minsis at-mega 128

Assalaamuálaikum warohmatullah wabarokaatuh

Ati kulo bingah sanget naliko nyerat seratan puniko. amargi  minimum sistem at-mega 128 (minsys atmega 128) ingkang kulo damel kaangsalan hasil, sak mantunipun kulo ndesain, ngecing lajeng kulo soder, naliko diprogram purun mlampah. wiwitane enten masalah dateng fusebit ipun, nanging kelawan kesabaran akhiripun saget kulo dandosi lan kepanggih masalahipun.

meniko kulo sukani ngertos desain PCB kulo.

lumayan sae to nggih? rencang rencang kulo kathah ingkang remen kalean deasin kulo, akhire tumut ngecing

:D minsys atmega 128 kulo

lha meniko skemanipun

semanten rumiyin seratan  minsys atmega 128 saking kulo, matur nuwun, mugio saget dados pangangen angen kito sedoyo.
nuwun.

Assalaamu'alaikum Wr.Wb.
