Ahah !
finally got time to suss out the zmax/ECD issue..
my capacitor is not big enough for the low frequency, short duty stuff.
I could tack a capacitor on the meters and it would work .. but its messy .. instead, I am going to order some bigger caps and get them here ASAP and do it properly.
Is that ok with you guys or would you rather have a non zmax approved meter faster ?
I have the rest of the parts and have 32 meters half assembled, just missing displays and connectors. While waiting for caps I will do kore work on the code anyway, zi have found a bug where a mod changes from pwm to linear mode makes it impossible to change modes, I might change the mode switch timing a bit too.
Any suggestions from you guys ? you seem pretty switched on.
There is no way to just do it in code, the micro does not even get to boot up as is.
In short .. if your meter works with a vmax, then its had the input cap removed, clock frequency increased .. to make it work with a zmax .. need to add 33uF or more to the 3.3v rail. I just did a bunch of zmax tests with a capacitor added on the header pins.
