This patch makes second and next calls to <socket>.close() a no-op.
It prevents GC from closing the underlying resource after user
already used <socket>.close() explicitly.
fixes#2355
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.
So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.
During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.
I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation. So we can now remove this unused typedef,
to simplify the mpconfigport.h file.
Fixing Issue #2243. Main problems were:
- HAL_ADC_GetState(adcHandle) may return other bits set (not only
HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
is done in two functions.
Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.
Thanks to mattbrejza for discovering the bug.
For example, the following code now works with a file on the SD card:
f = open('test', 'rb') # test must be 1024 bytes or more in size
f.seek(511)
f.read(513)
Also works for writing.
Fixes issue #1863.
