We are planning to use the DA14531 module for sensor display unit , the display we are using is a spi display with 6 pins BUSY(input), RES(out), DC(out), CS(out), SCK(out), SDI(out), an i2c sensor with 3 pins (SCL,SDA,interrupt) and a buzzer (1 pin ) and as per our requirement we donot need to use the display , sensor and buzzer simultaneously . so total we need 10 pins to communicate . However the module has only 9 GPIO , of which 4 gpios(P0_0,P0_2,P0_5,P0_10) are shared and have predefined functions (SWCLK,SWDIO,RST,RXTX) . Is it possible to connect a spi display , i2c sensor and buzzer to the module by sharing some pins and managing at the software end ?
If it is possible could you kindly help with the schematic of the connections . I just wanted to clarify it before i buy the development kit .
Thanks a lot for your time and patience .
