For ADC slave, ADC is enabled only (conversion is not started). The injected mode is a mode where the ADC conversion can be "injected" during the conversion of regular channels due to some trigger (timer or something else). -Continuous Conversion is enabled. Has anyone got an example of how to trigger an ADC from a Timer, and, then use the DMA to transfer the results from the ADC to a buffer in RAM. · Regular and Injected conversions. STM32 F4 - ADC in Dual Mode Simultaneously. Dual 12Bit DAC. The Scan mode is selected by setting the SCAN bit in the ADC_CR1 register. Injected Conversion Mode: None. The ADC embedded in STM32 microcontrollers uses the SAR (successive approximation register) principle, by which the conversion is performed in several steps. This is the simplest mode to. In single conversion mode, one conversion is completed between writes to the ADC status and control register 1 (ADCSC1). The following example shows how you can get an ADC conversion result in blocking mode. This ADC has up to 19 multiplexed channels, allowing measurement of up to 16 external sources and up to 3 internal sources. 2 Msamp/sec @V DDA=1. Here is my Init configuration: /**.
