Open Source 150M Oscilloscope Differential Probe

The PD150 is a compact 150MHz differential oscilloscope probe for engineers on a budget and advanced hobbyists. It has advanced features such as automatic DC offset voltage zeroing and low-frequency common-mode rejection tuning. It will also provide complete documentation in the spirit of old-school "anchor" test equipment, detailing its working principles in addition to typical instructions and specifications.

TI launches wireless metering bus M-BUS reference design

This reference design describes how to use TI's wireless M-Bus stack with the CC1310 and CC1350 wireless MCUs and integrate them into smart meter or data collector products. The software stack is compatible with the Open Metering System (OMS) v3.0.1 specification. EN13757-1 to EN13757-7 are European meter reading standards, including wired and wireless metering buses (M-Bus); these are very popular in ultra-low power metering and sub-metering applications. The design provides ready-to-use binary images for any wireless M-Bus S, T or C mode at 868 MHz, with unidirectional (instrumentation) or bidirectional configuration (instrumentation and datalogger). Multiple precompiled binary images are provided covering metering applications including but not limited to heat cost allocators (HCA), gas, water and heat meters, or electronic meters with external host MCUs.
