README
GrasPiB_AR488_Adapter/README.mdGrasPiB Arduino Micro adapter
A simple adapter board for connecting the GrasPiB Raspberry Pi hat to an Arduino Micro running the AR488 firmware.
AR488 configuration
Pin assignment is compatible with the default AR488, except for the TE and DC control signals for the SN7516x bus drivers, which need to be enabled in the AR488_Config.h file.
In the AR488_Config.h config file, search for the Enable SN7516x chips section and modify it as follows:
/***** Enable SN7516x chips *****/
/*
* Uncomment to enable the use of SN7516x GPIB tranceiver ICs.
* This will require the use of an additional GPIO pin to control
* the read and write modes of the ICs.
*/
#define SN7516X
#ifdef SN7516X
#define SN7516X_TE 12
#define SN7516X_DC 11
//#define SN7516X_SC 12
#endifNo other modifications should be needed to use GrasPiB with an Arduino and AR488 software.

Questions
How big is the GrasPiB v1 PCB?
It measures 85 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GrasPiB v1 use?
45 parts, built around the MAX3232ID, SN75160BDW, SN75161BDW and LM2576S-5.0. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the GrasPiB v1 KiCad files?
From the an-ven/graspib repository on GitHub, at the commit this page was made from: the board is GrasPiB_v1.kicad_pcb and its schematic GrasPiB_AR488_Adapter/GrasPiB_AR488_Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GrasPiB v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask an-ven before reusing the design.
