Android Studio - RC Bluetooth Araba Projesi

Serinin son videosuna hoşgeldiniz. Bu videomda daha önceki videolarda anlatmış olduklarımı uygulayacağımız RC arabayı gerçekleştiriyoruz. Kit olarak 2WD Robot araba kitini kullandık.
İyi seyirler dilerim.

STM32F103C8T6 16x2 LCD HAL Kütüphanesi

Herkese merhaba,

Youtube'da başlatmış olduğum CubeMX ile STM32F103 programlama serisinde kullandığım LCD HAL kütüphanesini burada paylaşıyorum.

Öncelikle kütüphanenin orijinalinin bulunduğu blog sayfasının linkini paylaşmak istiyorum.
