I am now building up this version. Looks good so far. I'll post the results when it is finally put together.

> Still without USB interface .... :-(( Why USB interface ??? Microchip USB implementation is slowly comparison to USB/COM interface with FT232B I'm tested ICD2 clone with FTDI chips and all is OK :-) Is easy modify USBCOM converter and ICD2clone to power from USB But USB power is limited to 500mA :-( regards Kosta -- http://www.piclist.com#nomail Going offline?

Joan, its cheaper here in Tucson, AZ to buy the USB to Serial cable-type adaptors. I paid $19.00 USD for mine. Works on everything I've tried, and probably works on this just as well... --Bob Joan Ilari wrote: > Still without USB interface .... :-(( > > Joan Ilari -- Replier: Most attachments rejected -------------- Bob Axtell PIC Hardware & Firmware Dev http://beam.to/baxtell 1-520-219-2363 -- http://www.piclist.com#nomail Going offline?

hi kosta what's the improvement of the new icd2 clone over the old one? tino ************************************************************************ ****************************** >{Original Message removed}

> hi kosta > what's the improvement of the new icd2 clone over the old one? - switching PSU for VPP - cheap PMOSFET switch - new design PCB - correct few small mistakes regards kosta -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Hi All, I've been trying to get a PIC talking to a Trimble Lassen SQ GPS module (3.3v) with no success so far. Without flaming me for being an idiot <g>, can anyone tell me by reading the below excerpt from the Lassen manual whether or not I need to do anything to the signal before feeding into my PIC? Note again that the Lassen is a 3.3v device. The manual says re the serial interface: As an embedded design, the Lassen SQ GPS provides direct CMOS compatible TTL level serial I/O. The RX and TX signals on the J2 I/O connector are driven directly by the UART on the Lassen SQ GPS. Interfacing these signals directly to a UART in your application circuitry provides direct serial communication without the complication of RS-232 or RS-422 line drivers. Note - The serial I/O signals on J2 are TTL level. They are not inverted or driven to RS-232 levels. Thanks! -- http://www.piclist.com hint: The PICList is archived three different ways.

The PIC's UART input uses a Schmitt trigger and the minimum input high threshold is 0.8Vdd, or 4volts for a 5v Vdd. Clearly the PIC would never see the 3.3 volt output from the GPS. You certainly need something in the other direction as well (if you are transmitting data to the GPS). Injecting a 5volt signal into a 3.3volt part will cause any input protection diodes to conduct, potentially causing unexpected operation or possibly even damage. A simple current limiting resistor and a schotky diode to clamp the level to the 3.3volt supply would probably suffice.

is there a requirement to do some modifications to the former icd2 clone, to correct the 'few small mistakes', or what will my problems be, when i've already bought the old version of your icd2 clone? tino ************************************************************************ ****************************** >{Original Message removed}

does this mean that i will run into troubles, when using the old icd2 clone? how do I have to modify it to avoid troubles? (I've just got your icd2 kit recently, but have not yet soldered it together) thanx! tino ************************************************************************ ****************************** >{Original Message removed}
