Hi everybody.
At the moment I’m designing a new board with the LPC2148.
I would like to connect a OLED display with 160x128 resolution, a SD-Card
and a MP3-Codec (VS1053) to the SPI bus.
According to the LPC2148 manual the SPI1 is much faster then the SPI0.
My question is how would you connect those three devices to both SPI buses?
My first suggestion is the SD-Card and the MP3-Codec to the SPI0(slow) bus
and the OLED display to the SPI1(fast) bus.
The OLED display is the one from the Univision with the size of 1.69" diagonal.
Unfortunately I can’t connect this display with the parallel interface because
I use all GPIOs for other function.
Has anyone an advice?
Thanks for the help.
Best regards
Juergen
