5.2 Reset
F8L10D default power-on reset the module immediately, there is no boot and
shutdown pins, but provides a hardware reset pin, digital input, active low, if the normal
work need to reset the module, need to do this pin .
Module because of the complex operating environment, long working hours, there are
crashes, false connections and other unusual problems. When an exception occurs, how
to automatically restore, the application module design must be fully considered. We
recommend two ways:
1), the module's main power supply can be controlled, turn off the main power supply,
and then re-power. This way the most thorough, most reliable, unattended equipment, it is
recommended in this way.
2), control RESET pin (reset) is low 200ms, the module hard reset, similar to the
processor hard reset. This method is generally used for battery-powered handheld
devices, if this method can not be restored, you may need to manually power-off.
For hardware reset circuit design recommendations (
strongly recommended to use mode
two
):
1, the use of micro-button to manually reset, press the reset pin to the ground, open
and disconnect the connection to the ground, as shown below.
Figure 5-3 Reset Circuit
2, the use of MCU control transistor to pull down the RESET module hardware reset,
as shown below:
