  1. Re: Another attempt for I2C eeprom, this time - 25C256.

    Thanks a lot !
    At my system, that menu bar was not visible at all
    and in file/edit menu, they have no such setting...
  2. Re: Another attempt for I2C eeprom, this time - 25C256.

    I don't see any mode selector in GLCD font creator from their website.
  3. Re: Another attempt for I2C eeprom, this time - 25C256.

    Not exact match, but HxD hex editor does the job almost in the way I see it.
  4. Re: Another attempt for I2C eeprom, this time - 25C256.

    Yes I know all these :)
    The issue with Mikroe "creation" is it, as everything else done by them, is written with left feet- need admin priviledges to run it, and it outputs fonts rotated by 90...
  5. Re: Any physically large, 64 pin PIC16 or PIC18 chips available?

    Thanks, I need IC for direct PCB mounting.
    So have to split tasks between two TQFP-44 chips then...
  6. Any physically large, 64 pin PIC16 or PIC18 chips available?

    Hello.
    Atmega's are available in 14x14mm 64 TQFP packaging, that is quite easy to solder, but all PIC16/18 I've found so far, in TQFP64, are in 10x10mm packaging, with very thin legs, which makes...
  7. Re: Another attempt for I2C eeprom, this time - 25C256.

    Now I need bitwise hex editor - one that allows editing hex file by bits, not by bytes. Any ideas :)
  8. Re: Another attempt for I2C eeprom, this time - 25C256.

    WOW! Finally it works!



    x var word
    y var byte
    adr var byte
    sda var portc.0
    scl var portc.1
    lcdout $fe, $01, " "
  9. Re: Another attempt for I2C eeprom, this time - 25C256.

    So what should I write instead of 160?

    I've searched this forum, and people do use plain numbers in I2C eeprom write/read?
  10. Re: Another attempt for I2C eeprom, this time - 25C256.

    So what's wrong with 160? it is chip address, A0, and isn't that fixed?

    Regarding the logic analyzer. I have that saelae thing.
    I can't get it work as I understand it should work - run...
  11. Re: Another attempt for I2C eeprom, this time - 25C256.

    Yes I made an error in tittle, chip is certainly 24C256.
  12. Re: Another attempt for I2C eeprom, this time - 25C256.

    No difference - already tried all combos like 159+160, 160+161 and so on....
  13. Another attempt for I2C eeprom, this time - 25C256.

    Hello.
    I decided to give it another try, now with this module.

    https://www.elecrow.com/i2c-eeprom-module-at24c256-p-736.html

    Pull up resistors installed, and following code configured.
    when...

    Re: Arraywrite can't write word variables?

    I'm not reading anything :)
    the above quoted 2 line code from manual gives that error.
    There is no more code in the program.

    Arraywrite can't write word variables?

    Hello.
    As PBP manual states, page 35. It is possible to write word-size variables into word size array, using arraywrite statement. There is even an example.

  17. Re: 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    I'm getting 16F887 for about 30 cents :D Ones you mentioned cost 10-20 times more

    For the I2C/SPI EEPROM I already had separate topics open with code posted, but nothing happened

    And 1 wire...
  18. Re: My code for ADC button handling, it works, but can it be slimmed down?

    ADCIN X,ADVAL
    IF ADVAL=20 then Gosub Y1
    IF ADVAL=10 then GOSUB Y2
    IF ADVAL=30 then GOSUB Y3

    and so on.
  19. Re: 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    1) Are there any PIC chips with 4KB of EEPROM available?
    2) I tried, can't make it work.
    3) Also does not work.
    4) Running on PIC16F887, code is already tight :D
    5) No open source...
  20. Re: 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    DS28EC20 has 20KB of EEPROM, and already available from Chinese vendors, for around $1 per IC :)
    I actually need 2KB for font and 256 bytes for each language text (have 8 languages so far) so even...
  21. Re: My code for ADC button handling, it works, but can it be slimmed down?

    Yes and we again will have extra "left" and "right" variables, one per each button - what I wanted to avoid :)
  22. Re: My code for ADC button handling, it works, but can it be slimmed down?

    No it does not.
    It does not do "do not repeat action until user releases and pushes key again"
  23. Re: 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    I have posted all that here already.
    And this topic is about 1wire eeprom :)
  24. Re: 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    I tried all sample codes and circuits for eeproms posted here
    none seems to work for me.
    for 1 wire device, haven't bought any yet, just deciding
    For experiments i have DS2501-U chip at hands.
  25. 1Wire serial EEPROM, DS28EC20 and similar, any experience?

    Hello.
    Unfortunately, I was not able to read or write any I2C or SPI eeproms with PBP, so as last chance, I'm now looking into 1wire devices.
    I have worked with DS18B20 and it poses no issues, but...
