A little picaxe trouble..

Post by marthais »

I recently purchased a picaxe 08m,14m, and 18x from world education services. after receiving them, i built the programmer circuit (9 pin) described in nuts and volts, servo, and the help files. i plugged it into my computer, using the same(and, i believe, only) 9 pin rs323 port i use to program my basic stamps.
after using the test port tool, i determined that the serial port is port 5. for some unknown (to me) reason, the test function always works, but i cannot download any programs. I have gone over everything, and found nothing wrong whatsoever: powers is fine, serial port is connected...any ideas/suggestion would be appreciated.
if there is nothing i can do, i am leaning to the idea that WES's shipping method ( a plastic tube that did not look static safe, covered in packing tape) had something to do with it.

thanks!

So you know for sure a signal is physically comming out of the serial port?

I have never used PICAXE's but the normal PICs are pretty sensitive.

Still the fact that you cant program any of them is a bit strange. There isnt some security flag or something in the code or on the board?

Did you change your serial port to be 2400 baud?

It defaults to 9600 in windows.

I had this problem with the 05M can't say about others.

Did Picaxe run a special on that group of 3 chips?

I am trying to help a young acquaintance with the set he bought-he is having exactly the same trouble-he tried the 08M and the 18X, and yesterday I tried both of those with him, then we also tried the 14M. i brought the 18X home, and tried 2 other PC's-always the same-the test of the serial port works(voltage on the Serin pin goes from -0.5V to +5V when the button is pressed), but we can't program them using the circuit in the manual.
