I currently am using a 74HC125 to isolate the transmission signals to and from the printer already. There was 2 empty channels in which I can run the LCD module through. When the control input on the 74HC is High the outputs are 'Open" so essentially turned off and not putting a load on the...

Hey guys, Working on a project using a 28x2. I need to communicate with two different devices using Hserin/Hserout. I am polling one machine receiving a response, then polling another device and receiving response. Is there a chip available that will allow you to switch between 2 RS232...

Hey guys, Been reading multiple posts fir the last couple hours. Trying several different ideas without any luck. What I am doing I thought would be simple but is causing me to pull my hair out. After doing math using several variables I need to send the Byte Variable Answer as a HEX number...

Hey Guys, I do apologize for this isn't a direct Picaxe Question, although I have 2 20x2's on my Board. But I was wondering if you could help me out. I built a little demo board using 2 x 20x2 and a RS232 Driver. I was using a Linear regulator but unfortunately it was getting to hot and I...

Hey Guys, Quick Run Down.. I have been playing with Picaxe for about 4 years and have made many Circuit boards.. Im am certainly at the hobby level.. But have learned a lot over the past couple years and have yet to run into something as crazy as this. My Latest Board consists of a picaxe...

Hey there, Just trying to figure out what the following actuality means, for I am not sure on the symbols being used, and or the Terminology. The Sample below is from a friend using a different program/uC, I was wondering if the picaxe is capable of completing the task as well. I am trying to...

Hey guys, quick question I am using HSEROUT to send 200 Bytes in one string to a serial printer. Using Hsersetup B19200_64, %000 I was wondering if the time between each byte sent can be adjusted. Right now its .108ms, i would like to get it down to 54us.. Is this at all possible.. I have...

Hey Guys I have been Searching the web for a while now trying to learn how to use a 20x2 with a TLC5940 Chip. I have been able to extract a little info here and there and have something working now. Although I am far off from where I need to be. Right now I am sending the "12 Bits" the hard...

Well that is it.. You have everything.. Hahah PLEASE HELP! I guess I just want to make sure i goofed and I don't need this cap.. There has to be a reason.. I don't know move forward not knowing why this happened.. Thanks Guys

Thanks guys for the input... I appreciate it... I have put attached the image of the board i designed.. It has been Printed.. I had the setup running fine on the breadboard, but didn't really test the buttons at that point.. For I thought it was a no brainier. I am using RJ45 connectors from on...

Hey Guys.. You have been a great help in the past.. and I know I will scolded for not supplying diagrams and code at this point.. But I wanted to know if anyone has any quick tips to why I am having this issue.. I am using a 20x2.. I have it wired too a Max202 Chip using Hserin - Hserout...

Hey Guys, I'm stuck, and my brain is very confused. I am using Hserin via rs232 to receive an 8 digit (meter) number from a machine. I use the command PTr=2 Bcdtoassci w1,w2 and so on for all 8 digits Then W1=w1-$30 to get Actual number, I have managed to place the higher 4 numbers in one word...

I am using a 20x2 with max7219.. I have the CLK, DATA, and LOAD connected directly from chip to chip.. No resistors in the line, or resistors from the lines to ground or 5 vdc.. Is this correct? Should I tie any of these lines high or Low with a resistor? Or install any in the lines it self...

Hey Guys, I was wondering if I could get some input.. I am looking to build add on modules for my Honeywell Home security System. I installed the system myself last year and am pretty educated in that department. As well I have build and played with several picaxe chips using serial in/out...

Hey Guys, I salvaged a Stepper Motor and Controller Board from a Vending Machine.. And thought I would try and control it with a Picaxe 20M2.. I am a Newbie.. So please forgive me if the "Code" or Terminology I use is not 100% Accurate.. I have the board wired to my 20M2 as shown in Picture...

Hey Guys.. I am working on a project with a 20x2.. I need to pull 2 VAC triggers from a machine. The AC voltage is 7.5 VAC.. and I need to convert this to logic input on Picaxe. Is there a simpler and easy way to do this other then using a $5 Opto-Isolator for each input? I did some research...

Hey Guys, I was playing around on the weekend trying to interface a RTI (TV Remote) which has a main "Brain" With RS-232 output. I was able to track down the TX and ground pins and interfaced with a Picaxe 28x2 using Serin on pin C.0. I have it working very well. Although when I click to...
