Pi Brigde Connect: attaching own hardware
Posted: 11 Jul 2019, 13:31
Hi,
as far as I understood there is no plans for a "maker kit" for the "Pi Connect" side of the Pi Connect+. I would need to design a custom module that stays in house and is not sold to any endcustomer containing an FPGA . We are a research institute(non-commercial/non-profit) building our own instruments for atmospheric measurements I like the whole eco system as it is ideal for our everyday business (Analog Sensors, Valve Control etc) except for a few special functions we would need.
As far as I understood it the connector in the Pi Connect has a UART, SPI and a INT pin as shown in the schematic
Are these pins accessible from userspace e.g. exposed as /dev/spiXYZ and /dev/ttyXYZ or is the pibridge kernel modul having it's thumbs on top of those?
If it is user space accessible, can I buy a small quantity of the connectors and bridge plugs that are used e.g. in the M-Bus module (the whole housing of the module would be even cooler because i need some sort of coax connector for my application (fast Counter/Pulse Generator).
If I need to sign an NDA this would be possible.
I still think you should heavily consider offering a maker kit for the connect+ in case my assumptions with the user space access is true because this will be way less complex to implement then the other system with the STM32 and the whole piconnect stack on top.
