spi voltage
Hi,
Anyone have the reference design/recommendations for an interface circuit between the PC parallel port and a device using SPI protocol? The main purpose of the interface circuit is to convert +5V output of PC parallel port to +3.3V which is going to be used by SPI protocol.
Thanks in advance.
