xuartlite.h

Hi,
Just see the attachment, which describes about EDK.

Hi, thanks for your tip, but that attachment does only explain about going through the EDK-IDE, nothing it helps in how to programming....Most of the syntax remains much ambiguous and I'm confused at often....Well!, if you are experienced in programming, then could you give me some of the sample codes which I could use as a reference for my programming,so that I can learn by programming..The target soft processor is "MICROBLAZE".Sample programs like led interface,lcd interface,RS232,etc....Please if anybody has such codes, your sharing could help in million ways....Thanks....

I've done this code for a Spartan3 1500 board from NuHorizons.. Its a simple project that uses GPLEDs and a UART. Hope this helps...

how to learn edk c code

i can able to do only vry vry simple application as glowing led and reading key.

hellow sir /mam
i am not able to interface lcd with spartan 3e board.i have just to learn the edk.i hv followed steps in lab3 tutorials of xilinx.its showing platgen failed with the errors.plz help me out.

If you create a simple EDK project, it creates 2 SW projects for you, one for testing the memory and the other one "TestApp_Peripheral", there you can find everything you need on how to interface the HW.

XStatus GpioOutputExample(Xuint16 DeviceId, Xuint32 GpioWidth)
{
Xuint32 Data;
volatile int Delay;
Xuint32 LedBit;
Xuint32 LedLoop;
XStatus Status;

/* Initialize the GPIO driver so that it's ready to use,
* specify the device ID that is generated in xparameters.h
*/
Status = XGpio_Initialize(&GpioOutput, DeviceId);
if (Status != XST_SUCCESS)
{
return XST_FAILURE;
}
/* Set the direction for all signals to be outputs
*/
XGpio_SetDataDirection(&GpioOutput, LED_CHANNEL, 0x0);

/* Set the GPIO outputs to low
*/
XGpio_DiscreteWrite(&GpioOutput, LED_CHANNEL, 0x0);

for (LedBit = 0x0; LedBit < GpioWidth; LedBit++)
{
for (LedLoop = 0; LedLoop < LED_MAX_BLINK; LedLoop++)
{
/* Set the GPIO Output to High
*/
XGpio_DiscreteWrite(&GpioOutput, LED_CHANNEL, 1 << LedBit);

#ifndef __SIM__
/*
* Wait a small amount of time so the LED is visible
*/
for (Delay = 0; Delay < LED_DELAY; Delay++);

#endif
/* Read the state of the data so that it can be verified
*/
/* Data = XGpio_DiscreteRead(&GpioOutput, LED_CHANNEL); */


/* If the data read back is not the same as the data
* written then return FAILURE
*/
/*if (Data != (1 << LedBit))
{
return XST_FAILURE;
}*/


/* Clear the GPIO Output

XGpio_DiscreteClear(&GpioOutput, LED_CHANNEL, 1 << LedBit);


/* Read the state of the data so that it can be verified

LED coding in EDK is much easy. I can give that. But much of the hidden registers are unknown. For example to read a data from a port, you can use "mgetdatareg(DIP_SWITCH_base_address,2,1)....". There is another syntax "mread_data_reg". But I don't really know what is the difference between these two...The meaning for the syntax has not been described anywhere.I just had to learn it myself...That is the problem. You must know what are the syntax available for using the appropriate peripheral. I have only few sample coding which restricts my usage at all cost..Some expert could help us.

hi,

i have 4 bit counter. i want to add it to Microblaze processor. Then, through software i want to write initial value from where up counting has to start. While counting happens i want to read the value again through software. Is this possible?

Can anyone provide relevant material ? it would be really helpful.

Thanks in advance
