Hello, I'm Manfredi from Italy.
I've received my Pluto-P some days ago.
I'm not an expert, I'm a student and I would like to learn.

I've downloaded the file Pluto-P_StartupKit.zip and read the documentation.

Today I plugged my Pluto-P, I've powered it with 5Vcc and the red LED says me that the board is alive

Now I've tried to configure it using the file LEDblink.rbf in the "Sample File" directory... I've set the options>Printer Port>LPT1 Printer, clicked on configure FPGA, and everything went well, a neat bip says me the configuration was successful.

Of course the LED doesn't blink...

I've tried to do my own project on QUARTUS II copying the program ledblink from manual and compiled it (successful) tried to put the new rbf file, but nothing...the LED doesn't blink.

I think maybe there is something wrong with the pin numbers?

I've used pin 91 for clock, pin50 for LED, pin 49 for nConfig and pin for nPaperOut.

...

any suggestion?

thank you

Manfredi

Try to change the BIOS setting (is your parallel port is SPP or EPP or ECP mode right now?).

I'm on a laptop IBM T42.

I've checked the BIOS, my parallel port has 4 modes:

OUTPUT ONLY
BI-DIRECTIONAL
EPP
ECP

At the moment it is in the BI-DIRECTIONAL mode.
Which mode should I try?

thanks,

Manfredi

You can try the first three. The first one is probably what I call SPP, the second one is not standard, the 3rd and 4th are standard but I don't support ECP with Pluto-P.

In FPGAconf, there are three settings in the options/printer menu, make sure you try these too.

Nice, after setting my parallel port to OUTPUT ONLY, ledblink now works!

thank you!

Hi, I had a similar case, there is not output on the LED.
I'm a user for Pluto II doing the example LEDglow.

Pin setup are pin98 for LED and pin97 for clock.

Do i need to disconnect the serial cable when i try?

You should leave the RS232 cable connected.

Try with the LEGglow.rbf file that is in the startupkit before creating your own. Then you can try with your own design (but the pins you are using are wrong for Pluto-II).

The pin assignment for the examples are the default pins for the project?

btw i have some question about the on board LED on the Pluto II.
When i first connect with 5Vcc, the LED is blinking.
during configuration, the LED light up but a little dimmer.
after configuration, the LED is off.

are this the correct state for the LED behavior?

Thanks in advance.

1. LED blinking at power up: that's because we ship with the FPGA boot-PROM loaded with LEDglow or LEDblink.
2. LED dim during configuration: dim means unconfigured, so that's normal.
3. LED off after configuration: that depends what you put in the FPGA. In your case, since you are using the wrong pins, the FPGA is configured but the LED stays off.

For Pluto-II, according to the doc, CLK = pin 10 and LED = pin 25.
