Hi all, So I am using AXE026 cable for a while to program my PICAXE chips. But I have a technical question. As far as I know, PC's serial port are working on +/- 15 volts (Correct me if I am wrong please). So does this cable comes with a converter built in to it that reduces this voltage? I...

Hi all, I am almost finished with a 20X2 project and I want to put it in a box :P I want it to be mobile, very light and small...so I am thinking of powering it up with a single AA battery. I have calculated the max current I will need for this application is about 200mA (Basicly some LED's...

Hi all, At the moment I am working with a simple ADC using a pot and transfering the result to a PC. I am using normal download ciruit and I am able to receive ASCII numbers on the terminal. The settings are 9600/None/8/1. Now I am trying to capture the waveform in my scope. I captured...

Hi all, Today I had a chance to use a friend's scope to test something. I programmed 20X2 with the simple program below and then tested the result using the scope: main: high 1 pause 1 low 1 pause 1 goto main And here is the result from the scope (it is a 50MHz digital scope - so I guess...

Hi all, I have a 10k pot (Also tried with 470k pot). I use the following command to send the value which is stored in b1 : let adcsetup = %0000000100000000 let dirsc = %00001100 main: readadc c.1,b1 sertxd (#b1, CR) goto main Now the problem is I receive something like this (In this case I...

Hi all, How can I connect a micro button to 20X2 as an input? The button has 4 legs and I have a regulated 3V as supply to the chip and some LED's. Thanks.

Picaxe 20x2 ADC - 0 to 8 LED's with a POT Hi all, I have 20x2 with 8 LED's on my bread board. I also have some potentiometers (10K, 100k and 470K). First question is which potentiometer to use (Or the value is not important?) Then I want to do something like potentiometer at it lowest...

Hi all, I lost the stereo jack for download cable so I had to cut the cable itself to solder them into my PCB. There are 3 wires in there colored Black, Red and Pink (creamy). I wonder if somone knows which wires are GND, Receive and Transmit? Thanks.

Hi all, I am trying to simulate a program, but it always pop ups for a syntax error in the following line : case ("restart") sertxd("Reseting the program!") b1 = 0 goto main How to write case ("restart") ? this is the full program if it helps answering...

Hi all, I am working on a small project with 20X2. Is there a way to check if an output is already high or low? before actually changing it? for example I need a logic like this if B.0 is high then sertxd("is already high") else high B.0 Note that I do not want to use TOGGLE, in my...

Hi, I want to make a communication between my PC and 20X2. For this, I have connected the Serial In pin (which is already connected to the programming cable and works fine) to pin C.7 (is this ok?) What I am looking for is using a terminal window send the word 'go' to the chip and if chip...

Hi all, Can someone please point me to a quick ADC setup on 20X2? I have 6 LED's that are connected to pins 0 to 5 as output. I had a lot of fun making some LED dance moves once I manage to get the chip to work. Now what I want to do is connect a 10k potentiometer that I have to board and...

Hi all, I am trying a project using with pixaxe 20X2 and it requires sending data through rs232 into hserin pin of the cheap. I have the stereo jacked! rs232 cable so I want to know if I can use it also for sending data to hserin pin of the chip without unpluging it from the socket. is this...

Hi All, Finally my first PICAXE chip is in house now :D I had some questions before I get started expirimenting! 1) On the chip is written 'PIC18F14K22' is this 'PICAXE 20X2' ??? 2) Since I just ordered two chips and one serial download cable, Where can I get softwares to get started with...

Hello everyone, It is my first post here and I hope I can learn a lot from you. I got to know about PICAXE from a friend and he told me it is easy to use and more cost effective than other microcontrollers. I am working on a self project. What I need to do is control (enable, disable) a number...
