Um die Verwendung von ISP auf der Platine zun ermöglichen dürfen ISP-Pins des ATMega328 nicht belegt werden. Dies hat zur Folge, dass nicht alle wichtigen Funktionen der Maschine auf einer zusätzlichen Box belegt werden können. Abhilfe wird mit Jumpern geschaffen. Von zwei ATMega328 Ausgangspins (PD1 und PD2) kann ausgewählt werden, ob das Signal den Bunker oder die Dammaufnahme ansteuern soll. Andere Belegungsänderungen sind während Laufzeit nicht möglich und müssen durch ändern des Quellcodes und Neukompilierung gemacht werden.

Samro Bedienbox: common questions
What microcontroller does the Samro Bedienbox use?
The Samro Bedienbox is built around the ATMEGA328P-P, from the AVR/Arduino family.
How big is the Samro Bedienbox PCB?
The Samro Bedienbox measures 124 × 47 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Samro Bedienbox?
92 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Samro Bedienbox design files?
From the al3c00/Samro_Bedienbox repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Samro Bedienbox design in my own project?
The repository has no license, so all rights stay with al3c00. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Samro Bedienbox without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
