Mike Causer bc7822d8e9 drivers/display/ssd1306.py: Add support for 72x40 displays.
The 72x40 OLED requires selecting the internal IREF, as opposed to the
default external IREF.  This is an undocumented feature in the SSD1306
datasheet, but is present in the SSD1315 datasheet.  It's possible the
72x40 OLED is actually using the newer SSD1315 controller.  Sending the
IREF select command to SSD1306 displays has no effect on them, so it's
added to the init_display() instead of wrapping in an "if width = 72".

Also tested on a 128x64 OLED using the SSD1315 controller (smaller ribbon
cable) and the proposed change has no effect on the display, as the module
comes with the correct current limiting resistor.  Internal and external
IREF work the same.

Fixes issue #7281.

Damien George a1bc32d8a8 drivers/sdcard: Add sleep_ms(1) delay in SDCard.readinto sync loop.
So this driver works on faster MCUs (that run this loop fast) with older,
slower SD cards.

Damien George e43a74a4db drivers/memory/spiflash: Add MICROPY_HW_SPIFLASH_ENABLE_CACHE option.
This only needs to be enabled if a board uses FAT FS on external SPI flash.
When disabled (and using external SPI flash) 4k of RAM can be saved.

Jim Mussared ed14435a8e extmod/modbluetooth: Refactor stack/hci/driver/port bindings.
Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack.  This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.

stijn 40ad8f1666 all: Rename "sys" module to "usys".
This is consistent with the other 'micro' modules and allows implementing
additional features in Python via e.g. micropython-lib's sys.

Note this is a breaking change (not backwards compatible) for ports which
do not enable weak links, as "import sys" must now be replaced with
"import usys".

robert-hh 8680a74595 drivers/display/ssd1306.py: Change the SET_COM_PIN_CFG setting.
Making it more specific to use 0x02 for display with an aspect ratio > 2
(resolutions 96x16 and 128x32) and 0x12 for all other sizes as recommended
by @mcauser.  Tested with a 64x32 display which did not work before.

Andreas Motl fbfea3b440 drivers/onewire: Fix undefined variable errors.
On CPython, and with pylint, the variables MATCH_ROM and SEARCH_ROM are
undefined.  This code works in MicroPython because these variables are
constants and the MicroPython parser/compiler optimises them out.  But it
is not valid Python because they are technically undefined within the scope
they are used.

This commit makes the code valid Python code.  The const part is removed
completely because these constants are part of the public API and so cannot
be moved to the global scope (where they could still use the MicroPython
const optimisation).

Damien George 894c550c86 stm32: Refactor bluetooth stack/hci/driver bindings.

Also updated the naming to be more consistent (mp_bluetooth_hci_*).

Work done in collaboration with Jim Mussared aka @jimmo.

Peter Hinch d2f22ea953 drivers/nrf24l01: Change pipe addrs in test to match Arduino addrs.
These addresses were initially chosen to match the nRF24 Arduino library
examples but they are byte-reversed.  So change them to be on-air
compatible with the Arduino library.

Also, the data sheet for the nRF24 says that RX data pipes 1-5 must share
the same top 32-bits, and must differ only in the LSbyte.  The addresses
used here (while correct because they are on TX pipe and RX pipe 0) are
misleading in this sense, because it looks like they were chosen to share
the top 32-bits per the datasheet.

Andrew Leech 30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.

Mateusz Kijowski 1751f5ac7b drivers/sdcard: Do not release CS during the middle of read operations.
It seems that some cards do not tolerate releasing the card (by setting CS
high) after issuing CMD17 (and 18) and raising it again before reading
data. Somehow this causes the 0xfe data start marker not being read and
SDCard.readinto() is spinning forever (or until this byte is in the data).

This seems to fix weird behviour of SDCard.readblocks() returning different
data, also solved hanging os.mount() for my case with a 16GB Infineon card.

Damien George cc5a94044a drivers/memory/spiflash: Rename functions to indicate they use cache.
This patch renames the existing SPI flash API functions to reflect the fact
that the go through the cache:

    mp_spiflash_flush -> mp_spiflash_cache_flush
    mp_spiflash_read  -> mp_spiflash_cached_read
    mp_spiflash_write -> mp_spiflash_cached_write

Damien George 86fe73beb9 drivers/memory/spiflash: Move cache buffer to user-provided config.
This patch removes the global cache variables from the SPI flash driver and
now requires the user to provide the cache memory themselves, via the SPI
flash configuration struct.  This allows to either have a shared cache for
multiple SPI flash devices (by sharing a mp_spiflash_cache_t struct), or
have a single cache per device (or a mix of these options).

To configure the cache use:

    mp_spiflash_cache_t spi_bdev_cache;

    const mp_spiflash_config_t spiflash_config =
        // any bus options
        .cache = &spi_bdev_cache,
    };

Damien George bdc875e602 drivers/memory/spiflash: Fix bugs in and clean up read/write functions.
mp_spiflash_read had a bug in it where "dest" and "addr" were incremented
twice for a certain special case.  This was fixed, which then allowed the
function to be simplified to reduce code size.

mp_spiflash_write had a bug in it where "src" was not incremented correctly
for the case where the data to be written included the caching buffer as
well as some bytes after this buffer.  This was fixed and the resulting
code simplified.

Damien George a739b35a96 drivers/memory/spiflash: Change to use low-level SPI object not uPy one.
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h).  This allows the SPI-flash driver to
be used independently from the uPy runtime.

Damien George 58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

Damien George 4e48700f9a drivers/memory/spiflash: Add support for QSPI interface.

software or hardware, as long as the spiflash driver is passed the correct
configuration structure.
