I had seen the C953 and but overlooked that it covers also the T5400 which I had been searching for. Thanks!
What bothers me is that in the data sheet on page 7 http://www.epcos.com/web/generator/Web/Sections/ProductCatalog/Sensors/PressureSensors/T5400-ApplicationNote,property=Data__en.pdf;/T5400_ApplicationNote.pdf
it says that the low resolution mode is obtained by #define C953_LOW_RES_LOW 0x01 // 2 ms Conversion Time
while in the sensortag hal_bar.c. it says #define C953_LOW_RES_LOW 0x00 // 2 ms Conversion Time
Also for te other 3 modes there is a difference either 0x09, 0x10,or 0x11 while in the sensortag hal_bar.c I found below code:
#define C953_LOW_RES_STANDARD 0x08 // 8 ms Conversion Time
#define C953_LOW_RES_HIGH 0x10 // 16 ms Conversion Time
#define C953_LOW_RES_ULTRA_HIGH 0x18 // 64 ms Conversion Time
Any advice? maybe just ignore and use the values given in the hal_bar.c
