a spi port without sdi would not be a spi port it would be something else
IF so what would it be called , if so more of them would be handy at times i am sure - this chip has 2 ports like this , i fear that the P!0 rgb version that uses the 3 x leds ( rgb) that is specifically used for outdoor display use of >15meters view , may need 3 streams , god hope not - ill see as i have a couple on order just to find out , when china comes back on line

i still have a way to go , with your code , i hope to get it commented well how the lib and the fonts come together with the test code for the display on the p10 so i fully understand it , which i cant say i do as yet ,

Font char sets is needed or should say font msg sets stored in external flash is need later on , so i really hope this week to get a the displays to do something meaning full

i still not seeing Oe, Lat working correctly , which is i think is bad port rewiring , but will know soon enough

the main problems with interupt routines reassign to timer2 , timer 3 used a gate pin , when was not needed , setting correctly fix it, but it effected timer 1 and as such it created other issues ,

SSP1 PPS was right , but SSP2 was not correct on the PPS originally , finally sorted that by reviewing settings, i spent a lot of time trying to make mplab -code configure to show what i wanted , which was a problem

as it turns out this chip is doing a lot of other things ,not just getting the outputs for p10 going correctly , which is so important , rf modual , terminal services , it also doing some logging of sensors ,voltage monitoring has remote config of settings, etc

timers 0-4 in use , 8 related INT services ,


Anyway see how the next days progress ill send you a commented code list of what i think is happening ,so i can follow the structure design , if you can have read see if i got wrong


Cheers
