daming spare ah Grin

madali lang naman gamitin yang BTSerial1 from sir zero UART lang ang katapat

hehe. mahirap na kasi baka magkamali at masira yung isang BT at least may pamalit...hehe. nga po pala 3.3volts kasi yung required for BT Module... what if nalagyan ko yun ng 3.6v sira na ba agad yun kahit 0.3v lang yung lagpas? yung BT ni sir zero hindi ko pa ginagalaw.hehehe. nag-iisa kasi eh. mutyang mutya tuloy. pero baka this weekend try ko na interface sa 16f877a yung kay sir zero.hehe

sana nga po ma-interface agad sya sa MCU or kahit sa pic lang. sana din di mahirap yung source code nya..

Wala ka na gagawin kungdi ikabit sa. Use PIC16f628 para 3.3v lang kailangan mo supply pati sa PIC

no initialization needed, unlike nung EGBT kailangan pa magsend ng data sa BT Mod bago magamit... nga po pala 3.3v lang po talaga pwede? what it 3.4-3.6 yung pumasok na voltage sa BT Mod masisira na po ba agad yun?

up till 3.6V cguro wag lang tatagal. I make use of a 3.3V regulator both for the MCU and the BT module para isang regulator lang.
