Hi,
I’ve a problem, I would like to send a precise number of pulses in a digital port, with a frequency of 10Khz. With the code below I can get max 1Khz.
is there a solution?
OutputPort Puls_X = new OutputPort(FEZHydra.Pin.PD19, true);
Int32 X_Current=0;
Puls_X.Write(!Puls_X.Read());
if (Puls_X.Read())
{
X_Current = X_Current + 1;
}
Thread.Sleep(1);
Thank you.
Sorry for my bad english.
@ ianlee74 - sorry but I do not understand
On reflection, that code share of mine has a really bad name. It is not a function generator as in signal generator, it just parses the gcc .map file and generates the C# managed functions to call into the RLPLite code.
I am not sure if there is anything on Code Share for this, but I have a custom firmware that is based on the latest GHI firmware for the Hydra that includes a Signal Generator similar to what is available in the Premium library. If you are interested you can get more info on the following thread

Alternatively, you would need to implement this using RLPLite to achieve the 10kHz frequency for a specific number of pulses.
Sorry, I sent you the wrong link. I meant the firmware that taylorza linked to.
@ ale_zenigata - You might want to take a look at the code share I put up today. It is an RLP Signal Generator for the Hydra. You can pass it pulse timings in microseconds.

You can achieve it by using SPI if you can use a SPI enable output pin.
Sending a pulse is equivalent to send a 0xF0 byte (or 0x80 for a shorter pulse).
Configure your SPI to 80kHz and create a buffer for the number of pulses you want to send.
