Extending custom QEMU peripherals with properties that can be changed during runtime for interactivity and PyQt6 application for easy manipulation.

QEMU custom peripheral properties

In the QEMU TMP105 QMP interaction newsletter the interaction with an emulated QEMU component via QMP and properties was shown. Using Python and QMP it was possible to change the temperature that the TMP105 component reported by issuing commands from outside the QEMU emulation. In this post we will add similar support to the Custom I2C and Custom SPI peripherals. In the original implementation of ...

Using QEMU Machine Protocol (QMP) to interact with a running QEMU instance from outside.

Using QMP to interact with QEMU Board

QEMU Machine Protocol (QMP) QEMU is a very useful tool for learning embedded system operation since different processors, configurations and peripherals using different protocols can be emulated. For this blog I've made several custom peripherals and it is not always easy to make a demo, since some meaningful data has to be provided. For instance, in the custom peripherals examples for I2C and SPI ...
