How is a strong-current solution different from a low power solution?

Last Updated on：2024-09-11 07:38:27

In a low power solution, two GPIOs (PWM1 and PWM2) are reserved between the Tuya Zigbee module and the MCU for a hardware handshake. The Zigbee module uses PWM1 to awaken the MCU, and the MCU uses PWM2 to awaken the Zigbee module. PWM1 and PWM2 are at a high level by default and are active when they are at a low level for more than 10 μs. Before the Zigbee module or MCU proactively sends a command, it needs to initiate a handshake connection.

In a strong-current solution, serial interfaces are in a listening state. Hardware does not need to connect I/O1 and I/O2.
