Hi All
I am building a "Gym Bean" (my name) for my business consultant and as part of a possible run of "Gym Beans" as kits for interested parties!
I have soldered together a prototype as carefully as my hands and eyes will allow but I can't seem to download a program to it?
When I try and download a program I get the generic respose of "hardware not found on COM3"!
This all reminds me of my first steps in picaxe a fair few years ago!
my PCB design is a little unusual for one with a reasonable experience of this forum but hey to make an omlette you have to break an egg or so?
so putting my first foot (in it) first... It doesn't have a conventional CON039 download socket!
(I can hear you tutting before I even finish my discription!)
But because it is not designed to be reprogrammed it has a simplified 3-pin female pin header.
I can use this interface to programm the SMD PICAXE in dire need or in the case of the prototype, repeatedly.
I am aware that this breaks a golden rule but I've broken another...
I've run tracks between the pads of 1206, SMD, resistors and capacitors; two in places!
I am after some insights concerning fault finding of SMD designs from those that are in the know
Kind Regards
Rickz
Here are my PCB design and the cct dias I'm working from.
