Hello everyone.
I have the need to accurately control the speed of a DC Motor.
I'll be using PICAXE at 4Mhz.
The motor itself is rated for 5.3 RPM @24V through the use of a gearbox.
I need to run the motor at 3 RPM, so 56.6% duty cycle.
Is the code below correct to achieve that?
Many...
Hello everyone.
I have been working on a project which is almost completed now.
However, i have came across an issue that i am not able to resolve after many days of troubleshooting.
The project is build on 14M2 chip with AD623 INAMP and a half bridge load cell.
Within the MAIN program loop...
I managed to figure out some of the code but not enough to make the letters display fully.
All letters are cut off at the top and bottom.
The line of text on the screen is THIS IS A TEST.
There is something funny going on.
Any idea on how to fix it and possibly make it larger at the same...
This is what i see on the screen at the moment with the current code below:
' 08OLED_128x64 writes strings to lcd
#picaxe 08M2
#no_data
#terminal 38400
'Display command constants
Symbol TWI_BUFFER_LENGTH = 32
Symbol LCDWIDTH = 128
Symbol LCDHEIGHT = 32
Symbol SETCONTRAST =0x81

Hello.
I am trying to learn on how to use OLED SSD1306 Screen 128x32 pixels.
I have loaded the code into PICAXE Editor but upon Checking of the code i get an error (see attachment)
Any idea what i might be doing wrong?
I am using chip and not 40M
The code i am trying to use was taken from...
Hi Everyone.
I am currently struggling to understand how to make pin assignments using bits.
I have red the manuals and found examples but it is still not clear to me.
Would any one be so kind to explain how to enable internal Pull Up resistors for PIN C.3 and PIN C.2.
I will only be using...
I have used the code below (thanks hippy) to test the system.
'this code will display MAX and MIN values recieved by PICAXE on PIN4 using READADC command.
#Picaxe 14M2
#Terminal 9600

Symbol val = w0
Symbol minVal = w1
Symbol maxVal = w2

Schematics are attached below.
Also see the CODE.

Hi everyone.
I am building a strain-gauge and the controller using PICAXE 14M2 and AD623 Instrumental Amplifier.
Everything is working as expected except for one small issue.
Every now and again PICAXE would get a random reading lower then expected without any changes to the strain gauge.
I...
Hi everyone.
I am trying to run one picaxe to monitor the action of another using simple program.
I am having some difficulties where Serial Terminal only is displaying [00] many times over.
Any idea what might be causing it?
Thanks very much in advance.
Andrei.

Hi everyone.
This is probably a very basic question, but howcan i address all pins at once on a PICAXE18 (X i think, 10 year old chip).
I am making a Christmas jumper with 3D printed Christmas trees on it with 9 LEDS each.
I am creating a program that would run them in a couple pf different...
Hi.
I was looking for some ideas regarding a watchdog to monitor PICAXE program correct operation.
I have came across a Supervisory Watch Dog Timer TPS3813 (LINK)
Has any one used it in the past?
I am trying to figure out how to set the watchdog to monitor PICAXE program running state.
The...
Hi everyone.
I am designing a controller for which is important to stay within programmed parameters.
The Controlling Picaxe (CP) will be sending a high signal on one of the pins for the length 100ms (the time will be adjustable between 40ms and 120ms in the final code) at a time when two...
I have completed putting together a program for my strain gauge and all looks to be working perfect.
However, as soon as i unplug the programming cable the "FIRE" routine is behaving differently.
So when ADC reading is above or below preset value the program goes to FIRE routine.
In the fire...
