Hi :D I am using the DS1307 with the AXE133Y display, for a clock. I want to be able to set the time using switches. I have made some code which will produce decimal values for seconds, minutes, and hours. However, the DS1307 wants the numbers in the hex equivalent. For example: I set the time...

Hi :) Pretty much, what I've got is a pic 18m2, connected via i2c to the DS1307 RTC, which is outputting time, date and temperature to and OLED display, and outputting seconds onto LEDs via 8 bit serial to parallel shift registers. I only have 10 LEDs on the shift registers, so before I scale it...

Hi :D I live in the UK and I can't seem to find somewhere to buy a 5v wall adapter (3 pin uk plug) and socket to plug the other end of the adapter into which I can solder onto a PCB to deliver 5v power for my picaxe circuit. Does anyone have any ideas. Thanks :D

Hi :) Very simple question, will using 9V to power the AXE133Y OLED display damage it in any way. The datasheet specifies 5v, but I have used 9v on 18m2 chips before, even though the site specifies 4.5v, and they worked fine. Thanks :)

Hi :) I have a pic 18m2 wired up to the DS1307 time chip via I2C. As an output, I have two 7 segment displays connected to two 4026 chips. So a pulse out of B.5 will increment the value on the 7 segment displays and a pulse out of B.6 will reset the displays back to 00. I would like to made a...

Hi :D I am just starting to learn basic for pic after using logicator. I am building an LED clock that uses shift registers and a ring of LEDs around the edge of the clock for the seconds and four 7 segment displays for the hours and minutes (controlled by 4026 chips). The chip I am using is an...

Hi :D I am having an issue with the budget serial OLED module. I have it connected to a pic 18m2 chip which simply tells it to display variable A, and increment it every second, then display variable A again. It does this for maybe 6 seconds, then stops showing any new data sent to it. I am...

Hi guys :D I would like to build a simple 'keyboard' using a pic circuit. The 'keyboard' will only have the arrow keys and enter key controlled by push to make switches. The output will be an output pin soldered appropriately to a USB connector. My question is how exactly does a normal USB...

Hi all :D I've been looking through the interfacing manual for PIC chips to computers and I was wondering if it is possible to use output from a picaxe chip to use as user input in a c++ (and perhaps opengl) program. So i.e. a simple c++ program, wait for input 1 on picaxe to go high. When it...

OK, thanks, its basically a multi-function game dice. Not sure if thats how to attach...

Hi all :D I'm having a bit of a problem in logicator (flowcharts), it seems that most times a call up a subroutine, I get "stack error - the same variable has been used to repeat procedures which are nested within each other!" From then, the program just stops simulating. I do have procedures...

Hi all :D I would like to use the picaxe 18m2 chip to take input from the user, (potentiometer connected to ADC, and a few switches) and based on the input from the user, output text or numbers to an OLED screen. I think i understand that another 18m2 chip is used to drive the screen, but my...

Hi all! For some reason, in the flowchart interface of logicator (not sure about basic), when I try to divide two numbers, say 30/60, I don't get a decimal answer, making my calculations extremely inaccurate. If anyone knows how to do this please post. P.S. I will be using this in a wait, and...

Hi all, I need a way to compare 6 variables and find the biggest one using the flowchart interface of PIC logicator. I would prefer not to use a massive array of checking if one variable is bigger than another as that would be very complicated and waste a lot of memory. Thanks :D
