The steps to create an empty PSoC 6 project and run FreeRTOS on the CM4 core.   It's easy to set up a FreeRTOS project in ModusToolbox. The simplest way is to start from one of the examples of the IDE's Application Creator. But adding FreeRTOS to a project is straightforward too. And it allows you to select the newest version. In my case 10.3.   Start an empty project File > New > ModusToolbox Application Select the PSoC empty project for your board: I use the WiFi BT p ...
I will admit it.  I am sometimes lazy.  And forgetful.  And despite my preference for working at the Linux command line rather than a GUI, I don't really like to type any more than I need to.  It is good to know these things about oneself.  It has also lead me to create and discover some tips and tricks to use in a Ubuntu bash command shell to help my productivity.  Keep in mind the hacks below all require edits to the user .bashrc file (~/.bashrc) and are known to ...
  The USRP B205mini-i is a flexible and compact platform that is ideal for both hobbyist and OEM applications. It is designed by Ettus Research™ and provides a wide frequency range (70 MHz to 6 GHz) and a user-programmable, industrial-grade Xilinx Spartan-6 XC6SLX150 FPGA. The RF front end uses the Analog Devices AD9364 RFIC transceiver with 56 MHz of instantaneous bandwidth. The board is bus-powered by a high-speed USB 3.0 connection for streaming data to the host computer. The USRP ...

(Image Credit: University of Sussex)   For the first time, physicists at the University of Sussex have produced the world's tiniest microchips can be created from graphene and 2D materials. This is achieved by using a type of nano-origami, which the researchers presented in a paper published in the ACS Nano journal.   By producing kinks in the graphe ...
When you're making a low power design, it's interesting to know the energy use of your gizmo. In this 2nd post of the series, I measure the current in the different power modes. image source: readme file of the PSoC 6 MCU: Switching Between Power Modes example project   The PSoC6 has several sleep modes. Depending on the one that's active, parts of the controller are switched off: The example project Switching_Power_Modes (source code) demonstrates the modes. When you load this exam ...
When you're making a low power design, it's interesting to know the energy use of your gizmo. I'm working on PSoC6 projects, and I'm going to calculate its energy profile. I'll need to measure the current used by the SoC, and that requires a mod of the proto kit.   The PSoC6 has several sleep modes. Depending on the one that's active, parts of the controller are switched off: Normal state Low Power mode Low Power state Ultra Low Power mode MCU Active CPU Active MCU Sleep CPU Sl ...
By default, projects in a workspace in the Cypress ModusToolbox IDE (mtb) share board and device configuration files. There are several good reasons to do this, but it's not always what you need. If you want to build designs with a different configuration, there are a few options. The two easy ones are: multiple workspaces and - what I test here - a project with fully contained configurations.   The procedure is explained in the ModusToolbox User Guide, 5.4 Modifying the BSP Configura ...
Bluetooth Workshops: BG22 Project SeriesJoin the workshop on the 3rd Tuesday of every month "Learn new ways to integrate Bluetooth connectivity into your next project with the help of Silicon Labs expert engineers. Each project session will explore and solve challenges developers often face when building new Bluetooth designs. These solutions will be demonstrated using Silicon Labs ultra-low-power and secure EFR32BG22 Bluetooth 5.2 SoC. Attendees will have access to live Q&A and 1:1 support ...
Qumiao Si and Emilian Nica may not have come up with a new theory had the 2017 model of orbital-selective superconductivity been named differently. (Image Credit: Jeff Fitlow/Rice University)   Physicists Qumiao Si and Emilian Nica may not have come up with a new theory had their 2017 model of orbital-selective superconductivity been named differently. The new theory could explain how unconventional superconductivity arises in a diverse set of compounds. They argue that superconductivity i ...
