Peter D. Gray 1f1623d3b7 stm32/usbdev: Be honest about data not being written to HID endpoint.
USB_HID.send() should now return 0 if it could not send the report to the
host.

This patch is only cosmetic and has no functional change.

Damien George aea71dbde0 stm32/Makefile: Use -O2 to optimise compilation of lib/libc/string0.c. 2018-05-04 15:53:51 +10:00
Damien George cb3456ddfe stm32: Don't use %lu or %lx for formatting, use just %u or %x.
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.

Damien George b614dc73b0 stm32/dma: Fix duplicate typedef of struct, it's typedef'd in dma.h. 2018-05-04 15:35:43 +10:00

Damien George 4fa7d36cee esp32: Use mp_rom_map_elem_t and MP_ROM_xxx macros for const dicts. 2018-05-02 22:33:41 +10:00
Damien George 6681eb809a esp32/modsocket: Correctly handle reading from a peer-closed socket.
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.

Torwag fb7dabb971 esp32/README: Add --init to submodule update command.
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.

Damien George 6410e174c5 esp8266: Disable DEBUG_PRINTERS for 512k build.
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).

Damien George 051686b0a8 stm32/main: Clean up and optimise initial start-up code of the MCU. 2018-05-02 15:20:24 +10:00
Damien George a03e6c1e05 stm32/irq: Define IRQ priorities directly as encoded hardware values.
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).

Peter D. Gray 266446624f stm32/dma: Always deinit/reinit DMA channels on L4 MCUs.
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.

Damien George a28bd4ac94 stm32/mphalport: Add mp_hal_pin_config_speed() to select GPIO speed.
It should be used after mp_hal_pin_config() or mp_hal_pin_config_alt().

iabdalkader 28c9824c51 stm32/boards/NUCLEO_H743ZI: Enable ADC peripheral. 2018-05-01 15:39:03 +10:00
iabdalkader 8c12f1d916 stm32/adc: Add support for H7 MCU series.
ADC3 is used because the H7's internal ADC channels are connected to ADC3
and the uPy driver doesn't support more than one ADC.

Only 12-bit resolution is supported because 12 is hard-coded and 14/16 bits
are not recommended on some ADC3 pins (see errata).

Values from internal ADC channels are known to give wrong values at
present.

Damien George 23e9c3bca7 esp32/modules: Add support scripts for WebREPL.
WebREPL now works on the esp32 in the same way it does on esp8266.

Damien George c1d4352e65 esp32/mpconfigport: Enable webrepl module and socket events. 2018-04-27 23:57:57 +10:00
Damien George 999c8b9711 esp32/modsocket: Add support for registering socket event callbacks.
The esp8266 uses modlwip.c for its usocket implementation, which allows to
easily support callbacks on socket events (like when a socket becomes ready
for reading).  This is not as easy to do for the esp32 which uses the
ESP-IDF-provided lwIP POSIX socket API.  Socket events are needed to get
WebREPL working, and this patch provides a way for such events to work by
explicitly polling registered sockets for readability, and then calling the
associated callback if the socket is readable.

Damien George 527ba0426c stm32/system_stm32: Reconfigure SysTick IRQ priority for L4 MCUs.
After calling HAL_SYSTICK_Config the SysTick IRQ priority is set to 15, the
lowest priority.  This commit reconfigures the IRQ priority to the desired
TICK_INT_PRIORITY value.
