Interfacing controller with TM1638

Using Arduino Microcontrollers
1

Hi,

Im trying to display characters on LED display of TM1638,my controller is dspic30f5011.

i have done my code based on datasheet(TM1638),but i'm unable to get data on display.

can some one help me please.

Regards,

can you give the sketch here???

In addition to what gonnie said, also post a drawing of how you connected it to the Arduino, Which Arduino are you usings?

I'm not using Arduino,my controller is dspic30f5011.

connections as below

controller TM1638

SCKL -------------->CLK
CS -------------->STB
DOUT-------------->DIO
DIN -------------->open(I'm not reading any data fromTM1638)

can you give the sketch here???

writing sequence

CS = 0; // enabling the communication
DelayTcy(2);
WriteSPI2(0x44); // Data Command Set with Write data Mode and fixed Address
DelayTcy(10); // Delay of 1us
CS = 1; // disabling communication
DelayTcy(10);
CS = 0;
WriteSPI2(0xC0); // Set the Display Adress initial 0x00
DelayTcy(10);
WriteSPI2(0x40); // Transmission of Data 0
DelayTcy(10);
CS = 1;
DelayTcy(10);
CS = 0;
WriteSPI2(0x8F); // Brightness Control and switch On display
DelayTcy(10);
CS = 1;

and here is my writeSPI function

void WriteSPI2(unsigned int data_out)
{
if (SPI2CONbits.MODE16) // word write
SPI2BUF = data_out;
else
SPI2BUF = data_out & 0xFF; // byte write
}

I'll be of no help, I do not have any knowledge of dspic30f5011.
Sorry.
