    28X1 versus 28X2 port designations

    I have a problem using the 28X1 in a project I am working on. I wrote the program originally for the 28X2, but wanted to take advantage of the automatic analog features of the 28X1 chip and rewrote the program. The problem is in the different port designations the 28X1 uses. This is the partial...

    What are the correct pin numbers?

    I get confused all the time in using old and new pin designations of chips. In this case, I want to use the A.0 analog input on the 28X2 (Pin 2) with an Sharp analog IR sensor and entered the following code symbol dist = w0 '------------------------------------------------ 'Activate - ADC0...

    What is the meaning of these sentences?

    I get these warnings everytime I go to the forum web site and I use the advanced search feature. The room to fill in your data to be searched, shrinks also to the point that the words do not fit the room allocated. (In height) What do they mean and how do I correct it? Anyone? Warning...

    Use of PWMOUT with the AXE408 board

    I am using the Axe401 PC Board with the Axe408 Motor Shield to control 2 DC motors, and I have problems using the PWM command. On the Axe408, you are supposed to use S8 and S11 ( C.0 and C.5) as motor direction, and S9 and S10 ( C.1 and C.2) as on/off/PWM (Speed) control for the L293D controller...

    Problems with using the HC-SR04 Sonar Unit

    I am buiding an Object Avoidance car using one of those inexpensive HC-HR04 Sonar Units. To see if a unit is working properly, I build a small circuit to test them. I am using an 08M2, with the following code. The idea is to use an 28X2 as a main chip for other functions while the 08M2 is...

    Can I use a separate Terminal?

    Can I use a separate Terminal with a pre-programmed chip that uses the sertxd command as its output? (And use its program serial TX out pin as the output?) Normally I use this command as a debug tool as I am programming a chip while the serial output is connected to the computer for programming...

    Old versus New Port designations

    I very often look at older designs of projects for ideas, and sometimes run into unfamiliar port designations in designs using obsolete chips. One of the programs I am looking at has this statement symbol buttonA = pin2 'Button is connected to input pin 2 . It uses a 18x chip. I can not find...

    Anybody used the Mr.General robot?

    Has anybody bought the DAGU "Mr. General" robot and used the 28X1 or 28X2 chip with it? I did and could not get it to work with the program provided. It is originally intended to be used with the Arduino system, but a PICAXE program was also available with the included program CD. Any comments...

    Sonar test

    I am in the process of developing a object avoidance toy car and have some problems getting the Sonar Detection system to work. I can not get the circuit anything to read and I don't know what part is not working, the Sonar Unit or the Software. Does anyone know how to trouble shoot it? I am...

    16X2 LCD Code for 18M2?

    The PICAXE website mentions the use of the 18M2 for an available serial 16X2 LCD display product.(AXE033) It also mentions that the code for this 18M2 is available to programmers, but I am unable to find it. Does anyone know where I can download it from? I have several LCDs from other projects...

    Editor - Correcting Mistakes in Program

    I like to make a suggestion for the Editor that would make the process of correcting mistakes somewhat easier and faster. Presently the software will stop at any mistake made in the program when the request "Check Syntax" is made. After the correction is made, the user has to repeat the process...

    Saving Version 6 for later use - Can not program chips

    I have two questions about using the Software 1. How do I save the Version 6 installation file from the PICAXE.com download page on a flash drive so that I can install it on an computer that does not have Internet capabilities, and 2. I have 3 computers one running XP, the others 7, and have an...

    Use of PS2 Keyboard

    I have been trying to use a PS2 type Keyboard with a 40X2 and had not much succes using the instructions on page 129 using D.7 for data and D.6 for the clk. A quick Forum search on this subject revealed that this combination is not as straight foreward as I thought. It seems that this type of...

    8M2 Problems with programs using old code.

    I am trying to use the 8M2 to drive an LCD board, and run into problems, even though I am using code that apparently was OK in 2013.I have looked for samples in the Forum using the 8M2, and found several ones. However, it seems that something has changed, for while the old code apparently ran at...
