Tsis ntev los no kuv tau txais qee cov ATMEGA8L chips uas tsis tuaj yeem nyeem lossis tsis tsim kho los ntawm USBASP. Kuv tau xav tsis thoob tias cov chips no siv tau lossis tawg tag.
Kuv tau nyeem cov ntawv teev npe ntawm cov nti thiab pom tau tias lub nti yuav tsis tuaj yeem nyeem yog tias nws tau xauv thiab/lossis lub fuse teeb tsa tsis raug.
Nws kuj tau hais tias High Voltage Parallel Programming (HVPP) tuaj yeem siv los cawm lub nti. Yog li kuv tsim qhov no los sim nws.
Koj tuaj yeem ua ib qho los cawm koj cov chips ib yam.
Kauj ruam 1: Tsim Circuit Court
Koj xav tau cov khoom hauv qab no:
1. Ib qho haujlwm ATMEGA micro controller (ATMEGA8/88/168/328, Kuv tau siv ATMEGA168PA board)
2. Ib 28 tus pin DIP lub qhov (socket) rau lub hom phiaj nti (Koj tuaj yeem siv ZIP lub qhov rooj yog tias koj muaj)
3. Ib qho NPN transistor (2N3904 lossis 2N2222 thiab lwm yam, Kuv tau siv 2N3904 ntawm no)
4. Ob 1K resistor
5. Ib qho 150R resistor (Txhawm rau txwv tam sim no rau LED liab, koj xav tau 100R rau ntsuab lossis xiav LED)
6. Ib qho LED rau +12V qhov taw qhia (Kuv tau siv LED liab)
7. Lub roj teeb 12V (A23) lossis tus lej nce qib (Kuv tau siv MT3608 cov theem teeb tsa hauv qhov haujlwm no)
Muab lawv tag nrho ua ke raws li Schematic.
Kauj Ruam 2: Program Configurator Micro Controller
Thauj cov cai hauv Arduino IDE, xaiv koj lub rooj tsavxwm thiab hloov kho lub nti.
Lossis koj tuaj yeem tsim kho lub nti ncaj qha los ntawm kev siv kuv cov ntaub ntawv ua ntej ua ke HEX.
Kauj Ruam 3: Txhim Kho Qhov Teeb Meem Chip
Tam sim no, txhua yam tau npaj txhij. Nws yog lub sijhawm los kho qhov teeb meem nti.
Koj tuaj yeem siv cov lus txib los ntawm Serial Monitor hauv Arduino IDE (BAUD 57600) txhawm rau teeb tsa lub nti. Cov ntawv qhia tag nrho tuaj yeem pom sab hauv Arduino qhov chaws.
Xwb, koj tuaj yeem siv lub qhov rais GUI los sib tham nrog tus teeb tsa. GUI tau suav nrog txhua txoj haujlwm uas tus tsim teeb tsa muab.
Koj tuaj yeem rub tawm cov ntawv ua tiav lossis cov cai los ntawm kuv github thiab suav nws tus kheej.
Kauj Ruam 4: Cov Lus Kawg
Kuv tau ua tiav cawm cov nti uas nyeem tsis tau thiab lawv txhua tus ua haujlwm tau zoo tom qab kuv tau lwv cov nti thiab rov pib dua qhov teeb tsa.
Koj tuaj yeem kho koj cov teeb meem chips ib yam.
Txhawm rau kom tau txais cov ntaub ntawv ntau ntxiv thiab cov peev txheej tag nrho rau txoj haujlwm, thov mus ntsib kuv tus github.
