The first two primitives from the SER/DESER family are running on the Himbaechel-#gowin architecture today! Without a video about blinking LEDs, I can only say that #TangPrimer20k and #tangnano9k blink properly :) For GW1N-9C, the LED was intentionally attached to the bottom of the chip, where IO needs to be programmed in a special way.
Since ODDR and ODDRC do not use a dedicated clock for IO, this was not very difficult. And now I will deal with very interesting primitives with IO clocks :)

The massive Himbaechel-gowin backbone is already in decent condition and works on boards from #tangnano GW1N-1 already out of stock to the last one I have #tangprimer20k😉
It remains for me to implement a large piece of IO / IOLOGIC. Unfortunately it won't be photogenic - sort of like this TBUF check on the GW1NZ-1 Himbaechel-gowin. So I won't bother with the same blinking LEDs, but know that work is in full swing🙂
#fpga #apicula #sipeed #gowin

It's very likely that #apicula will get the support of #sipeed #tangprimer20k today !

The functionality is minimal and I want to warn you not to use flash for these first versions - use SRAM to avoid getting a brick :) I warned.
