Example to Program the SDRAM device present on TC1130
Triboard
This section shows an example to program the HYB39S256160-8 SDRAM device
present on the TC1130 Triboard with a simple LED blinking program.The aim of this
exercise is to Blink a LED connected to the Triboard (P0.7) using only SDRAM. No
interrupts will be used here, only a ‘for loop‘ for delay purposes
1. Write a simple program to blink the LED on P0.7The main program is fairly easy, the
port pin P0.7 is initialized as output and switched on and off. The ‘tc1130regs.h‘ file
declares all the TC1130 registers (i.e. Ports, Peripherals, …)
/*
* blinky.c
* Example for using TC1130 board.
*/
#include <tc1130regs.h>
void delay(void)
{
volatile int i,j,k;
for (i=0;i<5000;i++)
for (j=0;j<40;j++)
k = i+j;
}
int main(void)
{
// set P0.7 as output
P0_DIR_P7 = 1;
// main loop
while (1)
{
// set led on
P0_OUT_P7 = 1;
// small pause
delay();
// set led off
P0_OUT_P7 = 0;
// small pause
delay();
}
return 0;
}
1) The option is fastest setting and verified on TC1130 Triboard.
