Single Conversion Mode - ST STM32F413 Reference Manual

Temperature sensor, V
•
The temperature sensor is internally connected to ADC1_IN18 channel which is shared
with VBAT. Only one conversion, temperature sensor or VBAT, must be selected at a
time. When the temperature sensor and VBAT conversion are set simultaneously, only
the VBAT conversion is performed.
The internal reference voltage VREFINT is connected to ADC1_IN17.

Single conversion mode

In Single conversion mode the ADC does one conversion. This mode is started with the
CONT bit at 0 by either:
• setting the SWSTART bit in the ADC_CR2 register (for a regular channel only)
•
setting the JSWSTART bit (for an injected channel)
• external trigger (for a regular or injected channel)
Once the conversion of the selected channel is complete:
•
If a regular channel was converted:
–
–
–
•
If an injected channel was converted:
–
–
–
Then the ADC stops.
13.3.5 Continuous conversion mode
In continuous conversion mode, the ADC starts a new conversion as soon as it finishes one.
This mode is started with the CONT bit at 1 either by external trigger or by setting the
SWSTRT bit in the ADC_CR2 register (for regular channels only).
After each conversion:
•
If a regular group of channels was converted:
–
–
–
Note: Injected channels cannot be converted continuously. The only exception is when an injected
channel is configured to be converted automatically after regular channels in continuous
mode (using JAUTO bit), refer to
