Hi, use _Sportl_Ctrl_Reg = 0x6B07; instead of _Sportl_Ctrl_Reg = 8; plus if u want to send 8 bits out of the sport u have to set one less bit value in the last four bits of the sport1 control register. That is if u want to sent 8 bits the value in the lower four bits of the control register will be 0111 not 1000. The _Sportl_Ctrl_Reg = 0x6B07; value sets the serial port in the following state 8 data bits right justified data Internal RFS enable Internal TFS enable Receive FS Reqd with each word Tx Frame Sync Required with each word Internal serial clock Hope the information is worth. I simulated the project and it works with the above setting.
