First of all, please excuse me for my english, this is not my mother tongue...
I have a problem with SPI on MC9S08DZ128. I would like to make it communicating with an iLCD. Here are its datasheets :
I am able to write to the iLCD and use the commands I want. But I can't read from the iLCD. For example, it should send 0x06 as an ACK for each command....
I have noticed that on the appnote, the MOSI is at low level in idle state, but in my case it is high in idle state... what could be the reason ?
I have tried to send a "get data size to read command" but when there should be something on MISO, there isn't anything. The only answer I get is a byte that seems to be 0x01 every time I send 0xAA (this is the start of each command) but the MCU isn't able to read it.
What should I do please ??
Thank you in advance for your help.
