Hi,
I've completed a few projects where the circuit board is housed in a plastic box and needs to operate outdoors at close to 0 deg C ambient with medium to high humidity and have found that they behave erronously as the temperature drops.
I had a read of the microchip datasheet and the max...
Hi,
I need to interpret ascii data sent from a software via the programming cable and perform relevant tasks on a 28x2, but am having some trouble parsing the data.
the software is an autoguiding software (guidemaster) for sending correction pulses to a telescope controller when a star drifts...
Hi,
i'm trying to interface a picaxe (20M2/X2) to a software on a PC, where the software will send certain ascii strings and the picaxe would need to interpret them and either send a response back immediately or perform an action based on the string.
the software is a telescope control...
Hi,
sorry if this is a repeated topic, I wanted to establish a wireless to serial link between my laptop and a 28x2 picaxe as well as the 28x2 picaxe and another 20x2.
so Laptop -><- wifi -><- transceiverA -><- serial conn to picaxe 28x2(picaxeA)>
also want a link as below
picaxe...
Hi,
I've built a stepper motor controller using a 28X2 and was using a wired control pad with simple momentary switches. each would raise a pin high and the stepper would step at a different rate depending on the pin raised.
I have a simple loop that scans the 5 pins for a switch press.
I...
Hi,
I'm trying to build a precise dc motor speed controller with optical feedback and needed suggestions on which path I should take as there are several options available.
have searched through this forum and found pwm was the most common method for speed, but its not truly variable in a...
Hi,
I just got a 434Mhz RF Transmitter receiver from sparkfun and am having trouble receiving transmitted data.

Hi,
I needed help with writing code for a stepper control application that includes acceleration and deceleration, and the option of different square wave outputs to send to a seperate stepper driver depending on keypad selections.
(I'm completely new to picaxe's)
I need the picaxe to just...
