Server Hardware for openplotter?

[Sailoog]

Hi Sailoog,
thanks for your reply.
See in red:

Hi, I have just find out this thread. That sounds promising. I have not read all posts, I need some free time but here are my first thoughts.

- It would be perfect that you could use the current software features of Openplotter so you do not need to program anything. The Pi supports the SC16is752 directly by dtoverlay. For the MCP2515 there is a part of software avalible. Is there a better possibility to intigrate this in openplotter? Can I integrate the MCP23017 and MCP3424 directly?
- Please make this compatible with moitessier hat and pypilot!! It´s conform with moitessier. I dont´t know the pypilot hat?
- I think RPi can not manage multiple EEPROMs and moitessier hat has already one. I don´t need a eeprom?
- We do not need RTC. I have write it before. I use the pi for different thinks and my GPS is not active all the time. But if nobody use this i delet it...
- N2K is ok but instead of NMEA 0183 in/out I prefer to have digital and analog sensors. NMEA 0183 could be connected by USB with cheap converters. I use at the moment a Logilink AU0033. I have always problems with this.... I don´t want to do this through usb....   Becouse of that I wnat to use the SC16is52. But later I can make different versions without NMEA0183... That´s why I made the board...
What you mean with sensors? Analog and digital I/O´s?

Moitessier hat uses SPI (CS0) and I2C. Pypilot uses UART and makes an intensive use of I2C (IMU). I think you have many I2C devices and this could be too much for the poor raspberry I2C interface.
For the MCP2515 I use SPI on CS1. I don´t need uart. But all other devices runs over I2C. My digital I/O uses an MCP23017 and the Analog uses MCP3424. (Design on PCB for 0-10V and 0-20mA) usualy a requeust (read/write) needs ~2ms. Because of this I want to put also I/O´s directly on the board for rpm and other highspeed applications.
Can you give me more Informations from pypilot hat?

OpenPlotter is already ready for MCP2515. MCP23017 and MCP3424 will need some python scripting and OP integration as tools.

Pypilot is not a HAT, it needs an IMU connected by I2C and a motor controller board connected by UART. It also needs NMRA 0183 devices connected to any serial port. It needs an intensive use of the IMU data and you have many I2C devices...

You need an eeprom only if you have to load a device tree for your HAT.

RTC optional is good for me.

Yes, analog and digital I/O. We do not have many free GPIO to connect sensors like motion detectors, switches, float switches, door switches... and we need A/D conversion. Now we use MCP3008 by SPI1

Have you considered to add an small battery to work as UPS.
