AT89C51 tidak bisa pakai downloader ISP, DT51 harus pakai downloader DT51 juga.
Kalau dari skema minsys DT51 ver3.3 harusnya pakai AT89S51/52 bukan AT89C51.
iya kak, ane pake AT89S51, minsys DT51 ver3.3, software nya pake DT51 jg,
kalo mau download file hex (ane pake bascom)
ke DT 51 -> address range eror
ke AT89LP ISP -> Target communication failed. make sure that your development board has power and is connected to the selected port.
gimana ya kak??
