machine.POWER_ON is renamed to machine.PWRON_RESET to match other
reset-cause constants that all end in _RESET. The cc3200 port keeps a
legacy definition of POWER_ON for backwards compatibility.
- Refers to the technique of instantiating an object for use in an ISR by
specifying it as a default argument.
- Footnote detailing the fact that interrupt handlers continue to be
executed at the REPL.
When dealing with a board which controls chip reset with UART's DTR/RTS,
we never see REASON_DEFAULT_RST (0), only REASON_EXT_SYS_RST (6). However,
trying a "raw" module with with just TXD/RXD UART connection, on power up
it has REASON_DEFAULT_RST as a reset reason.
According to the Arduino ESP8266 implementation the first argument to the
wifi scan callback is actually a bss_info pointer. This patch fixes the
iteration over this data so the first 2 entries are no longer skipped.
Fixes issue #2372.
Interrupts during neopixel_write causes timing problems and therefore
wrong light patterns. Switching off IRQs should help to keep the strict
timing schedule.
This new config option allows to control whether MicroPython uses its own
internal printf or not (if not, an external one should be linked in).
Accompanying this new option is the inclusion of lib/utils/printf.c in the
core list of source files, so that ports no longer need to include it
themselves.
Adds horizontal scrolling. Right now, I'm just leaving the margins
created by the scrolling as they were -- so they will repeat the
edge of the framebuf. This is fast, and the user can always fill
the margins themselves.
modpybhspi now does the needed multiplexing, calling out to modpybspi
(bitbanging SPI) for suitable peripheral ID's. modmachinespi (previous
multiplexer class) thus not needed and removed.
modpybhspi also updated to following standard SPI peripheral naming:
SPI0 is used for FlashROM and thus not supported so far. SPI1 is available
for users, and thus needs to be instantiated as:
spi = machine.SPI(1, ...)
There was a bug in `framebuf1_fill` function, that makes it leave a few
lines unfilled at the bottom if the height is not divisible by 8.
A similar bug is fixed in the scroll method.
Arguments of an unknown type cannot be skipped and continuing to parse a
format string after encountering an unknown format specifier leads to
undefined behaviour. This patch helps to find use of unsupported formats.
The idea is that all ports can use these helper methods and only need to
provide initialisation of the SPI bus, as well as a single transfer
function. The coding pattern follows the stream protocol and helper
methods.
