Pic18f2550 Usb Driver For Mac
This is here only so search engines can find it and other people can avoid this mistake. I bought a from, intending to program it from my. Long story short, there appears to be no Mac OS drivers for the USB chip. I can find lots of advice online that tells me about PC drivers, but I have a Mac, so that is not useful.
Seemed to be making a stab at it (in particular, his vendor ID matches), but his page is two years stale., but those seem slightly non-serial (IP?). Allegedly a serial driver, for a variety of devices. Perhaps it will suffice to edit the kext properties. I’ll update this if I succeed.
If YOU succeed (with a Mac, not a PC), please let me know in the comments. Otherwise, this is a dead end. This also suggests that communication with between the USB on a PIC18F2550/4550 will not work so well.
That seems implausible, but lack of a driver, is lack of a driver. Update: libusb (from MacPorts, for example) can see devices without kext drivers. I bought a Pickit2; that seems to be the better choice, and both Pk2cmd and piklab can see it (note that piklab from MacPorts does not build out of the box because it depends on arts, which is broken). I have not yet successfully programmed the PIC, but I have not yet given it a serious try with the new programmer. Update 2: The new version of Piklab at MacPorts recognizes the Pickit, but is surprised by the firmware version. Pk2cmd seems to work, once the firmware upgrade is applied to the Pickit.
To do that, you must install pk2cmd, and then type “pk2cmd -DPK2V023200.hex” to download the new firmware. MacPorts has support for sdcc — no, not really, things fail later. Better to follow, which first require installation of. Gputils you can download from sourceforge. Be sure to choose a directory that has no spaces in its path name. Then configure: “./configure –prefix=/opt/local”, and “make”, and “make install”. This installs it into the MacPorts /opt/local area, which might be a mistake, but that’s a problem for another day.
It seems to build and install ok. Using the instructions above (which seem a little dated, I sent email to the author, but no reply yet) I got a good deal further and installed sdcc, but assembly of part of the test program failed.

It could be for some stupid reason, but I ran out of steam. Mail to author: Your instructions are more helpful than anything else I have come across, but they seem to be getting maybe a little dated, and there's at least one step missing. Compiling/Installing the Remaining Device-specific PIC Libraries this part doesn't match what is there any more; perhaps it is not necessary, I cannot tell for sure.

I am working on PIC18f controllers with USB peripherals and i would like to take advice from those who have worked in similar field. How do you deal with things like: 1.Some times My pic enumerates well showing Device Recognized and some times it pops up like Unknown device. What should be the real cause and how can i fix it?

Im confused about where to look for leaks in this problem. The firmware for the USB communication is taken from this: I suspect this is not a h/w problem as i'm using a crystal oscillator of 16mhz. I would like to have your insights to debug this project. Yours faithfully Arookie. I had the same issue. The cause was the tolerance and stability of the chosen oscillator. I had chosen a ceramic resonator and this was not stable enough for operating the USB.

Sometimes I got Unknown device. I replaced my clock source by a crystal with the right stability and tolerance and everything worked perfectly. What kind of clock source do you use? What is its tolerance? Do you have any mean of measuring the clock of your system?(without probing the source directly, which could change its frequency).
