Nico Tonnhofer	efd8279c1a	STM32F411: implement DMA for ADC Eureka!!! The STM32 has only one data register for all channels. So I want to use the ADC over DMA. Issues are: It is not possible to stop the DMA or the ADC without uninit and init the hole parts. We have more or less one option. Manually start the ADC. So what we have now. We start the ADC after reading the values from DMA buffer. The ADC now make a conversion of all channels. We can read also the values because it uses a double buffer mode. With that mode we can read the unused buffer.	2017-03-03 18:54:57 +01:00
Nico Tonnhofer	4cb6f85e3c	STM32F411: implement analog-stm32.c It's not that easy like LPC. We need later an DMA to control all ADCs, because there is only one register to read the ADC.	2017-03-03 18:54:57 +01:00

STM32F411: implement analog-stm32.c

It's not that easy like LPC. We need later an DMA to control all ADCs, because there is only one register to read the ADC.
