Hi Sailoog.
thank´s for your reply.
I take a look on your template until it´s ready. I hope my Python skills are sufficient ;-)
I have installed OP2 and it looks realy cool with the app character.
-MCP2515: thats cool. All works with openplotter i hope and I have nothing to do :-) .
-SC16is752: I write a script in "MCS OP App" witch writes the dtoverlay in the config.txt? Then it can handle as a normal Uart in your serial app? (It will create ttySC0-ttySC5)
-DS2482: I can load the Kernel driver for the DS2482 in "MCS App". Until its done every Sensor is reachable in:
an can call via:
I think its simular to "your" 1wire usage via GPIO4?
-MP1593: there is no problem. Until now i have not ordered the next boards. I have rerouted to pin 29 (GPIO5) O.K. for you? This pin is also not used from moitessier... Yes, script should be done to detect the power down and shutdown the system.
-MCP23017: At the Moment on my homecontrol devices I seperate the MCP´s via the adresses: HEX 20-23 is for inputs, HEX 24-27 is for outputs. I would like to do this here the same way. I only want to change the geometric design, so the Moduls can mount in the case. So its possible to put 64 inputs and 64 outputs in the case.
-MCP3424: for this I Normaly use HEX 68-6B. So you can use 16 Analog Inputs in the case. The actual boards are for 0-10V and 0-20mA. I can also design for adjustible resistance.
"- 12C modules of your other boards: This should be added to your app." => There are no further moduls. Thats all... ;-) The conector on the board is for the MCP boards. I want to place them via "Spacer" in the case. So everybody can decide for himself how much Inputs and outputs want to use....
"- What 8-28V digit. Input means?" => There are 4 Optocopler on the board wich can work with 8-28V. The optocopler is wired to the GPIO´s. So you can connect a switch or somthing simular. You can switch as example directly with the 12V on board. If the Input go´s high, the GPIO also. ;-) I have done this for fast counting. For the MCP23017 you need round about 3-5ms for reading after interrupt (I have measured that at the GeCoS : https://www.gedad.de/projekte/projekte-f%C3%BCr-privat/ ) So if you want to use it for rpm measurement the mcp is to slow and you can do this directly on the gpio....
Open-source:
I do not know "fritzing" and also not "Frankenstein-Board" ;-)
For me there are two options:
1.
I do this open-source. In principle it´s no problem for me as long as I have no high cost and only work. But then i do not sell the board. Im a buisness. If I sell parts, i must check them (surge test and so on) and do many (In germany we say) paperwork. (correct in english?) I must lable a CE on it for Europe. Means open-source yes, but then hardware only for me and all others can order directly from any supplier.
2.
I sell the board over my buisness. I think I can do this for low cost. (as i describe before round about 70€ for the board) Then I make all tests and operation manual. By the way I would write software as far as i can becouse I need this for my sailboat and I have luck on it. But the selling product is only the hardware. No software support.
Do not get me wrong: i would rather sell it without all the "additional costs". But its not easy to do this without problems later.... ;-)
