This page covers current downloads, upgrades and support issues relating to all of our USB PIC Programmers (Order Codes AS3128, 3149, 3150 and 3182) that run the MicroBurn (previously called MicroPro software interface.
It is ESSENTIAL that you use the MicroBurn software version detailed in the PRINTED INSTRUCTION sheet supplied with your programmer to avoid firmware mismatch problems (unless you have already upgraded the firmware of course).
If you wish to use MicroBurn 25EP and you are currently running the original version 25 (or the version 26 beta) or earlier you will need to upgrade the onboard firmware chip using the appropriate hex file contained in the MicroBurn25EP zip file. You will need a spare PIC16F628-20P or PIC16F628A-I/P chip (or programmer) to upgrade the firmware chip. Blank PIC16F628A can be purchased from our Components page (Order Code PIC16F628A).
Alternatively, you can purchase a pre-programmed firmware chip (version P018) from us from our Firmware Chips page or by calling our Sales Team on 01279 467799.
It is also important that you read the ReadMe file shown in the Notes column to avoid damaging your programmer.
|This is the latest official release of MicroPro (now called MicroBurn). See readme files in the zip download for full details.|
It must be run with firmware version P18A to operate properly.
Compatible with 9x/NT/2000/ME/XP/Vista/7.
Please see PIC Programmer forum at http://www.websitetoolbox.com/mb/diykit?forum=13943 for ALL support questions on this product.
MicroPro24 and earlier
|Sorry, version 24 and earlier are no longer available. Please upgrade to one of the later versions detailed above. Pre-programmed 16F628A firmware chips for running the latest version of MicroPro can be purchased from our from our Firmware Chips page.|
MicroChip's C compilers have a problem in that they create hex files based on 8-bit words. Never in Microchip's history have ANY of the PICs had 8-bit words. So naturally, MicroPro gets choked up on them because it never expected them to be used. This same problem afflicted several other popular programmers as well. We have written a "corrector" which changes 8-bit references to word references and allows MicroPro to accept the data. The program is included in the MicroBurn25EP download detailed above. Just run FIXHEX before trying it in MicroPro and it will fix the "problem".
You will need to download and install the FT232BM USB Virtual COM port (VCP) drivers from http://www.ftdichip.com. These drivers are being updated frequently. At this time they can be found at http://www.ftdichip.com/Drivers/VCP.htm
Select the driver file for your Windows OS version. We downloaded the Certified Version. Unzip it to a new folder in a convenient location on your hard drive or an external disk. Connect the programmer and follow the driver installation program pointing it to the new driver's folder when asked. You can download various support and help files at http://www.ftdichip.com/Support/FTDocuments.htm.
You can find the COM port number of the USB driver in the Control Panel under Ports (COM & LPT). In our system it is COM4 so when MicroPro first runs you must set the Port to 4 (under File>Port.) MicroPro will auto detect the programmer once the correct COM port is selected. NB Only COM PORT numbers 1 to 9 are supported by the programmer due to hardware limitations. If you find the driver is allocated a COM Port number higher than this you just need to plug the programmer into a different USB socket and a new number will be allocated.
You might need to make some hardware upgrades depending on the hardware version of your programmer and the MicroPro version you wish to run.
MicroPro Version 23 and above needs a 10K resistor between pins 9 and 10 of the programming socket to program 16F88 on boards 3128, 3149 (A to E) and 3150 only. The 10K resistor can stay there for other PIC programming.
This important upgrade is only required on older 3149A, 3149B and 3150v1 boards. All later revision boards do NOT need this upgrade. You simply need to add three 3K3 protection resistors to the board as described in Hardware Modification document.
Before you can use the later versions of MicroPro with 3149A you MUST change the original 4MHz crystal to a 6MHz crystal. You can order them from our Components page.
Add the protection resistors as detailed above.
A wire link must be placed on the underside of the PCB to enable the AutoProgram feature in MicroPro. See page 8 of 3149A PDF Manual (located in the MicroPro installation directory).
