AVR again
2026., március 4.
A nagyon jó emlékek miatt és hogy megvan még a leszerelt működőképes hardver is, újra elővettem az új gépen az öreg AVR (Alf and Vegard’s RISC processor) nyaralóvezérlő projektemet.
Első lépésként most megnéztem, hogy ARM alapon is megvannak-e a fejlesztéshez szükséges komponensek:

Egyből nem lett még teljesen tökéletes, de mindenképpen bíztató az, hogy le akar fordulni és, ha kiszedem a problémás sort, akkor már rendben lefordul és fel is töltődik. Ezen a ponton mást még nem is kell tudnia.
Így itt egyelőre kicsit megtorpanok, mert erről a pontról már ugyanúgy az AI-val szeretnék továbbmenni most majdnem teljesen az elejéről, hogy lássam itt mit tud majd segíteni?!
A terv a következő:
- először az LCD kezelést és a hozzá kapcsolódó effekteket csinálom meg vele
- majd a modem kezelést nézzük meg együtt
- az IC2-s eeprom és hőmérséklet kezeléssel nem volt semmi gond, ott nincs új ötlet, amit meg kellene csinálni
- majd extraként a nálam maradt mozgásérzékelő tesztelésével zárjuk majd ezt a témát!
Ennek a történetnek a folytatása következik majd valamikor…
