* The [[:boards:sbc:yaz180|YAZ180]] was my hardware build through 2017 and 2018. It is now pretty much finished on PCB version 2.4 and is in daily use. | * The [[:boards:sbc:yaz180|YAZ180]] was my hardware build through 2017 and 2018.

* I've recently built a IEEE-754 compliant 32-bit floating point library //[[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/math/float/math32|math32]] //for z88dk, which can be used with both sdcc and sccz80. It is the only (to my knowledge) floating point library which supports both the z180 **//mlt nn//** , and the ZX Spectrum Next **//mul de//** instructions, which are used to deliver a substantial performance improvement over "soft float" libraries. The z80 version of the //math3////2// [[https://github.com/z88dk/z88dk/wiki/Classic--Maths-Libraries#benchmarks|library benchmarks]] pretty well too. | * I've recently built a IEEE-754 compliant 32-bit floating point library //[[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/math/float/math32|math32]] //for z88dk, which can be used with both sdcc and sccz80.

Unrelated to retrobrew, the things I'm known for (measured in internet hits) are throwing a freeRTOS version for Arduino into a library called unimaginatively, [[https://github.com/feilipu/Arduino_FreeRTOS_Library|Arduino_FreeRTOS_Library]], and for [[https://feilipu.me/2013/07/16/paywave-paypass-deletion-via-rfid-antenna-kill/|punching holes in my credit cards]]. | Unrelated to retrobrew, the things I'm known for (measured in internet hits) are throwing a freeRTOS version for Arduino into a library called unimaginatively, [[https://github.com/feilipu/Arduino_FreeRTOS_Library|Arduino_FreeRTOS_Library]], and for [[https://feilipu.me/2013/07/16/paywave-paypass-deletion-via-rfid-antenna-kill/|punching holes in my credit cards]]. |
