Just modified some code to save data into eeprom so it can be used between power downs and go this compiler error: eeprom 112,(4) ^ Error: EEPROM cannot be used within If blocks This looks fairly fatal for this construct. Couldn't find it documented anywhere, is there any...

I have an RFID tag reader (based on marks code snippet) which is reading serial data from an RDM6300. The reader is being used to detect presence of one of two cats and dispense food depending on which one it is. To calculate the food requirements, I need to track the total time over a 24 hour...

I was originally going to reply to this thread, but think a new thread is more suitable. Can someone explain exactly which chips the 'table' commands work with? Programming Editor (5.5.0) 'Quick Syntax checker' states: Command Chips applies to table 20X2, 28X2,40X2, 28x1, 40X1 tablecopy 14M2...

PICAXE driver for JY-LKM1638 multi display module Originally inspired by this thread http://www.picaxeforum.co.uk/showthread.php?18788-Worth-a-punt I thought the following may be useful for others. Although not finished regarding the hardware, I thought the code may be useful for others who...

I think I know the answer to the following question, but feel obliged to ask on here to ensure I have investigated all options. From the Microchip datasheet for the 08M2 http://ww1.microchip.com/downloads/en/DeviceDoc/41441B.pdf I concluded I could use c.5 as an output pin (c.3 is the input...

I am running a program in an 08M2 on the AXE091 development board. If I leave the computer connected via the download cable with the PICAXE program running, shut down the PC and then power it up, the 08M2 is reset. As the 08M2 does not have a reset pin, I do not understand how this is...

Being relatively new to PICAXE I have posted several questions for clarification about commands from Manual 2 V7.8. Today I wanted to clarify what to do with the address in a READ or WRITE with a word variable. There is no example of using the word variable in the manual. The top 5 entries in...

Having struggled with the concepts of pin and outpin, I hope someone can assist. The following code simulates and runs correctly on chip #picaxe 18m2 #no_data dirsb = %11111111 ;Set port b as output dirsc = %00000000 ;Set port c as input symbol dataout = b0 ;w0 and bit 0 to bit 7 symbol pad =...

Having just acquired an 18M2 (from an 18X) , I am desperately trying to get my head around the port.pin and pinport.pin notation. I have taken Technical's quote in #10 of this thread as my crutch (its on the wall!) Then I also have to understand port direction!! I cannot find an example of...

I have been using the AXE033 happily for some time and decided to 'improve' the display output by adding a degree symbol. The User Manual (V4.3) shows the degree symbol in appendix B as $B2. This however produces another character. I found from the forums that the actual character is produced...

I am trying to analyse an extremely intermittent fault on my Boilermate 2000 central heating system. It basically uses a micro-controller to control the pumps and receives input from 3 temperature sensors. I suspect one of the temperature sensors is faulty but very intermittent. I have...
