Hello ,
I apologize for my poor english langage.
I try to use a 9S08AW60 as a simple host for controlling printer. The interface is a Maxim MAX3421E Host controller. Communication is done trough SPI. Power supply is 5V for microcontroller and 3.3V for Max3421 and i've inserted an ADG3304 for voltage "transformer". I have many difficult in using SPI to send setup to the MAX3421. I can see activity on USB like busreset, SOF each ms, after i have sent order to sent it, adress change "Set Adress". Despite this i can't read anithig in return (interrupt registers, receive fifo...)
Help, i search an idea to control and fix my bugssssss.
Thank You and Best regards
Fred
