2023-06-08py/builtinimport: Remove weak links.Jim Mussared
In order to keep "import umodule" working, the existing mechanism is replaced with a simple fallback to drop the "u". This makes importing of built-ins no longer touch the filesystem, which makes a typical built-in import take ~0.15ms rather than 3-5ms. (Weak links were added in c14a81662c1df812c0c6b4299f97966302f16477) This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
2023-06-06samd/boards: Rename flash pins consistently for QSPI and SPI.robert-hh
For SAMD21 devices, the board flash signals must be named in pins.csv as FLASH_MOSI, FLASH_MISO, FLASH_SCK, FLASH_CS for creating the SPI object. And rename the QSPI pins to QSPI_xxxx instead of FLASH_xxx. Signed-off-by: robert-hh <robert@hammelrath.com>

2023-05-23samd/machine_uart: Add support for UART hardware flow control.robert-hh
By specifying rts=pin(x) and/or cts=Pin(x) in the constructor. The pad numbers for the UART pins are fix in this case: TX must be at pad 0, RX at pad 1, RTS at pad 2 and CTS at pad 3. repr(uart) shows the pin names for rts and cts, if set. In case of a RX overflow, the rx interrupt will be disabled instead of just discarding the data. That allows RTS to act. If RTS is inactive, still 2 bytes can be buffered in the FIFO.

2023-05-22tools/mpremote: Add repl option to escape non-printable characters.Damien George
This commit adds the "--escape-non-printable" option to the repl command. When specified the REPL console will escape non-printable characters, printing them as their hex value in square brackets. This escaping behaviour was previously the default and only behaviour, but it is now opt-in. As part of this change, the speed of echoing device data to the console is improved by by reading and writing in chunks. Signed-off-by: Damien George <damien@micropython.org>

2023-05-18rp2: Make rp2_state_machine_exec accept integers.Adam Green
Currently rp2.StateMachine.exec(instr_in) requires that the instr_in parameter be a string representing the PIO assembly language instruction to be encoded by rp2.asm_pio_encode(). This commit allows the parameter to also be of integral type. This is useful if the exec() method is being called often where the use of pre-encoded machine code is desireable. This commit still supports calls like: sm.exec("set(0, 1)") It also now supports calls like: # Performed once earlier, maybe in __init__() assembled_instr = rp2.asm_pio_encode("out(y, 8)", 0) # Performed multiple times later as the PIO state machine is # configured for its next run. sm.exec(assembled_instr) The existing examples/rp2/pio_exec.py and examples/rp2/pio_pwm.py that exercise the rp2.StateMachine.exec() method still work with this change.

2023-05-06esp32,esp8266: Add support to set/get power saving mode of WLAN.glenn20
For esp32 and esp8266 this commit adds: - a 'pm' option to WLAN.config() to set/get the wifi power saving mode; and - PM_NONE, PM_PERFORMANCE and PM_POWERSAVE constants to the WLAN class. This API should be general enough to use with all WLAN drivers. Documentation is also added.

2023-05-04docs: Update the PWM examples based on recent API improvements.robert-hh
This adds the freq and duty_u16 keyword settings to the constructor, and sometimes other details in the PWM section. For mimxrt a clarification regarding the PWM invert argument was added, and for rp2 a few words were spent on PWM output pairs of a channel/slice.
2023-05-04samd/machine_pwm: Add init() method to PWM and simplify the PWM code.robert-hh
The PWM.init() method has been added. Calling init() without arguments restarts a PWM channel stopped with deinit(). Otherwise single parameters except for "device=n" can be changed again. The device can only be specified once, either in the constructor or the first init() call. Also simplify get_pwm_config() and get_adc_config(), and shrink the PWM object.

2023-05-01esp32,esp8266: Add support for the Espressif ESP-NOW protocol.Glenn Moloney
ESP-NOW is a proprietary wireless communication protocol which supports connectionless communication between ESP32 and ESP8266 devices, using vendor specific WiFi frames. This commit adds support for this protocol through a new `espnow` module. This commit builds on original work done by @nickzoic, @shawwwn and with contributions from @zoland. Features include: - Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO. - Signal strength (RSSI) monitoring. - Core support in `_espnow` C module, extended by `espnow.py` module. - Asyncio support via `aioespnow.py` module (separate to this commit). - Docs provided at `docs/library/espnow.rst`. Methods available in espnow.ESPNow class are: - active(True/False) - config(): set rx buffer size, read timeout and tx rate - recv()/irecv()/recvinto() to read incoming messages from peers - send() to send messages to peer devices - any() to test if a message is ready to read - irq() to set callback for received messages - stats() returns transfer stats: (tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts) - add_peer(mac, ...) registers a peer before sending messages - get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt) - mod_peer(mac, ...) changes peer info parameters - get_peers() returns all peer info tuples - peers_table supports RSSI signal monitoring for received messages: {peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...} ESP8266 is a pared down version of the ESP32 ESPNow support due to code size restrictions and differences in the low-level API. See docs for details. Also included is a test suite in tests/multi_espnow. This tests basic espnow data transfer, multiple transfers, various message sizes, encrypted messages (pmk and lmk), and asyncio support. Initial work is from https://github.com/micropython/micropython/pull/4115. Initial import of code is from: https://github.com/nickzoic/micropython/tree/espnow-4115.

