#ice40 — Public Fediverse posts

The iCEBreaker FPGA dev board v1.1 is back in stock in the US store! https://1bitsquared.com/products/icebreaker #opensource #fpga #ice40 #electronics #hacking #openFPGA

​:neofox_sign_aaa:​ iceprog pushed the binary to the board. Annnd the LEDs blink now! ​:blobfoxwhoaa:​ Pretty!

mmm... FDTI driver issues it seems, but I know I installed the ftdi package? Can't find iCE FTDI USB device. Maybe permissions?

Yep! Needed to add my user to the tty group (like dialout group on ubuntu) for /dev/ttyUSB* on Void Linux.

Step 1 is Software to talk to this thing I guess. Gotta get the Yosys, NextPNR & IceStorm tools installed it seems. ✅ #FPGA #openSource #alhambraII #ice40

Determined to figure out this FPGA thingy that's been sitting in my desk drawer for almost a year now... ​:determineline:​ I have a datasheet. Let's go! #FPGA #openSource #alhambraII #ice40

Interesting SPI Routing with iCE40 FPGAs

There is now a github repository to compare the performance of FPGAs. The repository contains test cases for adders, counters and muxes. Now we know how much faster GateMate is than ICE40.

Tomorrow I try the Open source Tool chain for #FPGA first I search #Machxo3 then #ICE40. I am frustrated about the commercial license.

How and why I developed a simple Flash SPI programmer from scratch in 2025.

Say I am debugging an #ethernet project on the #ice40 #fpga of pico-ice board. I want to know the contents of some registers down in my design (which destination MAC address my #hardware tried to transmit). I don't want to use manufacturer specific ILAs and don't want to hand route a bunch of debug signals to my top level for external #debug equipment I don't have.

In PipelineC just assign to a globally visible #UART debug probe wire:

Not having #AMD #Xilinx #Vivado #Chipscope based live #hardware debug for the #picoice #Lattice #ice40 #FPGA was a little annoying

so I am hoping to revive the small pipelinec project that was sorta a build your own chipscope attempt 🤙 and demo that on the pico ice

Yay those cheap #hardware #ethernet phy #pmod -LIKE things work with the pico-ice #ice40 #FPGA . Thanks for your help with RMII interface @dutracgi ! #embedded #HDL #RTL #Verilog #VHDL #HLS https://github.com/JulianKemmerer/PipelineC/blob/master/examples/pico-ice/ice_makefile_pipelinec/ethernet_top.c

The iCEBreaker FPGA dev board V1.1 is available in the US store right now! Get them while the inventory lasts. The new version features an RGB LED, additional PSRAM chip, USB-C connector, populated “ears”, as well as length matched Pmod signal connections! https://1bitsquared.com/products/icebreaker #opensource #fpga #ice40 #electronics #hacking #openFPGA

Have been super pleased with the #ice40 #FPGA and #raspberrypi board that https://pico-ice.tinyvision.ai/ sent me to experiment with. Many thanks and I look forward to putting together a talk for intro users getting started with #PipelineC and boards like the pico-ice 🤓 #HDL #Verilog #VHDL #hardware #embedded

> Is it possible to program one MicroPython #RP2040 core from the other?

My expertise is on the #ICE40, more than the #RP2040, but reportedly the RP2040 can run two #MicroPython threads on the two cores, so. you should be able to program one from the other.

If not, you can certainly program a #pico-ice #Forth core from the first MicroPython core.

What are you trying to accomplish?

@niutech @RaspberryPi @micropython @esp32

ICE-V Dual and ICE-V Dual Fermatta

These cpus have two cores which share an ALU and control structures. On calls and jumps usually RISC-V computation pauses while the core loads the next instruction and decodes it. By alternating between the two cores, this problem is avoided. And many applications can easily be split into twoth reads sharing the same memory.
