Hi I needed a probe for metal detecting and, struggling to find anything, decided to design my own. It's just a simple colpitt's oscillator strapped to a PIC08M. As the oscillator coil comes close to metal, the frequency varies. At boot (power switch is a simple push to make button, you don't...

Hi Again :-) Having another issue, this time with HSERIN within my interrupt routine - again, stripped to the bare essentials viz ... interrupt: hserIn 0,5 gosub beep1 let flags=0 setintflags %00100000,%00100000 return First time round...

Hi All Having a bad morning here :-)) I've attached a wee bit of minimalist code to illustrate the problem. All I want it to do is on receipt of some non-synchronous serial data, fire the beeper every time that some serial data is received - I'm only sending ONE character for test purposes -...

Hi All Having some probs with tmr3setup - I'm using a 28X2 part at 8MHz in this application. The language guide says ... "The internal timer counts, when enabled, at a rate of (1/resonator speed) / 4. This means, for instance, at 8MHz the internal timer increment occurs every 0.5us. This...

As a PICaxe virgin, I thought I had nothing more to do than buy a couple of picaxe chips and lash up a cable to one of my own USB to serial adaptors and get cracking - wrong ! Fortunately, twenty-odd years of getting Macs to interface with alien worlds has stood me in good stead :-) I DID read...
