Guest jprobbe Posted May 15, 2003 Report Share Posted May 15, 2003 Hi there,I assembled a JDM but I get an error when I try to write to it...As indicated I check the voltage and I get a 13.3V for programming... I guess because of the two zener (5.1 + 8.2)On the JDM page it says I should get a 13.7Vdecreasing the I/O delay to 1 gives me 13.3 so ...Any idea ?Thanks Quote Link to comment Share on other sites More sharing options...

Captain_Hastings Posted May 19, 2003 Report Share Posted May 19, 2003 If yer on W2K/XP: you installed/configured the extra driver?Maybe try if it fails on another PC as well? (i had the same error with my old 300Mhz PC sometimes, but no longer on my current Athlon system...)good luck Quote Link to comment Share on other sites More sharing options...

icam Posted May 20, 2003 Report Share Posted May 20, 2003 hi jprobbe!i had the same problems/error-code by first testing my self-assembled jdm. first you should check if you assembled the jdm properly... important, if you did the same mistake than me, check the voltages for "enable clock" and "data out" like described on the jdm-page. it took me some minutes to find the error (reading pic was possible, only programming and verifying failed)... i had a short-circuit at pin 39/40 of the pic.after i removed the error and followed the instructions on the jdm-page step-by-step everything worked well.greetz,icam Quote Link to comment Share on other sites More sharing options...

TK. Posted May 24, 2003 Report Share Posted May 24, 2003 Hi,I just've got a very interesting mail from josemym@wanadoo.es - he wrote, that he was able to get the JDM running under Windows XP after he set the baudrate of the COM port to 2400 in the system setup window. Maybe this has also to be done under Win2k. Under Win ME I noticed no differenceBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...

Guest jprobbe Posted May 28, 2003 Report Share Posted May 28, 2003 Thorsten,I tried to change the baud rate of the com port but had no success.As I had doubt about the quality of my vector board prototype, I made a new JDM module on a PCB :Same result. ???Tried this morning at work on a real PC ( not a laptop like at home ) and it works great on W2K. :Ddunno if it's relying on the serial port or any Windows Service Pack. I guell I'll never now. One advise I can give is if it's not working after several tries on a comp, try another one  ;DNow I'm happy with my PIC full of bootstrap loader code.Cheers !

Mickey_Sadler Posted May 28, 2003 Report Share Posted May 28, 2003 Hi All,The RS-232 standard states that -3 volts to -25 volts is a logic 1, and +3 volts to +25 volts is a logic 0. The -3 volt to +3 volt region is a "transition region" and a logic state is not assigned. Most computers supply -12 volt and +12 volt output, but some laptops only use around 4 to 5 volts + and - and this is not enough to drive some equipment. I have seen the same problem with some modems connected to a laptop serial port. Sometimes they worked, sometimes not, and sometimes just marginal communications. That's probably why your programmer worked on the PC and not the laptop.Later,Mickey Quote Link to comment Share on other sites More sharing options...
