Hi, we connected BMP581 to a Raspberry Pi with one with hard-wired address 0x46. Sometimes sensor has address 0x46 sometimes 0x47. Sometimes even both addresses when using i2cdetect. How can it be? Can address still change after boot? Kind regards, Jule ... View more

Hi,   I evaluating the NVM of product BMP581 and struggle with the reading procedure. I followed instructions in datasheet and this is my Python code:        self.writeRegister(0x37,int(f'11000000',2)) # Switch to standby         time.sleep(0.1)         x28 = format(self.readRegister(0x28),"08b") # Read status         if x28[4:7]=='001': # No error and ready             for reg in range(0x26, 0x22, -1😞                 #print(f'Loop {reg} Register {0x00+reg}')                 self.writeRegister(0x2B,int(reg)) # Write address                 self.writeRegister(0x7F,int(0x5D)) # Write first read command                 self.writeRegister(0x7F,int(0xA5)) # Write second read command                 #time.sleep(0.1)                 x28 = format(self.readRegister(0x28),"08b") # Read status                 if x28[4:7]=='001': # No error and ready                     NVM1 = format(self.readRegister(0x2C),"08b") # Read register                     NVM2 = format(self.readRegister(0x2D),"08b") # Read register                     uid= uid + NVM2 + NVM1                     print(f'Register {hex(reg)} read {NVM1} {NVM2}!')                 else:                     print(f'NVM read {hex(reg)} not ready')         else:             print(f'NVM not ready')   All readings from the registers 0x2C and 0x2D always 0x00. What is wrong? Kind regards, Jule ... View more
