MegaLoad U | Beta tester needed

admin    All projects     AVR Bootloader

I just finish a new version of MegaLoad,  It's name is MegaLoad U  for Universal.  You will be able to use old and future devices without upgrading MegaLoad U.  It not compatible with the old bootloader files.  You need the bootloader that came with MegaLoad U.  It's a first release so please be cool with me!  So I'm waiting for your beta testing…

New bootloader C and S file release on the 20/07/10  Please comment

  admin,
  has only one error
  # ifdef INTVECREG
  MCUCR = (1 <<IVCE); no error  here," IVCE symbol is not defined."
  MCUCR = 0×00;
  # endif

  I have a doubt in the above function, the Bit IVCE was moved to left for MCUCR. after this, load 0×00 to  MCUCR. . this is correct?  which options below should set MCUCR
   
  Table 35. Interrupt 0 Sense Control
  ISC01 ISC00           Description
  0          0                    The low level of INT0 generates an interrupt request.
  0           1                    Any logical change on INT0 generates an interrupt request.
  1           0                   The falling edge of INT0 generates an interrupt request.
  1           1                    The rising edge of INT0 generates an interrupt request

  What is your MCU,  The interupt level is not the good thing, it's there to set the interupt vercor

  Bonjour,
  Cela fonctionne-t-il avec une liaison 1 wire ?

  Hi admin, I wonder what does the NSHIFTPAGE do??
  Why need to shift this?
  I'm using atmega8, facing problem on placing the data block into correct address

  Check in the datasheet it’s how many byte you must shift to address the corect page address, I’m not sure but in megaload there is a exemple of what to do

  @NC: Look at the datasheet of atmega8, Figure 103 on page 215, you will see how  page address and word address of one page. And Table 84 on page 221 show bit corresponding in Z-register. Page address is 7bits (in the Z-register its Z12:Z6) – so that you must shift by 6 (NSHIFTPAGE) from RealPageAddress
