sirs,

may mga problem ako regarding dito..

simple counter lang naman po siya.. kaso iba ung output na nangyayari sa expected ko..

dun sa schematic above..

1st press ng button: eto ang output <number 1> // no space dapat
2nd press: <number2> // tama ung output
3rd press: <number 3> // may space na naman
4th press: <number4> // tama ulit ung output
5th press: <numerd5> // may d na lumabas between r and 5
6th press: <number6> // tama ulit ung output
7th press: <number...> // lumalabas na ung initial display ko
8th press and so on.. // nagshishift po ung initial display ko gada press nung button.. ung number lang po ung maayos na display.. ung mga sunod.. nagshishift na lang..

tapos everytime na magbubuild ako.. may warning na ganito..

illegal conversion of integer to pointer

pakiramdam ko.. sa lcd_display_num() function nagmumula ang problem.. hmm..

thanks in advance po..

['yus]

no need na ata dun sa line na "lcd_puts(num);"
para saan sana yan? baka pwedeng i-delete na lang.

[carlsfootprints]

ang gwapo mo ate yus.. hehe..

solve na agad..

[carlsfootprints]

ate yus,

follow-up question lng.. ung size nung char array na dineclare ko, kahit ano, oks lang naman.. ano pong relevance nun?

tapos, pwede ko po bang gamitin ung sprintf kahit strings na ung ididisplay ko? nagtatry ako kaso failed..

['yus]

yung size ng "s" array mo dapat equal(or mas malaki) sa length ng string na idi-display mo.

yung unang size na ginamit mo, w/c is "1", is gumana kasi single digit pa lang ang dini-display mo.

[carlsfootprints]

ahh.. ok.. tnx ulit..

[carlsfootprints]

dapat pla int pa rin ang declaration ko kahit char string ang ididisplay...

working na..

next, eeprom..
