Serout/Serout2 and PIC18F97J60 (100 pin)

Hi gurus,
anyone knows WHY this piece of code DOES NOT WORK ???!!!???
Basically it should send serially the control byte for a MeLabs LCD display
Instead, I got just junk and instead of receiving 5 character I receice sometimes 2, some other times 3.... But anytime NOT the correct characters.
I've used all the hardware USART, so I can't use no others and I cannot even modify the board to have a different "multiplexing" solution for the hardware serial port...
I'm using a resonator at 25Mhz

Code:

DEFINE OSC 25                      'Set the Crystal Clock speed
INCLUDE "modedefs.bas"          'Inline compiler's pre-defined constants
ADCON0 = 0                          'AD converter module 0 = disabled

My settings for programming the Pic are the following:
Watchdog timer: Enabled
Stack Overflow Reset enable: Enabled
Extended Cpu Enable: Disabled

Oscillator: OSC1/OSC2 as primary, HS Osc
Fail Safe Monitor Clock Enable: Enabled
Internal External Switch Over Enable: Enabled
Watchdog Timer Postscale: 1:512
External Address Bus Shift enable: Enabled
External Memory Bus Address Mode: Microcontroller mode, External bus disabled
Data Bus Width Select: 16-bit
External Bus Wait enabled: Ignore MEMCON.WAIT, Device Will not Wait
CCP2 Mux: ECCP2 I/O MUXED with RC1
ECCP Mux: P1B/P1C On RE6/RE5, P3B/P3C On RE4/RE3
Ethernet Led Enable: LedA/LedB On RA0/RA1 with Ethernet, RA0/AN0 without

I don't know what else to thing about. Any change to have Serout (and even Serout2 and Serin at work) simply does not work.

Could be something weird with the Configuration's Bits settings?

Thank to all in advance.

Ok guys,
it definitively seems that there is something wrong in the PBP library somewhere.
The Serout (and Serout2), with PBP2.50A, and the program below, it JUST send 2 or 3 random character (yes, sometimes 2, some other times 3...)

I've putted a line in the code to flash a led to prove that the loop is going, but putting a scope on the output (on the pin PortD.7), I see only the transmission JUST after the reset and then NOTHING ELSE even if the loop is going and the led is flashing. So the instruction Serout2 bla bla bla, it is simply IGNORED! No transmissions at all, neighter the weird one. Just some character after the power-on.

The chip is again the PIC18F97J60 (100 pins version).

Any idea?

Thank you.

From one Mike to another,
I'm not sure on this, but I think that you can only use modedefs.bas and N9600 mode with the SEROUT command not with SEROUT2.

Code:

---

SEROUT2 LCD, 84, ["Hello World",13,10]

---

Thank you Skimask and Mikendee.
I've already tested the code putting 84 instead of N9600, but nothing.
Actually I modified the program in order to increase a BYTE sized variable "instead" of the 84.
So, pressig one button, I get that variable increased by 1 (and toggle a led).
Pressing another button I get that variable decreased by 1 (and toggle the same above led).

The loop is working because I see the toggling of the LED each time I press some button (debounced as well), but still nothing good...

After the first weird sending then the PortD.7 pin is just muted.
No other sending even if the loop is still going. Actually if I press one of the buttons, I see that the led is toggling.

Same result if I change on any pin on PortC.
Of course, neighter Serin/Serin2 work...

I submitted the issue to Melabs too.

Any idea in the meanwhile?

Time to break it down...
Does the old blinky LED program blink at the proper rate?

Code:

---

led var portd.7 : output led
main: led = 1 : pause 500 : led = 0 : pause 500 : goto main

---

1 second blinks?

..........never mind......................

Thank you Skimask,
is exactly what I did last night.
Conclusion:
The chip is FRIED!
There is something wrong with the PortD and PortC.
Actually a new board with another chip it work properly!

My apologises...

I've also apologized with MeLabs... even if I submitted another issue to them.
The new (old) one is related to the fact that the PIR1.5 register seems never find a character in the buffer even if I know that is sure there.
DEFINE HSER_CLROERR 1 and DEFINE HSER2_CLROERR 1 are both at the top of the program.
Things start going bad if I use some I2C command and then inquiry the PIR1.5
What I do not understand is that inquiring PIR3.5 (for the other attached device), it work regularly at any speed (between 2400 and 115200)
the only way to get data from the device attached is to use HSerin with a timeout of 10ms...
If I DON'T USE any I2C commands, both PIR1.5 and PIR3.5 reflect the correct data and behaviour...
I've already posted this strange things in a more detailed post:

Thank you all guys.
Hope in some hint...

That's weird... i'll order few sample of this chip just for fun...

Mister-e,
thank you very much for your curiosity.
Be prepared. The package IS EXTREMELY SMALL!

Let me know if you discover sothing.

Thank you again.

No problem, it's an interesting PIC anyways. I'm impressed the 40$ PICKIT 2 support it... while some much more expensive programmer i have don't :eek:
