interfacing controller with TM1638(LED DRIVER)

[khaleel]

Hi,

compiler:MPLABC30\v3.31
IDE:MPLAB V8.88
controller:dspic30f5011


I'm trying to communicate my controller with TM1638. As a first step i have thrown some data on LEDs through SPI protocol.Unfortunately I'm unable to get data on display.

The bits i have configured for clock polarity and phase are


SPI2CONbits.CKP = 1; // Idle state for clock is a high level, active state is a low level
SPI2CONbits.CKE = 0; // Serial output data changes on transition from Idle clock state to active clock state
SPI2CONbits.SMP = 0; // Input data sampled at middle of data output time

here is my writing sequence

CS = 0; // Enables communication
DelayTcy(2);
WriteSPI2(0x44); // Data Command Set with Write data Mode and fixed Address
DelayTcy(10); // delay of 1us
CS = 1; // Disables communication
DelayTcy(10); // delay of 1us
CS = 0; // Enables communication
WriteSPI2(0xC0); // Set the Display Adress initial 0x00
DelayTcy(10);
WriteSPI2(0x3F); // Transmission of Data '0'
DelayTcy(10);
CS = 1; // Disables communication
DelayTcy(10);
CS = 0; // Enables communication
WriteSPI2(0x8F); // Brightness Control
DelayTcy(10);
CS = 1; // Disables communication

Is every thing fine with my configuration and writing sequence or any changes need to made?
