Node Red en node-red-contrib-dmxusbpro.I

[bucovaina89]

Ik ben al een tijdje tevergeefs aan het proberen om een simpele USB convertor naar XLR(DMX512) werkend te krijgen met Node Red. Het is een convertor met een FTDI chip.

Dus ik heb node-red-contrib-dmxusbpro geinstalleerd. Ik heb wat moeten veranderen in packages.json omdat "serialport" versie 6.0.2 een dependency is. Dat heb ik veranderd naar verschillende versies van 7 t.e.m. 10. Er zijn issues in die git repo die deze techniek ook aanraden om het te laten werken. Alleen natuurlijk, hoe lang gaat dat werken .

Maar dus, ...

Nu krijg ik altijd deze error. Ik dacht dat het te maken had met wat er in de code staat voor als je van versie 9 naar 10 een upgrade doet.

code:

Ik vermoed dat de error hier ergens gaat zitten op lijn 16, maar ik ben er echt niet zeker van. Kan iemand hier misschien mee helpen?
