Paul Sokolovsky 2e75a17bab esp8266: Fix issue when current repl line was garbage-collected. 
Reference it from root pointers section.
 2016-03-30 18:13:03 +03:00
Paul Sokolovsky b1dfdaf6cb py/ringbuf.h: Add reusable ring buffer class. 
Features inline get/put operations for the highest performance. Locking
is not part of implementation, operation should be wrapped with locking
externally as needed.

Paul Sokolovsky f50d9477c1 docs: network: esp8266: .scan() is now synchronous and returns result list. 2016-03-30 11:56:20 +03:00
Paul Sokolovsky d7019d0628 docs: network: esp8266: status is WLAN object method. 2016-03-30 11:53:45 +03:00
Damien George 9475cc59e6 esp8266: Support synchronous wifi scanning. 
That is: aps = if0.scan()

TODO: make sure that returned list has tuple with values in "standard"
order (whatever that standard is).

Damien George 2599672384 py/parsenum: Use pow function to apply exponent to decimal number. 
Pow is already a dependency when compiling with floats, so may as well
use it here to reduce code size and speed up the conversion for most
cases.
 2016-03-29 22:12:07 +01:00
Damien George e1e7657277 py/formatfloat: Fix further cases of buffer overflow in formatting. 
Includes extensive test cases to catch hopefully all cases where
buffer might overflow.
 2016-03-29 22:07:15 +01:00
Damien George 03b8bb7ec9 py/formatfloat: Fix case of float format where leading digit was "10". 
When taking the logarithm of the float to determine the exponent, there
are some edge cases that finish the log loop too large.  Eg for an
input value of 1e32-epsilon, this is actually less than 1e32 from the
log-loop table and finishes as 10.0e31 when it should be 1.0e32.  It
is thus rendered as :e32 (: comes after 9 in ascii).

There was the same problem with numbers less than 1.

Paul Sokolovsky d88250c06e esp8266: Reduce heap size for now to avoid random segfaults on WiFi connect. 2016-03-29 21:14:41 +03:00
Paul Sokolovsky c4506ed869 esp8266: Let esp8266 "os" messages go to standard (REPL) UART. 
That's definitely helpful for debugging.
 2016-03-29 21:10:10 +03:00
Paul Sokolovsky 402a743821 esp8266/esp_mphal: Add support for debug UART-only output. 
Helpful when debugging dupterm support (because otherwise all output is
spooled to dupterm too).

To use:

mp_printf(&mp_debug_print, "...");

Damien George 6ca17c1922 esp8266: Implement os.urandom function. 
Uses what is suspected to be a hardware random number generator.
 2016-03-29 10:29:57 +03:00
Paul Sokolovsky b4070ee8a4 esp8266: Allow to build without FatFs support again. 2016-03-28 21:35:41 +03:00

danicampora 193795398d docs: Correct pin interrupt example code for the WiPy. 2016-03-28 13:12:58 +02:00
Damien George 71d40f132d esp8266: Zero out fs_user_mount state on (soft) reset. 
Otherwise device stays mounted on soft reset and leads to corruption
(since block device object is now gone).
 2016-03-28 13:28:41 +03:00
Paul Sokolovsky 9edd736ee6 esp8266/moduos: Add os.remove(), proxying to VFS object. 2016-03-28 12:50:07 +03:00
Paul Sokolovsky e8e116e7fc esp8266/moduos: Factor out VFS method proxy helper. 2016-03-28 12:44:36 +03:00
Paul Sokolovsky 8b08a0d9ed esp8266/moduos: Add listdir() proxy for MP_STATE_PORT(fs_user_mount)[0]. 
I.e. os.listdir(...) will redirect to
MP_STATE_PORT(fs_user_mount)[0].listdir(...).
 2016-03-28 12:29:47 +03:00
Damien George 61230e007d esp8266/moduos: Use mp_rom_map_elem_t for static const dictionary. 2016-03-28 12:08:36 +03:00
Paul Sokolovsky b01a373adb esp8266: deploy: Use --flash_size=8m option to esptool.py. 
Most esp8266 modules have at least 1MB (8Mbit) of flash. If not set, vendor
functions allow to access only first 512K.
 2016-03-28 11:28:16 +03:00
Paul Sokolovsky cd6194aefc esp8266/esp8266.ld: Put FatFs to FlashROM. 2016-03-27 17:15:25 +03:00

Paul Sokolovsky fd86bf5917 esp8266/modesp: flash_write(): Writes in multiples of 4 bytes. 2016-03-27 15:32:58 +03:00
Paul Sokolovsky 53302f1616 esp8266: Set up UART handling task soon into init process. 
Otherwise, events may be posted to non-initialized task, which leads to
segfaults.
 2016-03-27 14:33:17 +03:00
Paul Sokolovsky 651a188299 extmod/vfs_fat_diskio: Actually support sectors != 512 with Python blockdevs. 2016-03-27 14:21:06 +03:00
Paul Sokolovsky 13394a632d unix/unix_mphal: Hack to make uos.dupterm() actually work. 
See https://github.com/micropython/micropython/issues/1736 for the
list of complications. This workaround instead of duplicating REPL
to another stream, switches to it, because read(STDIN) we use otherwise
is blocking call, so it and custom REPL stream can't be used together.
 2016-03-27 14:02:03 +03:00

Paul Sokolovsky ba640bde55 esp8266/esppwm.c: Fix IRQ handler prototype. 2016-03-26 00:34:28 +02:00
Damien George 632d8efa05 esp8266: Add PWM support. 
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.
 2016-03-26 00:32:37 +02:00
Damien George 82b95f625e esp8266: Implement software SPI class. 
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins.  Only supports MSB output at the moment.

Paul Sokolovsky 91031a75a1 extmod/modlwip: lwip_socket_setsockopt: Handle option value properly. 2016-03-25 20:53:52 +02:00
Paul Sokolovsky 4332d72fd8 extmod/modlwip: Add lwip->POSIX error map for lwIP 1.4.0. 
Between 1.4.0 and 1.4.1, lwIP errors were renumbered.
 2016-03-25 20:32:01 +02:00
Paul Sokolovsky de0c84ebf1 extmod/modlwip: lwip_tcp_send: Handle properly send buffer full condition. 
Per POSIX http://pubs.opengroup.org/onlinepubs/9699919799/functions/send.html :
"If space is not available at the sending socket to hold the message to be
transmitted, and the socket file descriptor does not have O_NONBLOCK set,
send() shall block until space is available. If space is not available at the
sending socket to hold the message to be transmitted, and the socket file
descriptor does have O_NONBLOCK set, send() shall fail [with EAGAIN]."
