Explorer 16/32 Schematic pin layout mismatch?
I have an explorer 16/32 board and a PICMZ322048EFH100
I was trying to use one of the on board switches for a simple change notice notification test and couldnt get it working. Which lead to various investigations.
I ended up setting all the Ports as Digital inputs with pull up, and monitoring Ports A-G, pressing one switch at a time to see which Port registered the change.
My results were:
//sw3 - nothing changes
//sw6 - rd13 changes = Pin 80 EBID13/ETXD3/PMD13/RD13
//sw5 - ra7 changes = Pin 90 TRD3/SQID3/RA7
//sw4 - rf8 changes = Pin 58 EBIRDY2/RPF8/SCL3/RF8
The explorer board schematic shows:
sw3 should be Pin 83
sw6 should be Pin 84
sw5 should be Pin 92
sw4 should be Pin 80
But when those pins are looked up in the PICMZ322048EFH100 reference doc:
Pin 83 = VDD
Pin 84 = VSS
Pin 92 = VSS
Pin 80 EBID13/ETXD3/PMD13/RD13
Im not sure if im missing something or the board schematic is wrong, if anyone knows and could clear this up id appreciate it.
