From: [email protected] [mailto:[email protected]] On Behalf Of Mitch Sent: Wednesday, March 25, 2020 4:54 AM To: neonixie-l Subject: [neonixie-l] 15 digit IV-17 VFD The vexing problem I had with this design, is that the HK16K33s I/O lines are supposed to float on initialization, to change the slave address. But the inputs to the 74HC04s are held high for the digits, and low for the segments, so the address would not change. I ended up using a separate I2C bus for the second HK, and now everything works perfectly. I just have to build a few more tube boards, and add the rest of the APA106s. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
