c++ - Why my comparison with an HEX enum fails? -

i seeing weird issue whe comparing hex value stored enum , value read register, have defined chipid follows

enum {   bme_280_1_chipid = 0x60,   bme_280_2_chipid = 0x58, }; 

i have snippet of code in driver chip id check

  uint8_t id = read8(bme280_register_chipid);   if ( ( id != bme_280_2_chipid)  || (id != bme_280_1_chipid) ){      #ifdef debug         uint8_t value = read8(bme280_register_chipid);         debugprint("bme280 debug: read bme280_chipid ");         debugprint(value,hex);         debugprint( " expected ");         debugprint(bme_280_1_chipid,hex);       debugprint( " or ");       debugprintln(bme_280_2_chipid,hex);     #endif         return false;   } 

my read8() funtion

uint8_t adafruit_bme280::read8(byte reg) {   uint8_t value;     wire1.begintransmission((uint8_t)_i2caddr);     wire1.write((uint8_t)reg);     wire1.endtransmission();     wire1.requestfrom((uint8_t)_i2caddr, (byte)1);     value = wire1.read();    return value; } 

however, debug shows

bme280 debug: read bme280_chipid 58 expected 60 or 58 bme280 missing! 

what's happening?

thanks in advance,

regards!

the solution andriano repetti told

  uint8_t id = read8(bme280_register_chipid);   if ( ( id != bme_280_2_chipid)  && (id != bme_280_1_chipid) ){      #ifdef debug         uint8_t value = read8(bme280_register_chipid);         debugprint("bme280 debug: read bme280_chipid ");         debugprint(value,hex);         debugprint( " expected ");         debugprint(bme_280_1_chipid,hex);       debugprint( " or ");       debugprintln(bme_280_2_chipid,hex);     #endif         return false;   }
