Does somebody work with ST7540 and HCPL-800J?I am doing my final project and it is almost at the end. I have probleme with data receiving on slave.My slave don't recognize any data on the line. I am sending data with 2400 bps, at 132 kHz. I think there is probleme in coupling circuit of HCPL-800J.In attachment i put a schematic of hcpl-800j.If somebody can explaine what can be wrong or give me a better solution!thanks