2023-04-26extmod/btstack: Include value handle in client read/write events.Jim Mussared
This replaces the previous pending operation queue (that used to also be shared with pending server notify/indicate ops) with a single pending operation per connection. This allows the value handle to be correctly passed to the Python-level events. Also re-structure GATT client event handling to simplify the packet handler functions.

2023-04-26extmod/modbluetooth: Merge gatts_notify/indicate implementation.Jim Mussared
Makes gatts_notify and gatts_indicate work in the same way: by default they send the DB value, but you can manually override the payload. In other words, makes gatts_indicate work the same as gatts_notify. Note: This removes support for queuing notifications and indications on btstack when the ACL buffer is full. This functionality will be reimplemented in a future commit. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
2023-04-21rp2/machine_i2c: Add timeout parameter for machine.I2C().David (Pololu)
This commit adds support for the `timeout` keyword argument to machine.I2C on the rp2 port, following how it's done on other ports. The main motivation here is avoid the interpreter crashing due to infinite loops when SDA is stuck low, which is quite common if the board gets reset while reading from an I2C device. A default timeout of 50ms is chosen because it's consistent with: - Commit a707fe50b085ec83722106609f6fd219faf9f030 which used a timeout of 50,000us for zero-length writes on the rp2 port. - The machine.SoftI2C class which uses 50,000us as the default timeout. - The stm32 port's hardware I2C, which uses 50,000us for I2C_POLL_DEFAULT_TIMEOUT_US. This commit also fixes the default timeout on the esp32 port to be consistent with the above, and updates the documentation for machine.I2C to document this keyword argument.
2023-03-09rp2/modrp2: Disable other core, shorten delay to 8us in bootsel_button.David Grayson
This function seems to work fine in multi-core applications now. The delay is now in units of microseconds instead of depending on the clock speed, and is adjustable by board configuration headers. Also added documentation.

2023-02-21samd/mcu: Implement a hardware seed for the SAMD21 random module.robert-hh
By using the phase jitter between the DFLL48M clock and the FDPLL96M clock. Even if both use the same reference source, they have a different jitter. SysTick is driven by FDPLL96M, the us counter by DFLL48M. As a random source, the us counter is read out on every SysTick and the value is used to accumulate a simple multiply, add and xor register. According to tests it creates about 30 bit random bit-flips per second. That mechanism will pass quite a few RNG tests, has a suitable frequency distribution and serves better than just the time after boot to seed the PRNG.

2022-12-08py: Pass in address to compiled module instead of returning it.Damien George
This change makes it so the compiler and persistent code loader take a mp_compiled_module_t* as their last argument, instead of returning this struct. This eliminates a duplicate context variable for all callers of these functions (because the context is now stored in the mp_compiled_module_t by the caller), and also eliminates any confusion about which context to use after the mp_compile_to_raw_code or mp_raw_code_load function returns (because there is now only one context, that stored in mp_compiled_module_t.context).

2022-11-25tools/mpremote: Only auto connect to serial device with USB VID/PID.Michael Mogenson
On MacOS and Windows there are a few default serial devices that are returned by `serial.tools.list_ports.comports()`. For example on MacOS: ``` {'description': 'n/a', 'device': '/dev/cu.Bluetooth-Incoming-Port', 'hwid': 'n/a', 'interface': None, 'location': None, 'manufacturer': None, 'name': 'cu.Bluetooth-Incoming-Port', 'pid': None, 'product': None, 'serial_number': None, 'vid': None} {'description': 'n/a', 'device': '/dev/cu.wlan-debug', 'hwid': 'n/a', 'interface': None, 'location': None, 'manufacturer': None, 'name': 'cu.wlan-debug', 'pid': None, 'product': None, 'serial_number': None, 'vid': None} ``` Users of mpremote most likely do not want to connect to these ports. It would be desirable if mpremote did not select this ports when using the auto connect behavior. These serial ports do not have USB VID or PID values and serial ports for Micropython boards with FTDI/serial-to-USB adapter or native USB CDC/ACM support do. Check for the presence of a USB VID / PID int value when selecting a serial port to auto connect to. All serial ports will still be listed by the `list` command and can still be selected by name when connecting. Signed-off-by: Michael Mogenson <michael.mogenson@gmail.com>
