Interrupt on startup
I have written a flowcode program in Flowcode for an 18F72 PIC. I am testing it using the eBlocks system - so I assume all pins are terminated correctly and not floating. Port A is not used, Port B is inputs, Port C is outputs. It works a treat in simulation, with the RBchange interrupt working perf...

Re: pic 16F88 I/O port issue, any suggestions?
I must agree with the concern of other contributors. I was sold this as a teaching aid, and for a simple intro to programming I need my students to turn on some lights, respond to some switches and understand interrupts. The use of interrupts fixes Port B as interrrupts ( as with the eBlock input bo...

Re: 16F84 Port A
I am a little uncomfortable making solder connections onto the multiprogrammer board.
Is there a good location to do this on the board which would be easiest.
Also, would it invalidate the warranty?
Cheers

16F84 Port A
Hi Can I just ask you to clear something up ... I am teaching PIc programming for the 16F84 using your E-blocks mutliprogrammer development board, and associated e-block led and switch modules. I realise that PortA RA4 on the 16F84 is dual purpose and can be used as an output of used with an externa...

Re: Changing Target
Also another problem just found .... When I look in the 'Configure' screen for the target, I am happy that the Watchdog timer is off. See attached WatchdogError1.jpg. When I look in the 'Expert Config Screen' I see that it says the Watchdog Timer is ON. See attached WatchdogError1.jpg. Which is corr...

Changing Target
I have a flowcode program debugged and working in the 16F84. I now wish to load it into a 16F88. To do this I select the 16F88 in the Chip - Target menu of flowcode. It compiles and saves fine. The target select screen dump is attached.(ChipError#1.jpg) When I compile to chip, I get an error saying ...

Re: Cannot get going at all
A new board works with the new power connections- although the original one now won't program. I assume something has failed due to the incorrect power connection. I have a supplementary question now I am going ... I have written a simple nested loop to count down from 65535 to zero using two variab...

Re: Cannot get going at all
Aha, I had the power going into the V+ screw terminal - I assumed the +14V terminal was an auxiliary output. I will test the new setup later - is putting 13.5V into the V+ terminal likely to have damaged the board? Unfortunately, nowhere in the documentation can I see the fact that the power has to ...

Re: Cannot get going at all
Thanks for the replies. I will check on Monday - however the multiprogrammer is exactly as sent - I simply removed it from the box, checked the jumper settings and plugged it into a power supply. I doubt if there is more than one chip on there, as they would have been put there by yourselves. Can yo...

Cannot get going at all
I have a new Multiprogrammer, LED board and flowcode. I have installed all the software as recommended and have successfully written a simple flowcode program, which runs fine in simulation. I have connected the multiprogrammer - complete with 16F88 as delivered - to a 13.5V DC supply, have set the ...
