neue Version: MCU Benchmark Test HaWe Brickbench 2.2
es werden jetzt immer sowohl fp-32bit (float) als auch fp-64bit (double) getrennt getestet, soweit verfügbar (betr. vorw. ARM und ESP MCUs und Raspi);
für AVRs wird der 32bit-fp einfach wiederholt, soweit ja kein double zur Verfügung steht (ohne "Strafpunkte", ist daher zugegebenermaßen nicht ganz "gerecht"):

Man kann die Brickbench-Tests durchführen, auch wenn kein Display angeschlossen ist - das ergibt dann ntl. keine verwertbaren Ergebnisse für den Grafik-Benchmark, denn er wird dann nur "virtuell" durchgeführt; der Rest an Tests funktiniert aber dennoch korrekt.
Andere Grafik-Libs können aber selbstverständlich alternativ eingebunden werden.
es werden jetzt immer sowohl fp-32bit (float) als auch fp-64bit (double) getrennt getestet, soweit verfügbar (betr. vorw. ARM und ESP MCUs und Raspi);
für AVRs wird der 32bit-fp einfach wiederholt, soweit ja kein double zur Verfügung steht (ohne "Strafpunkte", ist daher zugegebenermaßen nicht ganz "gerecht"):

Man kann die Brickbench-Tests durchführen, auch wenn kein Display angeschlossen ist - das ergibt dann ntl. keine verwertbaren Ergebnisse für den Grafik-Benchmark, denn er wird dann nur "virtuell" durchgeführt; der Rest an Tests funktiniert aber dennoch korrekt.
Andere Grafik-Libs können aber selbstverständlich alternativ eingebunden werden.
