Triple PWM Testboard

PIC18F1330 and high power PWM

 

Just for fun I developed this neat, little PWM evaluation board. Containing a USB interface, a rotary encoder and three half bridges capable of providing 8A at 100V max, this board provides a very versatile small, yet powefull development platform.

ICD2 vs. ICD3

Debugger battle

 

A few months ago, Microchip announced the new ICD3 In Circuit Debugger. There is only very limited information available on the advantages of the ICD3. So I decided to buy one, test it and compare the new unit with my 3 years old (still working) ICD2.

IC decapsulation

Wie bekomme ich einen Chip auf?

 

Jeder kennt sie, die kleinen schwarzen Käfer, die scheinbar nur aus Plastik und Beinen bestehen. Möchte man wissen, was sie machen, notiert man sich die Typennummer, und schaut in das Datenblatt des Herstellers. Wie aber nun der eigentliche Siliziumchip aussieht, auf dem die ganze Magie passiert, bekommt man nicht raus. Nur ganz selten sind in Datenblättern Bilder vom Layout des Chips zu finden, gelegentlich geistern ein paar Bilder im Netz rum.
