Which PBP Compiler are you using?

[nomada]

Hi mister_e

Today I've tried the ICd of MCSplus ... and it worked!

However initialy I found myself in troubles because I've followed the MCSplus help file schematic and it didn't worked, for some reason in their shematic they have pin9 of max232 conected trough a 100Ohm resistor...
... then I decided to implement RENTRON shematic and it worked at first attempt (they had pin9 completely free), the information provided by ICD is very complete and helps a lot to understand some tricky parts of PBP code.

The message reported by MCSplus ICD with the first schematic implemeted tells that it couldn't establish a connection.

Rentron has a very good web site!

Thank you very much for your help

The schematic shown in the MCS Plus help file uses the DB-9 pin #4 which is DTR. It may look like pin #9, but it's actually pin #4 if you look closer.

The MCS boot-loader program toggles the PC DTR output which resets the PIC via the /MCLR connection for boot-loading.

Using this particular setup with the MCS boot-loader allows "hands-free", single-click, compile & program. I.E. there's no need to press a reset switch on your development board or circuit each time you boot-load.

All the MCS ICD requires is the hardware USART interface to RX/TX. Pin #4 from DTR to /MCLR is just an auto reset circuit. Not necessary, but very handy.
