One pulse mode
One Pulse mode enables the generation of a pulse when an external event occurs. This
mode is selected via the OPM bit in the CR2 register.
The one pulse mode uses the Input Capture1 function and the Output Compare1 function.
Procedure
To use one pulse mode:
1.
2.
3.
Load the OC1R register with the value corresponding to the length of the pulse (see the
formula in the opposite column).
Select the following in the CR1 register:
–
–
–
Select the following in the CR2 register:
–
–
–
Using the OLVL1 bit, select the level to be applied to the OCMP1 pin after the
pulse.
Using the OLVL2 bit, select the level to be applied to the OCMP1 pin during the
pulse.
Select the edge of the active transition on the ICAP1 pin with the IEDG1 bit (the
ICAP1 pin must be configured as floating input).
Set the OC1E bit, the OCMP1 pin is then dedicated to the Output Compare 1
function.
Set the OPM bit.
Select the timer clock CC[1:0] (see
