New RISC5 Spartan-7 breadboard system

Post by cfbsoftware » Sun Aug 04, 2019 1:06 am

We have now successfully ported the Astrobe Embedded Project Oberon FPGA RISC system running at 50MHz to Digilent's Cmod S7-25 board. This is a breadboard friendly 48-pin DIP form factor board built around a Xilinx Spartan-7 FPGA which can be loaded in a standard socket and used in embedded systems. This implementation includes 2 x SPI, an I2C master interface and 18 GPIO connections.

This free version of the v7.0 Astrobe system is based on the latest FPGA RISC Project Oberon sources. The board is configured for use with the Opus-Two microSD adapter card which was designed by one of our Astrobe users.
