    External eeprom read/write problem

    Thanks guys, my problem seems to have been more or less along the lines of where you both were asking questions and making suggestions. I have tidied up the mix of bytes and words etc. and everything is running now as I had hoped. The lesson learned is to be much more careful and knowledgeable...

    External eeprom read/write problem

    I think you guys' suggestions and questions have pointed me towards where I got all mixed up regarding eeprom addresses, bytes, words, etc. I'm currently re-doing how I assemble data for writing into the eeprom addresses and being more thoughtful regarding how I assign addresses to 'tracks', and...

    External eeprom read/write problem

    Hi guys, thanks for your prompt replies! I'm very new to eeprom stuff and have just scaled up some basic trials I did which seemed to work ok... but maybe those early successes were only the result of ignorance disguised by dumb luck! HIPPY: In my early fumbling attempts with eeproms I seemed...

    External eeprom read/write problem

    I'm blundering my way through writing data to a 24LC256 eeprom then retrieving the data but finding I have corruption issues. The data is currently sampled by a 20M2 from two sources and written in real time into the eeprom as two 'tracks' of data. Track 1 data (used to control a servo motor)...

    AXE027 drivers installed etc. but "can't find hardware"

    A couple of days ago my trusty laptop died while I was using the Picaxe Editor. Looks like it was a power system thing... the laptop just went dead. I've transferred all my files to an external drive and for now am using that on an older PC running Windows 7. I've downloaded what seems to be...

    Serial data problem

    I'm intending to eventually use a 14M2 chip to poll several switches (and possibly a potentiometer) and output a qualifier and value to show when each switch is pressed or not, sending the data down a serial line to several 'receiver' 14M2 chips. For the moment I'm getting my head around it by...

    Flickering issue with darlington-buffered pwm output

    I am building a small lighting controller/fader system for a friend's miniature model theatre, using the adc on 10 x 08m2 chips to read 10 'channel' slider pot faders and outputting/buffering the pwm from each pic through two paralleled darlington pair inputs (ULN2803). The paralleled outputs...

    Displaying ADC output on LCD problem

    Hi, am very new to this but... I am trying to display the position of a 10k slider pot (between the 0 and 5v rails) by storing the 08M2 ADC value as a variable then feeding that value to a serial input AXE033 display. Eventually I hope to feed that ADC level down a serial bus to several 'slave'...
