow to build without FatFs support again.Paul Sokolovsky2016-03-28
|
* esp8266: Support importing modules from filesystem.Paul Sokolovsky2016-03-28
