hi! i am working on a college project where i need to send sms through pc having VB+ GUI. will be using nxp 2144 or 2146 arm microcontroller and wavecom 2686 gsm module...to start with how do i interface the microcontroller to pc....i mean i might have to consider of a hardware design for the board...pls help me how do i go abt it....sending sms is not the sole purpose, voice interface will be added once sending sms part is accomplished
-> they have given a diagram that is to be used to interface the microcontroller through the USB. <-

Page 34. 10. Application information 10.1 Suggested USB interface solutions Fig 10. LPC2141/42/44/46/48 USB interface using the CONNECT function on pin 17 Fig 11. LPC2141/42/44/46/48 USB interface using the UP_LED function on pin 17
I think that, it is for circuit design, right?
What do you mean by "how should i implement it."?
