keil arm tutorial
I am in a similar situation, and have been looking into same issues.
I decided to go with the Philips LPC 21XX series. They are cheap and there is a community of developers sharing experiences.
LPC 21XX chips have built-in bootloaders and software can be loaded from the...
Re: Programmer
Search this forum for EPIC programmer. It works flawlessly.
JDM works too, but it gets power from the serial port and not all serial ports may supply enough volatge and it can be tricky to get it to work.
Re: Linux and Windows XP
You can restore your boot menu by booting your first install CD and opening a terminal and using the chroot command. You can also use Knoppix or any other bootable Linux CD. Using the chroot command you can give any command as if you are giving it from a terminal on...
Re: 8051 lock breacking
It depends on how bad the attacker wants to read the chip. I have seen some research slides whrere the attecker dissoslves the plastic chip package with an acid that dissolves the package but does no harm to the silicone chip. Then the chips memory is covered with UV...

jdm programmer 18f4620
I managed to get EPIC to program the 18F4620. Soldering a 100nf cap between the VSS and VDD lines of the ZIF socket did the trick.
18f542
Hi,
I built the EPIC programmer. It programs my 18F542 chips, but when it comes to the 18F4620 it fails.
It cannot even erase the chip. Rads 0000 all the time.
Any pionters ?
If they are open source tools, you can compile them yourself. If comercial, it depends on the vendor, and I do not think a vendor would go a "Redhat only" way.
IMHO Mandrake is better. Why ? You may ask.
-- Great package manager
-- Nice selection of software
-- Good hardware detection, and easy to use configuration tools

Hi,
**broken link removed** has some AVR GCC code for graphic LCDs based on HD61202 or KS0108. You can usa that as the base of your project.
As for what do do with the header you get.
