Thank you very very much, now I will use it to Arduino Nano and Mega. Il will be able to cascade multiple 8255 with cascades TTL 74138 for the Chip Select (CS '). This will be a good practice, now Because of you and your well explained and professional teaching I can go on with my project. So many thanks ! - Jean, Canada
