If I use, as inputs, the same datasheet values, the two functions return, respectively, 13. I developed, in Simulink, two different functions: one to calculate the true temperature, the other to calculate the true pressure. Therefore, being B7 = 1171050000 the value 70003 would be returned, as p, instead 69964.

The if condition is not respected: in fact, 0x80000000 means 2147483648 in decimal. Moreover, a pressure value of 69964 Pa appears irrealistic: by considering the figure 5, it means an altitude of about 3000 m over the sea level (I do not know if the Bosch research center is so high). While the temperature reading appears correct, there are some problems with the pressure: in my opinion, by considering the “calculate true pressure” in the datasheet, the coefficients B6, X1, X2, X3, B3, B4, B7, p, UP, are returned when the value 0x2E is write into 0xF4 register: in fact, similar values are returned to me, from my BMP180, when I write the 0x2E value into 0xF4 register, instead of 0x34 (pressure, with OSS = 0). 65x Cable Jumper Male The references are packaged inside a transparent plastic case.By using an Arduino Uno board (programming in Simulink), I am tring to read data from a BMP180 sensor and to calculate the true temperature and pressure, by following the functions shown in figure 4 (pag. 10x Male-FeMale Cables 20cm Jumpers Dupont 2,54 1x Adapter Battery 9V 6F22 Jack Connector DC 1x 5V Stepper Motor 28BYJ-48 + ULN2003 Driver Boat 1x LED Diode Assortment Kit 30 pcs 5mm red, green, yellow 1x 4x4 High Quality Keyboard Matrix Push Buttons 16 Touch Keys 1x Infrared Wireless Remote Control IFR NEC HX1838
