[High-speed bus] Introduction to JESD204B

1. Introduction JESD204 is a high-speed serial interface connecting data converters (ADCs and DACs) and logic devices, supporting serial data rates up to 12.5 Gbps and ensuring repeatable deterministic latency for JESD204 links. As high-speed ADCs enter the GSPS range, the preferred interface protocol for data transfer to FPGAs (custom ASICs) is JESD204B. The JESD204B standard is a layered specifi... »

Storage system in ARM architecture

Embedded systems based on the ARM core may include various types of memory such as Flash, ROM, SRAM, SDRAM, etc. Different types of memory have different access speeds and data widths. The following mainly describes it from three aspects: address space, memory format and memory aligned access. 1.Address spaceThe ARM architecture treats memory as a linear combination of bytes starting at address ze... »

How to use the esp8266 module (detailed explanation) essential for getting started

1.Structure of esp01 2.Use of wifi This time we useESP-01S, in the design, in addition to ESP01S, there is also ESP-01. The main difference between the two is,connection part of circuit, ESP-01S has a pull-up resistor internally, so in actual use,The enable terminal of EN does not need to be connected.Generally, you only need to connect 4 wires (VCC Ground tx RE).andWhen ESP-01 is in use, it requi... »

Summary of IIC communication protocol (detailed description of the complete process)

Introduction to IIC protocol The IIC (inter-integrated Circuit integrated circuit bus) bus supports short-distance communication between devices and is used for the interface between the processor and some peripheral devices. It requires two signal lines to complete the exchange of information. A special process advantage of IIC is that the microcontroller only requires two general-purpose I/O pin... »
