On this 32-bit arch there's no need to use the long version of the format
specifier. It's only there to appease the compiler which checks the type
of the args passed to printf. Removing the "l" saves a bit of code space.
in recent circuitpython builds, `ubinascii` is available as
`binascii`. This modifies `modules/inisetup.py` to use the same
import semantics as `modules/websocket_helper.py`: first try importing
`ubinascii`, and if that fails, fall back to importing `binascii`.
Closesadafruit/circuitpython#795
This commit replaces the literal calls to `esptool.py` with the
`$(ESPTOOL)` Makefile variable. This allows one to set the esptool
invocation on the Make command line:
make ESPTOOL="python2 $(which esptool.py)"
(or via the environment, an include file, etc)
Closes#793
The order of function calls in an arithmetic expression is undefined and so
they must be written out as sequential statements.
Thanks to @dv-extrarius for reporting this issue, see issue #3690.
the py/makeversionhdr.py script was looking for `conf.py` in the
`docs/` directory, but this was relocated in 46e7f8e. This is used by
the fallback `get_version_info_from_docs_conf` method, which is only
consulted if `git` is unavailable in the build environment.
Closes#791.
If a socket is cleanly shut down by the peer then reads on this socket
should continue to return zero bytes. The lwIP socket API does not have
this behaviour (it only returns zero once, then blocks on subsequent calls)
so this patch adds explicit checks and logic for peer closed sockets.
Add --init to the submodule update example, thus, all submodules get
initialised including the nested (--recursive) ones. Without it there
might not be a submodule init.
Disabling this saves around 6000 bytes of code space and gets the 512k
build fitting in the available flash again (it increased lately due to an
increase in the size of the ESP8266 SDK).
In adcall.py the pyb module may not be imported, so use ADCAll directly.
In dac.py the DAC object now prints more info, so update .exp file.
In spi.py the SPI should be deinitialised upon exit, so the test can run a
second time correctly.
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART). Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority. This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.
For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.
This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).
The problem is the existing code which tries to optimise the
reinitialisation of the DMA breaks the abstraction of the HAL. For the
STM32L4 the HAL's DMA setup code maintains two private vars (ChannelIndex,
DmaBaseAddress) and updates a hardware register (CCR).
In HAL_DMA_Init(), the CCR is updated to set the direction of the DMA.
This is a problem because, when using the SD Card interface, the same DMA
channel is used in both directions, so the direction bit in the CCR must
follow that.
A quick and effective fix for the L4 is to simply call HAL_DMA_DeInit() and
HAL_DMA_Init() every time.
