AVR Serial Download Cable
Ntau tus phooj ywg tau ntsib thaum qhov chaw nres nkoj sib luag puas lawm. Lub sijhawm no, qhov chaw nres nkoj sib txuas rub tawm cable tsis muaj txiaj ntsig. Qhov tseeb, rau cov khoos phis tawj desktop, feem ntau ntawm lawv yog tshwm sim los ntawm kev xau ntawm lub me me capacitor los ntawm qhov sib npaug ntawm qhov chaw nres nkoj tus pin mus rau hauv av. Tsuas yog tshem nws ncaj qha. Ntawm chav kawm, serial-parallel nti ntawm lub motherboard kuj puas.
Lub USB interface download cable yog teeb meem heev los ua. Ntawm no yog serial AVR download cable, uas kuj yog ib qho yooj yim mus use thiab muaj ceev ceev. Lub hauv paus code raug kuaj kom raug.
AVR STUDIO rau software
Fuse ntsis kev teeb tsa FUSE: L=BF, H=C9
Lub BOD tau qhib thiab teem rau 2.7V los tiv thaiv EEPROM kev puas tsuaj. Nws yog teem rau 2.7V hloov mus rau 3.3V lossis 5V fais fab mov. Siv MAX3232 rau 3.3V fais fab mov.
Firmware: ourdev_432579.rar
Cov lus qhia:
Tom qab tag nrho cov khoom tau teeb tsa, tig qhov chaw hloov mus rau "tus kheej-programming" txoj hauj lwm, txuas nrog rau qhov chaw nres nkoj sib txuas programmer, thiab tom qab ntawd tig qhov chaw hloov mus rau "ua haujlwm" txoj haujlwm tom qab programming.
Txuas lub serial chaw nres nkoj cable, qhib AVR STUDIO software, nyem qhov txuas programmer thiab xaiv "STK500 LOSSIS AVRISP" los txuas.
Lus Cim:
Siv MAX3232 thiab MEGA16L-8, lub hwj huam mov tuaj yeem yog 3.3V-5V;
Nrog MAX232A thiab MEGA16L-8, lub zog hluav taws xob tsuas tuaj yeem siv 5V.
Lub peripheral capacitor ntawm MAX3232 thiab MAX232A tuaj yeem siv 104, thiab peripheral capacitor ntawm MAX232 tuaj yeem siv 105 (1UF).
