Good question! The plan was to use it for the central alarm room in temporary hospitals where no network exists. We planned to develop a small gateway to gather all the devices alarms, linked to bed number. It was not developed, but hardwa

Yes we are :) The first days were fun. Then the french government pushed the project. Challenging, crazy, but exhausting. 25 days without coming back home! Then the lockdown did the job, and the project was not so urgent, so the ANSM (fren

Sorry for your friend. Problem with vent bag is that you cannot maintain a positive expiratory pressure (around 10mmHg of pressure during the expiration to prevent lung to collapse alveoli). For Covid-19, all the projects based on mechanize

I'll be very happy for my industrial projects if BCM2711 come with CAN or RS485 built-in, but for the moment, there is nothing planned by Raspberry... A low speed 115200 baud link does the job, with applicative CRC on both side to be s

As far as I understood doctors, in march there was no guidelines for the disease. It was considered as a respiratory disease. Later on, it was requalified as a vascular disease, scientists looked at cytokines / interleukin (I AM A ELEC

As soon as ANSM (french equivalent of US FDA) hears "linux", "wifi", "connected", they see a scary green monster... And to be honnest, I understand their point. How can you certify Linux ? So much code behind..

Short answer is no, I don't trust Rpi for vital tasks. Long answer : In this project, Raspberry is used to display curves and set some parameters. The core (ventilator algorithm) is implemented on the STM32F411, there is just a serial

If you're in the middle of a world crisis, and you need a small computer + touch screen, Rpi is THE solution. Farnell and radiospares have tons of stocks.

Qt + Warp 10... Maybe it could be possible ! But the kiss approach was great here. WarpScript includes all you need to render text, vectors, images... The limit is that I cannot use the touchscreen. Thanks for your replies everyone !

With this little SPI screen, there is no GPU behind, so no way to use DRM. If you want to run X, you also need to use framebuffer turbo driver. So everything goes through the framebuffer anyway. The fun here was to use only Warp 10 database
