Note:

This tutorial only target PIC18F4550, please look for correct driver/bootloader for IC if you are not targeting PIC18F4550 as your Pinguino.

Hardware part:

• There are a lot of PIC chips supported for Pinguino. User may refer to http://wiki.pinguino.cc/index.php/Main_Page to choose other PIC chip.
• First, we choose correct bootloader for PIC18F4550.
• Bootloader is a small program that pre-program to chip so that it can help user to transfer user’s program to chip by using USB port.
• If the board was homemade, user needs to program bootloader by using PIC programmer.
• Goto https://github.com/PinguinoIDE/pinguino-bootloaders to get version 4.x bootloader. Search keyword “Bootloader_v4.14_18f4550_X20MHz“, right-click the link and select “save link as…” then save it to “C:\pinguino-11\“.
• Use PIC programmer to program bootloader into the chip.
• Now, put your chip back to board and connect to USB port of computer.
• Click reset button of the board.
• User should see this below picture once the reset button was released.

• And then it will automatically change to this a few minutes later.

• Goto device manager and look for P8 device. If user unable to see the P8 device, select “View” and click “Show hidden devices“.

• Pinguino’s IDE does not recognize P8 driver until we installed Pinguino driver.

Installation of Unsigned Driver in Win8 or Win10:

• Pinguino driver is an unsigned driver, we need to disable driver enforcement signature in order to install it. Follow this link to disable the enforcement.
• Next, go to “C:\Program Files\LibUSB-Win32\bin” and click “inf-wizard“. If user does not see this folder, please refer to here and follow the steps.
• Press again the reset button after “inf-wizard” appears and select the following item.

• There is another pop-up to ask user to save the  .inf driver file. Create a folder name “P8_driver” in “C:\pinguino-11“. Save this .inf file in that folder.

• Do not click “Install Now” after the saving, click “Done” instead.
• Goto Device manager and right click “P8“. Select “Update driver software“.
• Select “Browse my computer for driver software” and then point to the directory/folder that save .inf files just now. Click “Next“.

• If there is a warning box pop-up. Select “Install this driver software anyway“.
• User will see P8 driver in Device manager changed to known driver under “libusb-win32 device“.
