What’s I2C I2C is a serial protocol used for a two-wire interface to connect low-speed devices such as microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces, and other similar peripherals in embedded systems. It is synchronous, multi-master, multi-slave, packet switching, single-ended, serial communication bus invented by Philips Semiconductors (now NXP Semiconductors) in 1982. I²C only …
Recently, one customer has a requirement about the CSR USB-SPI programmer for development purposes. At first, they found a programmer with an RS232 port which is not supported by the Feasycom’s CSR module. Feasycom has a CSR USB-SPI programmer with a 6-pin port (CSB, MOSI, MISO, CLK, 3V3, GND), with these 6 pins connected to …

What’s Arduino? Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. The Arduino …
As we know, in the context of the Internet of Things, the acquisition and application of location information are becoming more and more important. Compared with outdoor positioning, the working environment of indoor positioning is more complex and delicate, and its technology is more diverse. For example, smart factory personnel and cargo management and scheduling, …
What is Bluetooth Mesh? Bluetooth Mesh is a computer mesh networking standard based on Bluetooth Low Energy that allows for many-to-many communication over Bluetooth radio. What’s the relation and difference between BLE and Mesh? Bluetooth Mesh is not a wireless communication technology, but a network technology. Bluetooth Mesh networks rely on Bluetooth Low Energy, it’s an …
Now indoor positioning solutions are no longer purely for positioning. They have begun to integrate data analysis, human flow monitoring, and personnel supervision. Feasycom technology provides the Beacon solution for these usage scenarios. Let’s take a look at the three location-based functions provided by the BLE beacon: big data analysis, indoor navigation, and personnel supervision. 1. …
As we know, IEEE 802.11 a/b/g/n is the set of 802.11 a, 802.11 b, 802.11 g, 802.11 n, etc. these different wireless protocols are all evolved from 802.11 to implement wireless local area network (WLAN) Wi-Fi computer communication in various frequencies, here is the difference between these profiles: IEEE 802.11 a: High speed WLAN profile, …
