When I was designing my clock I decided to run the uC at 3.3V since the gps and rf modules I wanted to use run at this voltage.
In order to communicate with the HV5522 I used a very simple bi-directional mosfet level shifter. I read about it on a app note and I use it since then. Although with the 5522 the link doesn't need to be bi-directional I just went with whatever I knew. http://www.nxp.com/documents/application_note/AN10441.pdf Best Tobias -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
