Hello, Does anyone have experience writing on a SD card in SPI mode? I succesfully managed to init and read it. Actualy, the writing procedure is working fine...
Hi there, I want to create a datalink between my pc and my pic16f628 using this diagram: http://oase.uci.kun.nl/~mientki/pic/projects/serial3.jpg But I'm...
Hi Take a look at the datalogger in: http://groups.yahoo.com/group/jallist/files/Joep%27s%20projects/ it uses an mmc card. There are some slight differences...
hi Diederick, ... Yes ... No, hardware R232 requires inverted signals, this circuit doesn't invert :-( ... Remember, voltages are always relative. Because the...
On Thu, 02 Feb 2006 17:23:29 -0000 ... Thank you, but menatime I found that my SD card does not allow writting on the first 32Kb of data. Starting to write...
Hi Stef, Thanx for your reply! But I'm wondering does this circuit works as well as the with the max232 ? (qua data corruption/ transmission speed) Thanks, ...
... enough ... be carefull to avoid earth connection of GND in your application (PC gnd is earth connected via supply and mains socket) cheers. Vasile...
How about it hardware guys, any problems with allowing I2C and SPI chips to share the same bus? Only problem I forsee is with the added capacitiance for the...
... always a nice idea to think about, I guess you're talking about just one I2C master, being the PIC itself ? In those cases were I needed both, I went for...
Hi, I'm using ic2 Master code writen by Javier MartÃnez for bigtcp where I can comunicate with external eeprom. I'm wondering is there ready to use code for...
hello sir, I have installed JAL on windows 98 but im unable to compile it. what is the "source code" you are talking about? me being a beginner,would like to...
... itself ? Yeah, all I need the I2C for is accessing some EEPROM's. ... command ? I think I have a soln. figured out to keep that from happening. After...
hi Shawn, ... looks like a very clever solution, my compliments ! I suppose R1 and R2 are small (less than 1 k) Why use C1 and C2, they slow down the max...
Hello, I'm just investigating the JDM schematic at: http://www.jdm.homepage.dk/newpics.htm From what i read in some web pages, it looks like Q1 from schematic...
I think that Q1 is actually being used more for a switch than anything. Due to the required power-up sequence to place a chip into programming mode, it is ...
Here is all i found about explanation for this JDM thing: http://www.talkingelectronics.com/FreeProjects/MultiChipPgmr/MultiChip Pgmr-P1.html Sorry if it too...
... is ... To understand JDM philosophy, you need to see the reference of the voltage which is GND for the RS232 and, in the same time VCC for the PIC(GND of...
Well, i posted in a reply on my first message a link where i found some explanations. Maybe the JDM designer is good with electronics, but his english is...
... His language leack is compensated by a good schematic. Language is not everything as long I understand your problems and you understood my opinion. ... how...
hello, i wanted to know what is a bootloader and do we need it when working with with a wisp628? in case we need it how do we design it?i am using pic 16f84a...

Tried to use a USB (CDC demo) adapter with a WISP628 Xwisp2w reports: xwisp2 version 1.8.01 for Windows (Oct 24 2005, Open Watcom C 1.30) Using serial port...
Hi Dave, ... I have never tested Xwisp2[w] with a USB-serial adapter (I have none). So I'm guessing: the driver software doesn't support the (Windows) ...
Hi, Can someone please help me. I'm trying for the first time, to program a PIC 16F628with the wisp 628 programmer. I can comunicate with the programmer (it is...
