Hi. I need some advice please on connecting an 18M2 to my PC so that I can send serial commands to it to set certain output pins high or low. I don’t need the 18M2 to reply to the PC. I do not need to be able to program the 18M2. I do that off board. I have actually done this type of thing...

Hi. I would appreciate a little help with some code please. I am using an 08M2 to control a water heater. I turn on the water heater by making pinC.4 high by simply momentarily pushing a push to make switch which is connected to 5V and pinC.4. This then makes pinC.0 go high which operates a...

Hi, I just want to flash an LED from the keyboard of a PC running Win7 64, an AXE027 cable and the PIC 08 proto board. I'm using the 08M2 chip. Here's the code I'm using: main: serin 3,N2400,b1 if b1=1 then high 4 endif pause 1000 low 4 goto main It works fine in the simulator so I'm...

Perhaps someone could clear up a slight problem I am having with Program Editor (ver 5.5.1). I am using an 18M2 with an NKM coder/decoder to send text strings to 6 different 08M2s (with NKM decoder also). I am using the serout and serin command to do this. My problem is concerned with the...

Hi, Is it possible when using the simulator to view the state of a bit variable? I can view the byte and word variable no problem but can't find the present value or state of a bit. Also,I have the latest version of the Program Editor, 5.2.11 and it is really superb but it doesn't seem to...

Hi, I will be using a PICAXE-14M2 at 4Mz to pulse out 16 different pulses to to eight PIC-08 chips. Each PIC-08 will receive two of these pulses turning a latching solenoid ON and OFF. So when the 14-M2 pulses out for say 80ms the first of the PIC-08s will turn ON solenoid no.1 and when the...

Hi, I know this is a common problem which has been dealt with on the forum before many times but I’d really appreciate any help you could give me with programming a PIC 08 chip. I've read as much as I've been able to find on the forum about this problem and I hope I haven't missed something...

I am driving a 500 ohm relay directly from leg 5 of a PIC 08. I am a little puzzled by the placement of the flyback diode for the relay. Is it in the correct position as shown in the attached pdf file? Thanks in advance if you can help. Regards Dermot

I'm using an L293D chip to power a solenoid valve. It receives its signal from an 08 chip. I'm using leg 3 and leg 7 of the o8 chip to power leg 2 and leg 7 of the L293D. Do I need to have a resistor between leg 3 0f the 08 chip and leg 2 of the L293D and between leg 7 of the 08 chip and leg 7...

Hi, I have a 1.2v output from a separate timer which I want to connect to leg 4 of a picaxe 08 chip. I need at least 2v to get a logical 1. I can use an op amp to step up the voltage but it means an extra chip and two extra resistors. I also have a 3v supply in the circuit which would be ideal...

Hi, I'm using an L293D to drive a solenoid. I'm using pins 2 and 7 to trigger the pulse and 3 and 6 are connected to the solenoid.4,5,12,13 are of course grounded but I am not using 9,10,11,14,15 and I don't have these pins connected to anything. Pins 1,8,16 are powered at 5V. Should I have the...
