LOL re phone. I don't have a mobile
I left R8 as 510R it works better for serial data as well helping with cut off at end of serial high pulses. I'm re-doing the schematic for a V2 Master incorporating the various hacks/changes I have made.
I may well get it made up into a pcb just so I can have a nice neat one in my car!!
Vain I know.
I can't decide which new features I like best though. Some on board data storage? Wireless link to a remote display in house so you can see/hear if any issues. Data logging via wireless direct to PC and Excel spreadsheet etc. Better display with pretty graphs in car. Hmm ?
Edit
Yes Bill. Greg has summed it up nicely. I experimented with pulse and it is an option, but I went back to the more accurate serial data once I got my emi sorted.
I may use the pulse option to communicate with the slaves later when passing messages to them from the Master. At the moment the Master only sends one message ( a 10ms pulse) which means send voltage data please on Master Bus. This is passed from slave to slave.
I might expand this, and need a reliable way of the slaves receiving the message. You can't really use serial in on the Slaves 08M as they don't have the serial timeout function like the 28X1 picaxe. They could get stuck in a loop waitng for data and only a hard reset would get out of it.
But they can use Pulsin or Count so I can send LLOOOONNGGG pulses to them with different meanings.
i.e.
10ms pulse = Send Voltage Data on Master Bus
50ms pulse = Increase balancing cut in voltage by 10mv
100ms pulse = Decrease balancing cut in voltage by 10mv
150ms pulse = Adjust Voltage calculation Constant
etc etc You get the idea.
