SPI Isolation Board

The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usually. It is based on Linear’s LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and signal traces and components at the top layer. Signals and power are supplied over standard 100mil (2.54mm) pitch IDC header. Specification Dimension: 40.005 mm x ...

ulibSD – a library for use SD cards in SPI mode with uControllers

ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely writtenin C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size, remember this. Public methods ulibSD has four public methods: SD_Init: Initialization the SD card. SD_ ...

Using BMP180 for temperature, pressure and altitude measurements

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup Bosch Sensortag’s BMP180 ...

Using Efficient SPI Peripherals for Low-Cost MCU-Based IoT Designs

Efficient Internet of Things (IoT) designs must balance a host of requirements that often work against each other. Low cost is important, but often supporting all the key features required by the application increases MCU pin count and memory size—two things that work against low cost. Low power is also important for IoT applications where battery operation is a must. Adding features and improving performan ...

1Mbit SPI FRAM comes in chip-scale packaging

The 1Mbit SPI FRAM is in an 8-pin wafer level chip scale package (WL-CSP) which is an additional package variant to the existing product MB85RS1MT. In comparison to the industry standard SOP-8 package, the new WL-CSP package, which measures 3.09 x 2.28 x 0.33 mm, reduces the surface mounting area by 77%, and the device height by 80%. The WL-CSP package makes FRAM a non-volatile memory solution for wearable ...

Using an Arduino to Control or Test an SPI electronic device

There are many electronic devices that use the SPI  bus, or Serial Peripheral Interface bus, for communications (e.g. various sensors, LCD displays, digital potentiometers, D/A and A/D converters, wireless transmitters and receivers, audio volume controls).  The devices receive data serially from a microcontroller using a 3-wire set-up that includes a chip select signal (usually titled CS - when this signal ...
