I am using the Adafruit BME280 with an STM32l432KC and have asked for help on another occasion. At this point, I am just trying to confirm communication between the sensor and the microprocessor using sensor address 0x76 << 1, id register 0xD0 which should return 0x60 value to Tera Term software. I have attached the BME28 pins to STM32l as follows: SDI to D4, SCK to D5, GRD to GRD, 3.3V to 3.3V. I am not using a pull-up resistor on SDI or SCK pins account BME280 shows to have 10K pull-up incorporated into the sensor.
Please review the attached files which contain my code and TeraTerm output. Any suggestions to get this code to work would be greatly appreciated.
Thanks in advance,
