Multi Gauge Controller MG15

Prevac · 2016 - 2017 · team project

A vacuum controller measuring from atmosphere down to UHV: four active and up to three passive gauges, at home in any bakeable or non-bakeable HV/UHV system.

My scope

Mainboard (PCB) on STM32F4 and its firmware - multichannel DMA, QSPI, ADC multisampling (C)
24-bit ADC board resolving single microvolts (PCB, analog + digital)
Passive-gauge power supply built on a resonant converter (PCB, analog + digital)
The embedded Linux system the device runs on - build and configuration
GUI layer in Qt/QML and the C++ control software on AM3358 ARM Cortex-A8

Zephyr RTOS - upstream

Collaborator status: low-level drivers, nrfx integration with the Zephyr shim, device tree and subsystems. The five pull requests on the Nordic & Zephyr page are the short version.

Off duty - bikepacking

I run a travel channel on YouTube and Instagram: bikes in Peru, Iceland, Málaga in winter. Long descents teach patience with a debugger.

Frequently asked questions

What is the Multi Gauge Controller MG15?
A vacuum controller by Prevac measuring pressure from atmosphere down to UHV. It handles four active and up to three passive gauges and works in any bakeable or non-bakeable HV/UHV system. A team project from 2016-2017.
What was his scope on MG15?
The STM32F4 mainboard and its firmware (multichannel DMA, QSPI, ADC multisampling in C), a 24-bit ADC board resolving single microvolts, a passive-gauge power supply on a resonant converter, the device's embedded Linux system, and the Qt/QML GUI layer plus C++ control software on an AM3358 ARM Cortex-A8.
What are his Zephyr RTOS contributions?
Low-level drivers, nrfx integration with the Zephyr shim layer, device tree and subsystems - under Collaborator status. Five selected pull requests in zephyrproject-rtos/zephyr and nrfconnect/sdk-nrf are linked on the Nordic & Zephyr page.
What about outside work?
A travel channel on YouTube and Instagram - bikepacking trips through Peru, Iceland and Málaga, among others.
