Multidrop bus (MDB) experience with Open AT?

Hi there,

any folk with multidrop bus (MDB) experience in Open AT?

.Thibs.

Hi Thibs,

Would this be the MDB to do with Vending Machines?

ciao, Dave

Hi Dave,

Indeed, it is for vending machines. I’ll let the customer to post here if you need more info.
Do you have some experience of it with Open AT?

.Thibs.

Hi Thibs,

I’m working with the protocol on Q2686 at the moment for one of my customers. Get your customer to PM me if the questions are sensitive and I’ll talk through what I can.

ciao, Dave

Thanks Dave! We’ll suggest him to PM you.

.Thibault.

No problems.

ciao, Dave

Coming a bit late to this, but:

MDB uses the 9-bit “multiprocessor” protocol of the 8051.

I’ve done it on 8051s:

antronics.co.uk/portfolio/viu
antronics.co.uk/portfolio/viu-4

but never on Open-AT. I guess you’d need to be using the “Open UART” stuff… :question:
