point, I have not even figured out how I am going to load and debug

new firmware.

2018-02-08: I received a mikroProg PIC32 debugger (Thanks go to John Legg
|
||||
of the Debug Shop!). At this point I have loaded code and can see the
|
||||
NSH prompt coming from the Flip&Click connect via an RS-232 Click board
|
||||
in mikroBUS slot A. But there is no response to serial input to the
|
||||
board. Sounds like a pin configuration issue.

||||
of the Debug Shop!).
|
||||
2018-02-09: The NSH configuration is now functional, but only with the
|
||||
RS-232 Click in mikroBUS slot B. There is, apparently, some mis-
|
||||
information about how UART4 RX is connected in mikroBUS slot A; I
|
||||
cannot receive serial there. But life is good in slot B.
|
||||
2018-02-10: Added the nxlines configuration to test the custom HiletGo
|
||||
OLED on a Click proto board. Debug output indicates that the example is
|
||||
running error free yet nothing appears on the OLED in mikroBUS slot A.
|
||||
It looks like all of the signals are present at the mikroBUS A slot and
|
||||
the proto click ohms out okay so this must be a software driver issue.
|
||||
Write only LCDs are tough to debug!

This suggests either a problem with the pin configuration or else I
