Hi All!Just finshed my FSbus COM and FSkey boards!!!! Whohoo! I've been waiting all day to get to test it!Startup went ok, red diode on COM lit up, switched com and fskey into flash mode .. flash went ok, read pic also ok, CID is correct. Hexfile seems to be transferred.Measured the currents on the PIC while in flash mode, the two 5V pins ok, but the 13.5V shows 12.0V. Low ut it seems it was enough for the flash.Ok, switched it off, changed into normal mode to test the fskey funktion.Ran FSKey test, entered CID 1 as the fskey was flashed to that. Pressing the buttons connected...... Not a life sign...Tried flashing it 3 times, different CIDs, connected the buttons to different rows.... Nothing....Any hints?Olle Ramsberghttp:/ramsberg.nu

Not a life sign...Just checking: did you switch both boards to "Normal" mode?Also, check your serial cable I would think.. If it flashed OK then the ribbon cables are probably connected right.Hmm.. I wonder what else you could check..? All components (the diodes especially) are connected the right way around? These could be helpful:http://mikkila.wabbits.org/fsbus/doc/photos_e.phpI hope you find the problem!Tuomas

>Just checking: did you switch both boards to "Normal" mode?Olle: Yep, switched them to normal after flash. Both with power off and power on with a reset afterwards.>Also, check your serial cable I would think.. If it flashed OK then the ribbon cables are probably connected right.Olle: Hmm, well I can doublecheck the serial cable, but would it flash and reade the PIC if the serial cable was the problem?>Hmm.. I wonder what else you could check..? All components (the diodes especially) are connected the right way around? These could be helpful:http://mikkila.wabbits.org/fsbus/doc/photos_e.phpOlle: Nice page! What I can see, i haqve connected the diodes and the other components the right way... I will check again.Olle: I have also ony tried the fsbus2.0 beta version, so my first test this afternoon will be to test the 1.3 version and see what happens.Thanks for your help!/ Olle

Hi, i have the same problem, with low voltage in flash mode.I don't know what is going wrong. I had to increase the input voltage (just for flash mode) to ~15,5 instead of 9v and flash worked fine without errors.Eddie

Nothing....>>Any hints?Here we go.It have been little while when i last time solved problems with COM and Key boards. But.About voltages. Input voltage should be 9 volts. I use 12 volts from PC-power without any problems. You should add cooler for 7805 because it have to drop 7 volts to give 5 volt output. it will give some heat.Is you have problems getting 13.5 volts for programming mode. Problem lies somewhere near 555-timer. Check all components around 555.For programming systems uses mainly three transistors on COM board. Data reading in flash mode is done thru MAX232 chip. Same router is used when Key board sends key presses to computer.This counts out serial problems.But. What i have noticed. Some people in US have got similar problems.PIC is not using clock (4MHz oscillator) in programming mode. But it is really needed in normal operation. And in states when you say that "I wan't 33pf capacitor". What you get is actually 33nf and oscillator won't work.- Check those capacitors and solderings around that area.- Voltages. Voltages are 5v on Key board too. There is no ground difference between COM and Key board. (measured with multimeter from Key ground to Com ground should say 0v)- Try to get little higher voltages when programming.- Did you write config when programmed?- Check that 4051 chip. It is allergig to static electricity.Hmm, what else?- Jhttp://www.mikkila.org/fsbus

As JMI has suggested, check & double check the oscillator area (4Mhz) crystal & the two caps that feed it, make sure the caps are the right values & that you do not have any short or open circuits there, I built two different boards & had problems around the oscillator area, they would flash perfectly but seemed to be dead when in normal mode.For me the first board was due to incorrect cap values, the second was a hairline crack in the circuit track.The Oscillator does not seem to be used during flash only in normal operation.Good Luck Glenn.

HelloAnd I have voltage problems.I have notice the follow:If i don`t connect the fskey with the fscom and measure the pin9 and ground give 13.5 v. (the pin 9 is the output where conected directly with the pin 4 of 16f84a )But when attach the fskey in the fscom then the voltage drop in 13.1 volt.And the flashing don`t work.Also i try to increace the voltage of the fscom more than 12v but the voltage in the pin 4 of the 16f84a stay stayable to 13.1vI think something is wrong in the fskey but i don`t know where.Sorry for my bad EnglishLambisGreece

So that 13.1 volts is enough for programming. You should try to find problem somewhere else.In FSBus software there is test-program for flashing mode. Check that those signals are right. Also make those same checkings what i have told earlier. All solderings. Look for hair thin cuts, short cuts and so on.- J

Hi guys,if you don

I got it working...Answer: RTFM ;-)I had misunderstood the "write configuration". Did that after the flash... hehe...It works now, thanks for all your help! *blushing*Olleramsberg.nu
