Hi all, I have a project with a 28x2 talking to another 28x2 using the hi2cout instruction. I have a problem where the master picaxe is locking up occassionally when implementing the hi2cout instruction. This seems to be happening intermittently, but I definitely know its always locking up at...

Hi all, I have a little robot project where I am reading a servo channel output from a futaba radio control receiver into a 28x1 using the pulsin command. I have this working on my test bench but as soon as I tried powering it from a battery supply it stops working. I have a simple loop that...

Hi all, I have an application where I have a 3 position toggle switch to select a mode. I am using a 28X2 and the hardware input interrupt. I have the interrupts working correctly to detect what position the toggle switch is in. The purpose of using an interrupt for this is to jump straight to...

Hi all, I have a project where I have been using hi2c to send data to another picaxe and it has been working fine. I am using a 28X1. I have an input interupt that is counting revolutions of a motor. I ran into a problem where I needed a pause of about 4 seconds, which was jumping out of the...

Hi everyone, I am interfacing a EM-406A gps unit from Sparkfun with a 28X1 http://www.sparkfun.com/commerce/product_info.php?products_id=465 The gps unit outputs TTL 2400bps serial. I have searched the forum and discovered the 28X1 port c are all schmit trigger inputs. My question is can I use...

I know there must be a simple answer to this question, but I cannot find it anywhere. I have an application where I have 2 x 28X1's. One is setup as the master using the HI2C command: "hi2csetup i2cmaster, %11001000, i2cfast, i2cword" The second is the slave "HI2CSETUP I2CSLAVE, %11001000"...

Hi I have searched the forum but cannot find a solution to a reasonable simple question. I am interfacing my 18X picaxe to a motor drive. I have 8 outputs from the axe to the drive and 4 inputs from the drive. My problem is the I/O to the drive is 24 volts. The drive inputs are transistors so...

Hi I have a project where I want to position a AC motor using a Omron encoder. Currently I have built the interface to the AC motor drive and can control speed and direction of the motor. What I am having trouble with and want advise is the encoder part. I have read through all the posts...

Hi, I've read all the posts and cannot find any help with directly connecting a LCD 16x2 display to a picaxe 28X (not a module display). I am using it in 4-bit mode and I wrote my own initiliastion code. As follows. RS is on PORTC 4 and SE is on PORTB 5. And DB4-7 on PORTC 0 - 3 respectivley...

Hey, I have been experimenting with making my own ultrasonic rangefinder. Im outputing from picaxe to 555 to produce the 38kHz transmit signal. And I can recieve the echo receive as a digital signal by putting it through a comparator. What I am wanting to do is measure the time from...
