Mirror and Don't mirror - problem

[Kama]

Hi,

Why at mirror inclusion to the programmed image the shone strip is added? Look the attached screenshot. At normal inclusion (not mirror) everything is all right. How to get rid of it?

Regards

[Kama]

Nobody knows? What can be? In pictures of users the same problem - look. On the mirror party there is a parasitic luminescence of LEDs.

hmm, thats a bug we havent heard of before. does it move if you change the magnet position?

[Kama]

Position of a magnet does not correct a question. If the image is located on all area - then this luminescence is not visible. If the image is located not on all area - then there is a parasitic luminescence

There already was solution for this bug on forum, cant find it now. That "line" is last line of previous image or first of next image cant tell for shure =]

But You must change this (in main.c):

Code: Select all

  if (sensor_timer < ((F_CPU/NUM_PIXELS)/256 * STANDBY_TIMEOUT)) {   
    // less than ~5 seconds since last sensor
    PORTA |= 0x1;
    eepromaddr %= NUM_PIXELS * 4;
    spieeprom_read_into_leds(eepromaddr + anim_eeprom_offset, FRONT);
    if (mirror) {
      spieeprom_read_into_leds(anim_eeprom_offset + (1024UL-eepromaddr), BACK);
    } else {
      LATCH_SELECT_PORT |= _BV(BACK);
      NOP; NOP; NOP; NOP;
      LATCH_SELECT_PORT &= ~_BV(BACK);
    }

to this:

Code: Select all

  if (sensor_timer < ((F_CPU/NUM_PIXELS)/256 * STANDBY_TIMEOUT)) {   
    // less than ~5 seconds since last sensor
    PORTA |= 0x1;
    eepromaddr %= NUM_PIXELS * 4;
    spieeprom_read_into_leds(eepromaddr + anim_eeprom_offset, FRONT);
    if (mirror) {
      spieeprom_read_into_leds(anim_eeprom_offset + (1024UL-eepromaddr)-4, BACK);
    } else {
      LATCH_SELECT_PORT |= _BV(BACK);
      NOP; NOP; NOP; NOP;
      LATCH_SELECT_PORT &= ~_BV(BACK);
    }

Thanks. I will try.

Only I have not understood - how to make these changes? Where to make changes? The special program is necessary? Help, please

Personaly i am using AVR Studio, but the easiest way i think, is to download firmware, there will be source files, make file and hex file. edit the main.c in notepad (add "-4"), save and compile it with the make file, search site for tutorial using make files. Then upload new hex to spokepov.

[Kama]

Thanks. If I make changes - all will earn normally? And not the mirror party also will be normal to work?
P.S. How with you to communicate? I have a question concerning your project on a site http://kaspars.id.lv (a lantern for a bicycle). My server gives out an error at letter sending My address kama95@rambler.ru
P.P.S. Do you speak in Russian?

[matajumotors]

If you will change that, everything will work as it should. =] Da, ja govorju po russki =] mail is working.

Hi

May I know how to upload the new firmware into Spokepov with USBtiny?
