The STM32 H7-series is a group of high performance STM32 microcontrollers based on the ARM Cortex-M7F core with double-precision floating point unit and optional second Cortex-M4F core with single-precision floating point. Cortex-M7F core can reach working frequency up to 600 MHz, while Cortex-M4F - up to 240 MHz.
At the destination, a second UART re-assembles the bits into complete bytes. Each UART contains a shift register, which is the fundamental method of conversion between serial and parallel forms. Serial transmission of digital information (bits) through a single wire or other medium is less costly than parallel transmission through multiple wires.
In computing, bus mastering is a feature supported by many bus architectures that enables a device connected to the bus to initiate direct memory access (DMA) transactions. It is also referred to as first-party DMA , in contrast with third-party DMA where a system DMA controller actually does the transfer.
The ARM Cortex-M family are ARM microprocessor cores that are designed for use in microcontrollers, ASICs, ASSPs, FPGAs, and SoCs.Cortex-M cores are commonly used as dedicated microcontroller chips, but also are "hidden" inside of SoC chips as power management controllers, I/O controllers, system controllers, touch screen controllers, smart battery controllers, and sensor controllers.
Arduino RS232 Serial board - a predecessor with an ATmega8. The Arduino project started at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy.At that time, the students used a BASIC Stamp microcontroller, at a cost that was a considerable expense for many students.
Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
The USB 3.2 specification [7] added a second lane to the Enhanced SuperSpeed System besides other enhancements so that the SuperSpeedPlus USB system part implements the Gen 1×2, Gen 2×1, and Gen 2×2 operation modes. However, the SuperSpeed USB part of the system still implements the one-lane Gen 1×1 operation mode.
Following in the tradition of its two predecessors, the second edition (2006) features a dragon and a knight on its cover, and is informally known as the purple dragon. Monica S. Lam of Stanford University became a co-author with this edition. The second edition includes several additional topics, including: Directed translation; New data flow ...
