icebreaker++-ram: icebreaker FPGA board, upgraded with ECP5 (+extra RAM)

One of the open source PCB projects designed with KiCad by Gregory Davill

Overview

Gregory Davill is a technical expert from Australia who is very famous and active in the field of open source hardware. In December 2020, he insisted on designing a circuit board every day, using KiCad to complete the circuit design and PCB layout and routing. This is the adventure-calendar-of-circuits-2020 project.

icebreaker is a very nice and handy little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
- The board design is based on the original design, simply replacing the fpga with ECP5.
- The second port of FTDI connects directly to additional I/O pins.
- Each PMOD is connected to support 4 differential pairs.
- Available in PSRAM and HyperRAM packages.

Mixed programming issues, hope everyone can give me some advice
[i=s] This post was last edited by dontium on 2015-1-23 13:36 [/i] Usually, when C calls assembly, we should be careful not to destroy the execution environment of C by embedding the assembly program.
Encoder signal input problem
Please recommend a PCI bus or USB interface orthogonal coding signal acquisition card or module. I am not very knowledgeable and don’t quite understand it!
