    Multiplexing with SN74LS47N

    Hi. You are right, one digit is slightly dimmer than the other. When I download your code, the counting start, but when it reach 99, it start to show some other characters. One digit shows the symbol for 10-15, from the above table. Guess we have to insert an ifstatement? - nerdegutta

    Difference in speed: LinAXEPad vs Logicator PICAXE 6.0.7.5

    When I click Open or File->Open in LinAXEpad, the program terminates. That's happening wether I'm a user or sudo. Frustrating. Attached is dmesg | tail > error.txt Got some general protection error in libpixman... Oh, well... I'll deal with it later. However, the virtual win7 works fine. -...

    Difference in speed: LinAXEPad vs Logicator PICAXE 6.0.7.5

    Hi. I've noticed something strange. My setup is as follows: Ubuntu 14.04 32-bit LinAXEpad RevEds USB - Serial converter This works kind of OK. But I have to runLinAXEpad as root, or I won't get access to the serial port. I tried almost everything. I'm OK with that. On this Ubuntu PC, I've...

    Multiplexing with SN74LS47N

    Hi. I'm trying to learn how to multiplex a 2-digit 7 segment display. Do anyone have any links or, tutorials on this? This is my schematic, it's on a breadboard - for now... This is my code: #no_data symbol lDelay = 200 symbol digit1 = c.0 symbol digit2 = c.1 let dirsb = %111111 main...

    HI2CSetup and 24LC512

    I've read the manual, but I haven't found any place this is described. The Setup command is: HI2CSetup I2CMaster, %1010dddx, I2SFast, I2CWord When A2, A1 and A0 is grounded on the PCB. What should the ddd look like? - nerdegutta

    Retrieving data from EEPROM

    I think there is some strange things with the SaveTo24LC16B procedure: SaveTo24LC16B: If MemPos > $7FF Then EpromFull ' if MemPos is bigger than 2048 then eeprom is full deviceID = Mempos / 256 * 2 | $A0 ' configuring the deviceID HI2CSetup I2CMASTER, deviceID, I2CSlow, I2Cbyte '...

    Retrieving data from EEPROM

    With reference to this thread: http://www.picaxeforum.co.uk/showthread.php?24517-Oh-no-not-another-GPS-logger The logger is set to save data every 7 sec. I haven't bothered to save the date from the GPS, but I save lat, lon, hour and minute. I was wondering why the time is not saved in the...

    Oh no - not another GPS logger

    Hi, so I've made a GPS logger. Everything seems to work fine, but when I read the data back from the 24LC16b EEPROM, something strange is happening. It looks like the EEPROM address has moved one place too far. I've not seen any pattern. Sometime all data is read back perfect, and other times...

    24LC16b EEPROM explanation, please

    Hi. Can someone please explain to me how to use the 24LC16b EEPROM? I need to store 18 bytes as many times as I can. If I understand correctly: Block 000 can store 256 bytes Block 001 can store 256 bytes Block 010 can store 256 bytes Block 100 can store 256 bytes Block 111 can store 256...

    Erase 24LC16B eeprom

    Hi. What is the fastest way to erase the 24LC16B EEPROM? I've tried to overwrite with zeroes, but it takes really long time. - nerdegutta

    serin with 08m2 and 14m2

    Hi. Is there any difference in 14m2's B.1 and 08m2's C.1 when working with serin? Shouldn't I be able to change IC and change from B.1 to C.1? When 14m2 is in breadboard, it works. Changing to 08m2 and C.1, it's not working. To me, that is very strange.... - nerdegutta
