* esp8266: Add PWM support.Damien George2016-03-26
| | | | | | | | | | | | | | | | | PWM implementation uses a timer and interrupts (FRC1), taken from Espressif's/NodeMCU's implementation and adapted for our use. 8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15. Usage: import machine pwm0 = machine.PWM(machine.Pin(0)) pwm0.freq(1000) pwm0.duty(500) Frequency is shared (ie the same) for all channels. Frequency is between 1 and 1000. Duty is between 0 and 1023.
* esp8266: Implement software SPI class.Damien George2016-03-25
| | | | | Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any pins. Only supports MSB output at the moment.

|
* esp8266/ets_alt_task: Make FIRST_PRIO=0 to cover all task priorities.Damien George2016-03-17
| | | | | FIRST_PRIO=2 works but using 0 is hopefully safer, and can anyway be optimised in the future.
* esp8266: Store frozen modules in FlashROM.Paul Sokolovsky2016-03-17
| | | | Requires special lexer to access their contents.
* esp8266: Switch to lwIP built from source.Paul Sokolovsky2016-03-12
| | | | Using https://github.com/pfalcon/esp-open-lwip project.
* esp8266: Mention git submodule in build instructions for esp8266 port.Christopher Arndt2016-03-11
|
* esp8266: Rejig Makefile so extmod/modlwip.o is placed under build/.Damien George2016-03-11
|
* esp8266: Define MICROPY_EVENT_POLL_HOOK for the port.Paul Sokolovsky2016-03-11
|
* esp8266: Be sure to build ets_alt_task.Paul Sokolovsky2016-03-11
|
* esp8266/esp_mphal: Add higher-level event polling function.Paul Sokolovsky2016-03-11
| | | | ets_event_poll() polls both system events and uPy pending exception.
* esp8266/ets_alt_task: Update for vendor SDK 1.5.0.Paul Sokolovsky2016-03-11
| | | | | SDK 1.5.0 has a task with priority 3: ets_task(401001f4, 3, 3fff9808, 4). Recognizing SDK version requires the latets esp-open-sdk build.
* esp8266/ets_alt_task: Be sure to "pop" event before calling its handler.Paul Sokolovsky2016-03-11
| | | | | Otherwise, if handler calls recursive event loop, there's infinite recursion (because the loop calls the same handler on same event again).
* esp8266: Feed WDT in ets_loop_iter().Damien George2016-03-11
|
* esp8266: Add alternative event loop implementation.Paul Sokolovsky2016-03-11
| | | | | | | | | | | | | | This implementation provides the same interface and uses the same datastructures as used by BootROM, i.e. is a drop-in replacement for it. But it offers one advantage: it allows to run single iteration of event-pumping loop. Original BootROM function are renamed, prefixed with underscore. There's a switch which allows to use forward calls to them, for compatibility testing. The implementation also includes workarounds for hardware timer handler, and these workarounds may be SDK version specific.
* esp8266/modnetwork: Add symbolic names for network interfaces: STA_IF & AP_IF.Paul Sokolovsky2016-03-10
| | | | | These are expected to be passed to network.WLAN() to instantiate network interface objects.
* esp8266/modnetwork: Introduce interface .config() method.Paul Sokolovsky2016-03-10
| | | | | | | | | | | | Allows to set (in case keyword args are given) or query (in case a single "symbolic keyword" (a string, value is the same as keyword)) arbitrary interface paramters (i.e. extensible and adaptable to various hardware). Example usage: ap_if = network.WLAN(1) ap_if.config(essid="MicroPython on Air") print(ap_if.config("essid"))
* esp8266/modnetwork: Move config defines to the top.Paul Sokolovsky2016-03-10
|
* esp8266/modnetwork: Add per-interface .active() method.Paul Sokolovsky2016-03-10
| | | | | | Allows to up/down interface when called with a boolean, or query current state if called without args. This per-interface method is intended to supersede adhoc network.wifi_mode() function.
* esp8266: Move wifi_mode() and phy_mode() to network module.Paul Sokolovsky2016-03-10
|
* esp8266/modnetwork: Allow to configure STA and AP interfaces separately.Paul Sokolovsky2016-03-10
| | | | | | | | | On ESP8266, there're 2 different interfaces. Pretending it's not the case desn't make sense. So, network.WLAN() now takes interface id, and returns interface object. Individual operations are then methods of interface object. Some operations require i/f of specific type (e.g. .connect() makes sense only for STA), other are defined for any (e.g. .ifconfig(), .mac()).
* esp8266: Move pyb.freq to machine.freq.Damien George2016-03-09
|
* esp8266/main: Module to run on boot is "boot", not "main".Paul Sokolovsky2016-03-08
|
* esp8266: Put more code in iROM section.Damien George2016-03-08
| | | | | Also explicitly name the py/*.o files in the linker file, to enable easy testing of putting certain ones in iRAM.
* esp8266/Makefile: Add define for ESP8266 lwIP.Paul Sokolovsky2016-03-08
|
* esp8266: Enable modlwip.Damien George2016-03-08
|
* esp8266: Don't gc-collect BSS.Paul Sokolovsky2016-03-08
| | | | | | None of the other ports do, since introduction of mp_state_ctx_t. In the case of current esp8266 port, heap is inside BSS, so scanning it picked up a lot of dead pointers.
* esp8266: Enable stack overflow checking.Paul Sokolovsky2016-03-07
