Digital Camera Interface The DCMI (Digital Camera Interface) is a synchronous parallel interface designed to receive a high-speed data stream from an external CMOS camera module. It offers compatibility with 8-bit, 10-bit, 12-bit, or 14-bit camera modules.  The DCMI peripheral supports Embedded Line and Frame synchronization methods in addition to the Hardware Synchronisation from the CMOS Camera Module. It has two operating mode, namely Continuous or Snapshot mode. Additionally, it offers a crop feature and supports various data formats, including 8/10/12/14-bit progressive video (Monochrome or Raw Bayer), YCbCr 4:2:2 Progressive Video, RGB 565 Progressive Video, and Compressed Data in JPEG format.   For more information on the DCMI peripheral, read the Training material for DCMI on STM32L4 from STMicroelectronics . DCMI Registers The DCMI peripheral has Control and Status registers for the DCMI Core and Interrupts. It also has a few registers for handling Data synchronization, Croppi

Cifradopro: A baremetal Hardware Security Module using the STM32L4S5 Cortex-M4 MCU

Image
What is CifradoPro? Cifradopro is a baremetal Hardware Security Module based on the STM32L4S5ZI microcontroller. It is capable of generating Random Keys in various sizes, Encrypting plaintext, and Decrypting ciphertext using the Advanced Encryption Standard. Additionally, it can create One-Time Pads of different lengths and generate a Hash of input data using the Secure Hashing Algorithm. The module can store the generated cryptographic keys in an external memory device. As a safeguard against physical tampering, the device is designed to erase the contents of the external memory if the enclosure is breached. The device leverages the Random Number Generator , AES Hardware Accelerator , and HASH Processor of the STM32L4S5ZI for cryptographic operations. It employs the built-in UART peripheral for device control via a serial terminal application such as PuTTY. The external memory, a  256kBit EEPROM from Microchip , is interfaced using the STM32L4's onboard I2C Peripheral. A GPIO pin

SignGlove: Bridging the Communication Gap for Paralyzed Patients

Image
SignGlove What is SignGlove ??? SignGlove is an innovative wearable glove designed to bridge the communication gap for paralyzed patients, enabling them to express their wants and needs through hand signals. It enables caretakers to understand and respond to the needs of individuals with limited mobility.  Over a Wi-Fi network, SignGlove allows users to transmit their hand signals directly to a caregiver's device. One of the key features of SignGlove is its configurability, which allows it to adapt to each user's unique abilities and hand gestures. By customizing the device to match the specific range of motions and signals that a user can comfortably make, SignGlove ensures a highly personalized and tailored communication experience.  With SignGlove, paralyzed patients no longer rely solely on non-verbal cues or guesswork to convey their needs. The SignGlove concept ...... The concept of SignGlove was inspired by the work of Navid Azodi and Thomas Pryor from the Univer
