RIP.

this is what a lightning strike fried last night at 23h37.

I am close to crying and am now accepting HW donations.

but I am still proud not to be that German that I have an insurance for this.

the successful anglerfish goes into revision two with the tiniest changes.

#anglerfish #anglerfisch

definitely it's alive.

#FPGA #rainbow #bare_metal #ice40 #up5k #verilog #vhdl #amaranth #yosys #nextpnr #clarie

my upcoming FPGA dev board "#bare_metal".

most tests are done, most changes and bugfixes are in this V2. not sure when I got time for a "tapeout" ;)

- 16x8 SPI based RGB LED display
- single PMOD interface
- OK button and D-pad
- USB bootloader
- 3 user bitstreams by default, extendable to dozens
- LiPo battery with protection and management
- comes with a PCB stand
- PCB stand comes with pinout tables

not so far off...

das ist heute. und das ist das beste Kit. ever.

looking for (more!) tweezers for my workshop at 16h45 at GPN

my VGA PMOD adapter overtook my "bare metal" FPGA dev board =)

grab it while it's still warm, or wait for the full story!

the anglerfish, now in my shop at lectronz:

have your kids read under the blanket.

and learn to solder.

time will tell...

any SPI flash experts?

either winbond smokes bad stuff, or I accidentally broke their security or JLC mounts counterfeit parts.

this is a 16MB flash, specifically a winbond W25Q128JVSIQ.

usually you R and W the 16MB and that's it.

but the device has also "security registers" 1-3
in each of the three "regs" you can write 256 bytes, and optionally lock them.

I used this feature, in SR1 I place a URL, and a serial number and a UUID, etc.I didn't touch SR2 and 3.

now three is a odd number

it's ALIVE!

blinks a first hello world, and that "/CDONE" LED is finally off

#fpga #bare_metal

working in a moshpit now.

delicate SMD bodges work out great.

@tanavit@toot.aquilenet.fr melting rock to glass was done near La Rochelle.

@tanavit@toot.aquilenet.fr at around 49° north (baviere).

oh, and it was no experiment, it's series (serious?) production!

;)
