P.synchZoneStart() not working properly #22

Closed sankaramp closed 6 years ago

sankaramp commented 6 years ago

hello, i made a display with 16x2 (2rows and 16columns).Total 32 8x8 matrices. i wrote a code for double height display demo...Total 32 devices taken as two zones(bottom zone and Top Zone),,,in that P.synchZoneStart(); is not working properly...When data is scrolling the two zones are not in synchonization....the bottom zone is slight faster than top zone....

please give me suggestions, thanq, Sankar.

What is your matrix arrangement? What code are you running? Have you tried the example code and does that work properly?

here is code,,,plz have a look.,

switch (j)
{
  case 0: just = PA_LEFT;    break;

}

for (uint8_t i = 0; i < ARRAY_SIZE(catalog); i++)
{
  P.displayClear();
  P.setFont(0, BigFontBottom);
  P.setFont(1, BigFontUp);
  P.displayZoneText(0, "WELCOME", just, catalog[i].speed, catalog[i].pause, catalog[i].effect, catalog[i].effect);

  while (!P.getZoneStatus(0) || !P.getZoneStatus(1))
    P.displayAnimate(); // animates and returns true when an animation is completed
  P.synchZoneStart();
  delay(catalog[i].pause);
}

} } when i'm scrolling the data to left or right,the bottom zone is scrolling slight faster than upper zone...,the two zone's are not sychronized properly.....

What about the other question I asked:

What is your matrix arrangement?

Also, does the text line up if you just print the top and bottom?

sankaramp commented 6 years ago

Sorry i forgot,,my Matrix arragement

/* \def USE_FC16_HW Set to 1 to use FC16 hardware module kits. FC16 modules are similar in format to the ICStation modules but are wired differently. Modules are identified by a FC-16 designation on the PCB /

define USE_FC16_HW 1

MajicDesigns commented 6 years ago

The arrangement refers to how you have stacked up the two rows. Is it

7654 3210

Or

4567 3210

sankaramp commented 6 years ago

total 32 8x8 matrices.. The Arrangement Stacked like this,

31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

bottom 16 matrices consider as Bottom Zone & Upper 16 matrices consider as Upper Zone

MajicDesigns commented 6 years ago

The test code below run on my system keeps the two halves synchronized. What is clear when you run the animation really slowly, as per delays in this code, is that zone 0 is refreshed before zone 1, but at the end of each cycle they are aligned correctly. This effect will become more pronounced as more modules are added in each zone, as the comms/updates length are proportional to the number of modules. `

thanq for reply,

When speed is low, its working fyn,.,but when i increase the speed the same problem is arised.

my requirement is scrolling with high speed. thanq.
