Meh, you could do that with a timer relay. Or did you mean actually making the bread and toppings?
Automated cookie maker?
Nice build!
Has anyone managed to use C to set port values?
Port A works... I can set values, but I need to set values in port B, configured as output.
The library strangely only has function ADBIOSetPortA but not an ADBIOSetPortB.
I tried to copy the function for port A and make the equivalent for B, but it didn't work.
This is the function...
I tried changing ADBReg to 1 (or B), as in the header I can see...

Code:
pascal OSErr ADBIOSetPortA(Byte theAddress,long theChannel,enum value theValue,long theTime)
{
OSErr myErr;
Byte dataTransmitted;
Byte DataBuffer[3], Listen,ADBReg;
unsigned short ADBIOCompletionPPC[3] = {0x14BC, 0x0001, 0x4E75};
ADBReg = 2; // set the port to enumerated A
dataTransmitted = 0; //set up completionflag
DataBuffer[0] = 2;
DataBuffer[1] = (theValue == high) ? theChannel - 1 & 0x03 | 0x40 : theChannel - 1 & 0x03 ;
DataBuffer[2] = theTime;
if (CountADBs() == 0) return errAINoADBs; //no devices connected to the bus
Listen = (theAddress << 4) + 8 + ADBReg;
#if GENERATINGPOWERPC
myErr = ADBOp ((Ptr)&dataTransmitted,(UniversalProcPtr)ADBIOCompletionPPC,(Ptr)DataBuffer,Listen);
#else
myErr = ADBOp ((Ptr)&dataTransmitted,(ADBServiceRoutineUPP)ADBIOCompletion68k,(Ptr)DataBuffer,Listen);
#endif
if (myErr != noErr) {
return myErr;
}
while(!dataTransmitted); // Loop until ADBOp has completed
return noErr;
}I tried changing ADBReg to 1 (or B), as in the header I can see...
Code:
enum port {
A = 2, //Port A
B = 1 //Port B
};Aren't there only two ports?
Actually I meant "C language", sorry
The command
I haven't used C to control one, but usually you have to set up the port direction and mode before using "set". Are you sure there aren't more commands to set up the port?
I don't have the C library to hand.
Hah, sorry, my bad. I got muddled.

Setting port A with the included function works fine (I can hear the relays) but I don't manage to set port B... I wonder why they only gave a function to set port A in the library...
Using the hypercard tool all works fine.
Here are the libraries... just in case.
I use Code Warrior. The sample to get values works, and I modified it to set values.

Only one of the ports has relays, the other uses transistors that won't click.
Yeah… I’m testing port B with LEDs, which I can light with the HyperTalk tool.
In port A I don’t have anything connected, but I know it works from C as I can hear the relays.
I did some more tests and it's clear that the function ADBIOSetPortA does some magic tricks I don't fully understand...
Checking these lines:
And considering that Port A is an enum = 2, I tried this:
As "B" is an enum value = 1.
Then I can get to start changing values in port B, but it's not working right. I think the other lines which do some bit-wise operations need to be changed.
Bottom line: I'm lost

I keep digging... I see that this must be always like this:
As this means that we're sending 2 bytes of data.
EDIT: I think there's no direct command for setting port B and what the Hypercard tool does is to use the command to configure the port, which allows too to set values.
