Of course, for the establishment of this channel connection is a certain condition, that is, the Bluetooth set up to be able to connect the at mode0x0:softwareserial LibraryThe existing Arduino hardware supports pin 0 and 1 (connected to the computer via USB) for serial communication. The serial is carried out via a hardware called UART (chip built-in). This hardware allow

Pcduino Fingerprint access Control development – Chapter II

The configuration of an article was told. Let's talk about the text below.began to take zfm-206 fingerprint surgery.Let's start by introducing two types of zfm-206. One is USB type. The other is the UART. In view of individual needs, the UART goes up.Since the intention is to use the UART on the Pcduino to do fingerprint access to the application, it is natural t

Hosttestapp in the CDC class USB program extracted, to achieve dongle and PC data communication, does not involve Ble-stack protocol stack related just a USB program. 4) because the CDC class of USB relatively simple, the host computer programming can use the serial port, in 3) on the basis of the implementation of HID, specifically about this part of the USB drive and the host computer is not very clear thinking.4, need to do things:1) Use the purchased CC2540 verification link to establish th

How Freescale ATK (advanced toolkit) Works

Freescale ATK (advanced toolkit) is an embedded system flash burning software designed for its MX series CPU core. It can be used to burn Bootloader and kernel to flash. (Nor, Nand, MC/SD ...). The principle and workflow are as follows: First, set the jumper to UART/USB boot. Then, after the Board is powered on, the ROM in the SOC starts to initialize the internal RAM and waits for data on the UART/USB

Design of universal USB Interface Module Based on AVR Microcontroller

The 8KB boot loader is called BL1.③BL1:BL1 can initialize system clock, UART, and SDRAM for user. After initializing, BL1 would load remaining boot loader which is called BL2 on the SDRAM④finally, jump to start a
