there are two i²c devices connected to the bus, and their addresses are 0x48 and 0x77 respectively. If you do not see a device, check the hardware connection, and remember to open the system config inside the i²c.Then still the sample code: Import time Import SMBus addr=0x48 cmd=0xab # open/dviev/i2c-1 bus = SMBus. SMBus (1) # Read and write data, Case 1 Data = bus.read_byte (addr) bus.write_byte (addr, data+1) # Read and write data, Case 2 = Bus.read_byte_data (addr, cmd) bus.write_byte_dat

General Purpose Input Output (Universal input/output) abbreviated as GPIO, or bus extender, simplifies the expansion of I/O ports with industry standard I²C, SMBus, or SPI interfaces. GPIO products provide additional control and monitoring capabilities when the microcontroller or chipset does not have enough I/O ports or when the system requires remote serial communication or control.This article has nothing to say, mainly stickers! But this article i
