This is a continuation of the earlier post, speeding up analogread() at the Arduino Zero. There are I2C environments where multiple masters are driving the bus. The origin O is generally selected at the center of gravity of ROV G. Set DCMI to JPEG mode ( without HSYNC VSYNC synchronization). Note:Software is allowed to set ADSTART only when ADEN=1 and ADDIS=0 (ADC is enabled and there is no pending request to disable the ADC) Anyway, I recommend setting up a timer triggered sequence and the DMA. The method preferred by the STM32 design is to configure the ADC to read two channels, using an enumerated list, to scan them in a non-continuous fashion, and be software triggered.
