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. stmhal: L4: Modify adc.c to add support for STM32L4 series. 2016-04-16T22:02:36+00:00 Tobias Badertscher python@baerospace.ch 2016-03-22T10:28:35+00:00 urn:sha1:d49a5470640d29ce9ee7f2ebedbf9f2fcd8cc524 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*. 2016-01-11T00:49:27+00:00 Damien George damien.p.george@gmail.com 2016-01-03T15:55:55+00:00 urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t. all: Add py/mphal.h and use it in all ports. 2015-10-31T16:14:30+00:00 Damien George damien.p.george@gmail.com 2015-10-30T23:03:58+00:00 urn:sha1:731f359292c0e2630873df1a19c5baac7287024f py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations. stmhal: Factor GPIO clock enable logic into mp_hal_gpio_clock_enable. 2015-08-02T23:14:48+00:00 Damien George damien.p.george@gmail.com 2015-08-02T23:05:16+00:00 urn:sha1:0851751615580d02bd6f841e13651923f05fde59 Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable and called from anyplace which might need to use GPIO functions on ports other than A-D.
