Hi bleeb

When I try to compile it give me a syntax error:

"Line119: Prototype variabele already declared readAnalogChannel"



;Import "k8055.lib"
Prototype.l _openDevice(cardaddress.l)
Prototype _closeDevice()

Prototype.a _readAnalogChannel(channel.a)
Prototype.a _readAllAnalog(aData1.a ...

startup wrote:problem solved.
embarrassingly i gave the wron parameters in the test program

both modules work as expected

Can you please post the complete modules and main program in zip because I can not compiled it

Kind regards
Stephane

Hi,

I rewrite the code with the syntax of PureBasic. Iqs that correct.
How can I use the functions from the library k8055.dll



;Import "k8055.lib"
Prototype.l _openDevice(cardaddress.l)
Prototype _closeDevice()

Prototype.a _readAnalogChannel(channel.a)

Can you please repley to my post with my example of SPI example:

Hi,

no, I don't want to reply.
I'm helping nearly always and on most problems if I think I have enough knowledge to do it.
But at some point I have to stop.
My time is ...

there is a simple way to check the syntax:

Press the compile button.

Or, from the menu, 'Compiler'->'Syntax check'

I 'm only a beginner with PureBasic .
I would like to apply the libarary K8055 from Velleman .
I tried to declare all functions with the syntax of PureBasic .
Can someone look at once if everything is correct according to the syntax and semantic.

This my code (trial)

Hi,

I don't know what I should do with you...

I gave you all to do this task.
So simply do it.
Or if something is not working, than tell it and I'll try to fix it.

But if you are not able to use the code which I wrote to todo what you need,
than I don't know what I can do for you. Really.

Or ...

Hi,

I changed my SPI stuff above to be able to transmit more than one byte with SS low.
The demo at the end should do a reset on the AD9833.

Pseudo example:

fout = 400Hz ; fMCLK = 25 MHz

Freq_Reg = (fout * 2 ^ 28) / fMCLK ==> (400Hz * 2 ^ 28) / 25Mhz = 4295 (dec) = 0x10C7 (hex) = 0001 0000 ...

Hi,

SPI:
MISO - input
MOSI - output
SCLK - output
SS - output


RS232:
CTS - input
DTR - output
RTS - output
TXD - output

So yes, it is possible.
But you need to adjust the voltages:

SPI has normally 5V levels (or 3.3V)

RS232 is at least -9V and +9V
To adjust the output pins is not a big deal ...

Hi,

you have the code for the I²C. So where is the big problem to write the code :?:

Anyway, here is the slowest implementation of SPI (but multiple ports possible):

;
; SPI over RS232
;
; MISO - CTS
; MOSI - DTR
; SCLK - RTS
; SS - TXD

Hi,

I think you are totally wrong here.
For that what you are want todo, you need a microcontroller and not a PC.
Or a microcontroller between your PC and your other hardware.

And if you don't have the knowledge about all that, than you need more intelligent 'ready' hardware.
Like USB ...

As mentioned in your other thread:

Use a microntroller between, which translates serial commands into SPI.
Or use a LPT port.
A serial port direct needs a lot of hardware around to adjust the voltage levels.

Hi all,

I have need SPI communication for the AD9833 is a DDS chip and communication with the serialport.
I have ready the hardware in the form of a board from analog devices.
I would now like to program the AD9833 with pure basic and communicate via the SPI protocol .
I never go a module where ...
