Hi Taner.
Congratulations for this job :wink:
Can you tell us what efficiency has your design ? Personally I expect more that 75%. And do you planning some kind of remote control interface ?
PIC16F877A boot loader with verifyication of programming
Please, can some one measure USB power consumption from his ICD-2 ? My unit consumption is about 100-120mA, scheme is at page 33 of this topic.
I am used PIC16F877A with zaphod42 boot loader, but some times MPLAB cannot download...
Hi, can some one tell me, what is right value for crystal oscillator of PIC18F4550, 20 or 24 MHz ? Some designs use 24MHz, other 20 MHz.
Below is a my ICD-2 clone, with USB & RS232 interface. Work well, but for me is very slowly in compare with CCS ICD-U40.
Hi, C-Man, in *.fw file is missing a bootloader. If you have original working ICD-S20 or ICD-S40 unit from CCS there is no problem, but if you make own ICD-S20 or ICD-S40 ( using old MicroChip ICD-1 or some cloning of ICD-1 ) and use firmware from *.fw file, then your ICD-Sxx is unable to update...

Hi, why not try with shift registers 4094 ? I was make a 4 digit LCD dual channel termometer and humidity meter with PIC18F252 & 4094. For LCD control are used four 4094, and 4 pins of PIC18F252. Current consumption from four 4094 is approximately 10-15 uA. Refresh rate is 64 Hz. LCD...

ccs icd clon
ICD-U use FT232BM USB <-> RS232 converter, connection is at TTL level with PIC18F252. This is an one clone of ICD-U USB interface. I'm not testing it, but thing that will be work fine. Rest of schematic is the same as ICD-S40. My Clone of ICD-SXX ( RS232 )
can be get from here...
Hi C-Man,
I have my cloning of ICD-1, modyfied to ICD-S40, but I can't upgrade firmware with icd.exe, after 18F252 has programmed with stand alone programer. I think that in extracted firmware from *.fw is missing a bootloader. Can you share your hex file for 18F252, please ?
best regards...

You can use ICD-1 to debug with CCS IDE, but firmware in ICD-1 must be CCS firmware, not an original from MicroChip. Before one year, I was cloning ICD-1 to ICD-S,ICD-S20 and ICD-S40 and I have no problem with them. I have one of my ICD-S40 cloning for sale.
Hi,
you must connect only 47k resistor from MCLR pin to VCC, then ICD-XX will work as debuger. See CCS documentation how to using
ICD, www.ccsinfo.com

I'm look for another snap.dll, becouse the original from www.hth.com have an error and don't work. Problem in snap.dll is that user data are reversed, and snap.dll can be used only if remote host use also snap.dll. For example,when I send 1,2,3,4 , snap.dll encode my data as 4,3,2,1 in SNAP...
icd-s20 hex
Can some post booload.hex files for ICD-S20, ICD-S40 and ICD-U40, becouse booload.hex file installed from icds.exe is only for ICD-S ( 3,6864 MHz crystal ) and when I'd like to upgrade CCS firmware for ICD-S20, ICD-S40 and ICD-U40 ICD unit stop to work. Thanks.
