I was wondering if anyone out there if could give me a hand with this.
I connected a picaxe 18m2 to a DS1307 module. Downloaded the program and ended up with nothing but 255's in all the memory locations. I read somewhere in the forum that the DS1307 might not be working, if that happens, so I checked all the wiring and it looked fine. I tried two more DS107 modules thinking that maybe the modules were defective, so I went out and bought just the DS1307 chip and wired that in, with the same results 255 in all the b memory locations. So at this point I'm
thinking it's the program, even though I've tried several versions. The 18M2 talks to an EEPROM chip fine, so it can't be the communications pins.
I've the attached the program. For some reason the forum won't allow me, to attach a JPG picture of the circuit.
