Many thanks, Bart, I will try your scanner tonight after work :) This way, I can know if the LM75 works correctly. But as for sending an acknowledge, I don't...
... NOT EVEN A K8005 STEPMOTOR CARD! ... I'm not sure how the K8001 is programmed. It *might* be possible you can access other I=B2C components, by using other...
... I never tested it with an LM75, but I think it should work. But if the results are negative, this doesn't have to mean that the LM75 is not working...

... I have just asked Velleman for the PIC code (is that what you call it ??) For the K8001 and K8005. Wait and see what Velleman's reply will be.. Keep your...
... related to the PIC code. I don't know much about stepper motors, or what the signals should look like. But if there is a problem, it will be the PIC...
Hi; I have a K2607 temperature sensor card wired to a K8000. I am using VB 5 and I am having problems getting a clean shutdown of the outputs (the relays...
... Yep.. That was my thinking. Except for the possibility that i made on both my K8005's the same mistake when build them :-0 I got a suggestion it might be a...

that way you make your own shmitt-trigger, like the one in the K2607, but with code ;) ... _________________________________________________________________ ...
... I don't have the schematics for K2607 available, and I can't find them on the velleman site anymore. Anyway, I don't know all features of this circuit. Can...
... The K2607 temperature sensor does not have a shmitt-trigger, i think. A shmitt trigger has a ON/OFF output as far as i know. The sensor on the K2607 has a...
Hi; I put the K2607's schematic on my page at earlscomputers.com. I converted Celsius to Fahrenheit. I have 5 deg difference between the on and off temps. I...
Once again, many thanks Bart for your help :) I tried yesterday ur I2C scanner and yes, it detected it, but... ?? Your scanner says the address is 158...
... The circuit in my k2607 manual is different. R1=5K6 The pin 2 and 3 of the LM741 are switched. And C5 is new for me. In the k2607 circuit in the manual pin...

Hi Jukka, Thanks for the links. I'm on holiday in Alaska so I'm now using internet cafe' PCs and can't examine each schematic for the one I need. Can you...
Hi; I will have to compare the schematic to the circuit board. The schematic I put on the web I received from a friend of mine. I misplaced my original. If it...
... The problem is the nature of the AD channel. The temperature varies slowly. As a result the voltage given by the k2607 varies slowly. Then the voltage...
Wow, Bart, very valuable information :):) But so far I can't help u much more, coz it's beyond my knowledge. Yesterday I tried again ur scanner and it works...

Hi Good fishing there ? :) I'm almost ready with my schematics. I will send them as soon as possible. Work limits hobbies :( Jukka...
... But I suppose you get the picture? You might try the following code: i2Cstart(); i2COutput(LM75_1 | 1); int msb=i2CInput(); int lsb=i2CInput(); ...
