Hi,
I'm feeling frustrated with this, but certain it's a mistake I've made but not sure how!
I'm equally certain that this isn't a labelling problem, I've not bought any blank 12F629s (08) or 12F683s (08M) and I've not had these anywhere near my PICkit (that was a 12F675 I used there) but I can't seem figure out why I can't program my 08 or 08M picaxes (had them a while and in other breadboard circuits, not programmed more than a couple of dozen times).
Vista & USB OK, when I plug into the socket on my minsumo still get a firmware check (on 18X circuits) without problem.
Breadboard now stripped to programming daughter boardboard (Manual 1, Page 7 circuit - build new early last night), the picaxe, 1A Low Drop-Out Regulator and a pack of 4 fresh AA batteries. (same battery pack as used to checked the 18X circuit and regulator type is common between circuits)
On the 08/08M I tried to read firmware version, also tried to follow thru' with connecting power after clicking the programming button to force a reset but to no avail.
This was checked on the 08 and 08M with only 4 connections on the bread board +v, 0v, Sin and Sout. The programming socket daughter board also carries the 10K and 22K resistors. I've double checked circuit and tested resistances with a meter, all appears ok.
Regulator output tested as 4.9V, testing Sin to 0V (on the chip legs) while viewing the programming editor connection test I read -0.3v and +4.6V as expected.
I trying to figure what I've missed or some other test I can do this evening. I'm thinking about connecting it to PICkit but expect to see it report protected code.... It's a while since I've used the PICkit, will the PICaxe have some other Code ID it might report?
Regards,
Colin
