I start of using the MB library, but I have some problems... I mean the MB Comm Load work fine (no error), but when I use the MB Master, just when I raise the EN bit (without REQ, only EN) the MB Master reply me with an error 8180. I tried with different port, but without result. Someone have ideas about it? I tried to follow several guide/manuals and programs find here, but without solve my problem! Also... Just becouse someone feel interested... When I had fw 1.0.1 on CPU, had problem with MB Comm Load also (Err8180). Now with 1.0.2 the error disappere!! Tks a lot in advance!! Bye Roberto

I'm thinking the something wrong with the slave configuration, wiring or configuration... Now I'm in China and doing everythingh by teleservice, so not easy! But... The library reply me "Invalid ID port"... but if I connect the slave with wrong address or something else, should be 8186... I'm right? I'm not sure about the mean of the 8180 error expecially if I only raise the enable bit!! Anyway I will read again all the faq... hope to find the cause!! I keep the forum informed!! Tks and bye Roberto
