Consigli e considerazioni su sviuppo python per raspberry PI

(by Ivan Tarozzi - 10/06/2021)

Prendendo spunto da uno scambio di messaggi telegram sul gruppo FabLab Romagna (SMD 2023) e nella speranza che possa essere utile a chiunque voglia cimentarsi nella programmazione python su raspberryPI (o anche solo a chi voglia testare programmi python presi su git**b), riporto alcune indicazioni e considerazioni sull'esperienza appena conclusa e su modi alternativi di affrontare il problema.

Premetto che non sono un super-esperto di python e che le considerazioni che scriverò sono personali e perfettamente opinabili. Sono frutto della mia esperienza, ma non è detto che siano valide per tutti e che non possano essere smentite (anzi, chiunque legga e voglia apportare critiche costruttive o contributi diversi ben venga).

Caso di studio
