In the ever-evolving world of electronics and embedded systems, accuracy and precision are non-negotiable qualities. These qualities are particularly critical when it comes to sensor measurements, where even the slightest deviations can lead to significant consequences. Renesas, a global leader in semiconductor solutions, recognizes the importance of precision in sensor applications. To address this need, they've introduced the Renesas RX23E-A MCU Evaluation Kit—a comprehensive solution designed to provide high-precision sensor measurements without the hassle of extensive hardware modifications or software development.
At the heart of this evaluation kit is the RX23E-A MCU, a member of the renowned RX MCU family. This microcontroller is a powerhouse of integrated capabilities. It boasts a high-precision Analog Front-End (AFE) that enables the measurement of sensor data with incredible accuracy—less than 0.1% error without correction. What's remarkable about the RX23E-A is that it offers a single-chip solution for achieving a maximum effective resolution of up to 23 bits in the 24-bit delta-sigma Analog-to-Digital Converter (A/D converter) without requiring any external analog components. This integration simplifies your design and offers excellent flexibility.
The RX23E-A Evaluation Kit, also known as the RSSK RX23E-A, comes with everything you need to dive into the world of high-precision sensor measurements. Here's what you'll find in the box:
Evaluation Board: The heart of the kit is the evaluation board, housing the RX23E-A microcontroller and peripheral circuits tailored for sensor measurements.
K-Type Thermocouple: Included in the kit is a K-type thermocouple, a versatile temperature sensor used in a variety of applications. It's your ideal partner for temperature measurements.
Software: The evaluation kit is bundled with user-friendly software that can be conveniently downloaded from the web. This software eliminates the need for extensive software development, allowing you to start your analog characteristic evaluation right after purchasing the kit.
GUI and Sample Programs: The kit provides a graphical user interface (GUI) that simplifies the configuration and data display processes. Sample programs are also available, making it easy to kick-start your experiments.
Emulator Compatibility: If you're into deeper software development, the kit supports direct connections with E1, E2, and E2-Lite emulators (sold separately), providing flexibility for your development needs.
Communication Features: The inclusion of RS485 and CAN driver ICs on the evaluation board opens up possibilities for communication and integration into a wide range of applications.
To truly appreciate the capabilities of the RX23E-A Evaluation Kit, let's conduct an experiment to measure temperature using the K-type thermocouple. The K-type thermocouple is commonly used in applications where high-temperature accuracy is crucial, such as in industrial and scientific settings.
1. Connect the K-type thermocouple to the evaluation board using the provided thermocouple connector.
2. Open the GUI-based PC tool program for thermocouple measurement, available for download from the web.
Temperature Accuracy: In our experiment, we were impressed by the level of precision the RX23E-A MCU and the K-type thermocouple provided. The measured temperature error remained within an impressive ±0.6°C, even when tested in a challenging temperature range spanning from -40°C to 85°C. This level of accuracy is crucial in critical temperature-sensitive applications.
Effective Resolution: The kit exhibited remarkable performance, achieving an effective resolution of 19.4 bits. This translates to a temperature deviation of a mere 0.0015°C at the root mean square (RMS) value. Such high resolution is a testament to the kit's precision capabilities.
These results highlight the evaluation board's exceptional ability to deliver highly accurate and reliable measurements using K-type thermocouples. The fact that the temperature error stayed well within the sensor's error range underscores the evaluation board's quality as a reference design. Following video shows use of GUI tool for experiments
I think for engineers using MacOS, they need to be 100% up-to-speed with VMs, because practically-speaking there's no other way to work with MacOS since so much engineering software still doesn't work natively with MacOS (part of the blame is with Apple, since developers need to purchase Apple machines to fully test, and even to sometimes to build code, whereas with Windows and Linux, VMs are possible).
The error in your screenshot indicates that 'sed' was not found. Are you using MacOS, or are you using a VM? Is it a Windows VM, or a Linux VM? If Linux, which distribution is it? Is it Ubuntu for example, or something else?
It could be a path issue (you could open up a terminal window in the VM (if you're using a Linux VM) to see if sed is recognised (type which sed to see the path that it was found at). It ought to be there by default, but if it isn't then it could point to an unusual distribution perhaps, in which case it may need to be installed. You may also be accidentally be running as root user inside the VM (some distributions will not have the default path for sed as a super-user by default).
At header you say "Analog devices has similar products which can be considered". What device did you consider?
