Can someone please direct me as the Picaxe 40X2 DIL labelling in Picaxe manual 1 does not match the the 40X2 QFN pic available on Picaxe store which appears to have 44pins in total although we believe some are not connected? Basically is there a reference available for the labelling of the...

Hi All Is it possible to use a 14M2 to control output to a LCD screen with I2C interface. This is the LCD being considered If so, please can you direct me to any resources that may be available so I can understand the easiest way to get some basic alpha numeric text output to the LCD from a...

Thanks for looking, I am trying to use the signal output from as brush-less motor controller to detect if the power to a motor should be stopped. The brush-less controller is from Ebay and makes use of the HAL sensors on the motor. The controller works well but has a method to cap the current...

Hi All I have read a few articles about using a PIC to limit the current to an LED by measuring the voltage drop across an LED using the ADC input pin. The current to the LED is controlled using the pwm command. The PWM output to the LED is adjusted to control the length of time the LED is...

Hi, thank you looking. Im struggling with what should be simple but I cant get my head around it and I am just going around in circles. Its even harder as we cant deal in fractions! I have an ADC input that ranges from 340 - 1000 Id like to take the input and use it to set the speed of a...

Hi All I have set up a 14m2 to drive a brushless motor controller. The 14m2 is connected to a foot pedal (variable resistor (10K)). I have set the 14m2 to read the ADC in via a voltage divider. The voltage divider is 10K resistor and then the 10K foot pedal. When connected to the pedal the...

Hi All Not directly related to a Picaxe but I am hoping someone can help. I have a battery (29.2v DC) and its made up of Lithium cells. Inside the battery there is a capacitor across the positive and negative wires which then lead directly out of the battery. The capacitor is a 35V 220uf...

Hi I am trying to store a binary value o or 1 into a permanent location which remains when the chip is switched off. However no matter what I do the code always defaults to displaying a value which represents a zero value being read from the eprom. So if I try to write 1 to location 1 eg write...

Hi All I was just wondering if it was possible to use an 08m2 to ready the data from a Wii nunchuk. I'm especially interested in the data from a the joystick on the nunchuk. I`ve read lots about Arduino doing it so I guess it can be done but has anyone tried it? Any pointers or tips will be...

Hi All Has anyone had any experience of using a Picaxe to create a Coulomb counter. I have created a circuit to measure the Voltage of a Li-ion battery with a range 24-29V, however its not very accurate. I read a thread once and I think is was here about someone who had created a circuit to...

HI The Vdd appears to default to 5V when I run my simulation, However I require a 14m2 to only switch on when a switch is pressed as the 14m2 is part of a sub circuit. Please can you tell me how to switch off this defaulting to on. So that the Vdd does not automatically switch on to 5V for the...

Thanks and thanks again for looking: I have a circuit that when powered using a momentary switch, causes a couple of transistors, N-mosfet and 14m2 picaxe to stay on until a switch is pressed again to shut down the circuit. (If your interested here is the circuit hyperlinked to this text and...

Hi All Can someone help me out or point me to some ideas please. I currently have a 30V battery operated device. The circuit is split into 2 halves, 1 side operates at 22-30V from a battery and the other side of the circuit operates at 5V which takes the power from the 30V supply via a 5...

Hi (thought Id start a new thread although kind of related to my last thread on space saving and programming SMD pics). Im creating a PCB which I want to be as small as possible. I only have access to software which allows 2 layers only (freeware Diptrace). So I need to make use of the limited...

Hi Thanks for looking. I am wondering how to go about programming surface mounted chps. I am making a PCB and Id like it to be as small as possible. I may make many of these PCBs and will be using the surface mounted 14M2 and surface mounted 18M2. Im not sure how to go about programming these...

Hi All I am trying to source a bluetooth remote control for integration into an ongoing project. Currently I use a 14m2 to control a brushless motor controller board. The 14m2 receives input from 3 wired switches which are stop/stop, speed up and slow down. Id like to make the unit remote...

Hi All I would like to use (if possible) the 18M2 chip on my own custom PCB to drive an OLED such as the one used in the AXE133Y module. Is there a schematic already available for this which will show me the required connections. I have looked but no luck so far? I don't want to use the AXE132...

Hi All Thanks for looking. I have what is probably a simple problem to solve if you know what your doing, which I do not!, so I need help please. I don't want to try and solve it with trial and error as I usually would due to the costs of the micro pucks I use which are blown easily. The...

Hi Please can someone help with this. I have a 14m2, I was using this chip with an LCD screen called texstar. I have been using this combination for a couple of years without problems, However the texstar LCD from coolcomponents is no longer available. I need a similar low porfile LCD for our...

Hi all I have a small circuit powered by a 4.2v battery. The circuit has an 08m2 at its heart. The circuit is very simple and essentially monitors a membrane switch and when depressed it then activates an n channel fet that sinks a puck to power a cree led. It all works perfectly except that...
