The nRF52 DK board is excellent for testing and getting products with the nRF52 IC ready. It has an onboard nRF52 BLE IC which can be programmed as a beacon. It can also act as a programmer and be used… Read More »Programming a Custom nRF52 Beacon using nRF52 DK
Modbus is a data communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers(PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting… Read More »RS-485 MODBUS Serial Communication using Arduino UNO as Slave Part 2
This is a two-part article that explains the step-by-step details of interfacing USB to RS485 Converters to Communicate with Modbus Devices. The first part explains the procedure to read and transmit RS485 data from using the converter and the second… Read More »Using USB to RS485 Converters with Modbus Devices – Part 1
Touch screens are finding their way into a variety of embedded products. Most touch-enabled devices will require a calibration routine before they can be used in your product/project. All the modules that you require to implement this calibration process are… Read More »Touch Screen Display Calibration
Optical liquid level sensors are solid-state liquid level sensors, meaning they have no moving parts to cause unreliability. They use infra-red light and can be used in environments where a traditional float switch would not be suitable to detect liquid… Read More »Liquid Level Sensor Contact (Analog Output)
From part 3 of the NRF Getting started article we learned about Controlling LEDs & Reading Switch Inputs, in part 4 of the NRF series we will learn about Eddystone and how it transmits Eddystone packets. Eddystone is another… Read More »nRF52 Programming Tutorials – Part 4 Eddystone
From part 2 of the NRF Getting started article we learned about Nordic SDK, in part 3 of the NRF Getting started series we will learn about controlling LEDs and reading switch inputs.
