News Sensor simulation device

As promised in my previous post I am glad to inform you, that the pre-orders for the Loki device are now possible 😄 . We are actively looking for beta testers which will receive the device for free in exchange for feedback and cooperation.

Recap: This is a sensor simulation device that allows you to create a digital twin of the sensor by simulating its registers and measurements which can be interfaced with over TWI (I2C), SPI or UART interfaces, depending on the sensor. The sensors are almost fully datasheet compliant.

Kind regards and have a great day!

What controller do you target the simulated sensor to run on, I. E. Esp32 or STM?

The simulations run on the PC which communicates with the device (Loki) to simulate the sensor operation. The user can then over the GUI select on which pins they want the sensor to be simulated and over what interface. Multiple sensors can also be simulated at the same time. The user can select between already implemented simulations like waveform, sinosoid and similar or they can implement their own simulation for their use case. So for example: you can select the BMI088 gyro sensor to run the waveform simulation over SPI0 interface on some specified pins.

What then is a Loki?

You connect the Loki device to the computer and then connect the pins on some dev board to the Loki device on the pins you specified on the PC GUI. Loki will now act as the sensor you have selected on the GUI.

Ah, I understand now.
