I am developing an application that I would like to be able to save some simple details, potentially some usernames / passwords that would be stored and used to verify logins when someone tries to access the device using a serial connection from a WPF desktop application I also am developing.
I would prefer to not use a SD card module if at all possible, because I am talking about pretty small amounts of data - I do not need to continually store results or anything, only add new user information periodically.
I don’t know if this is even possible, but was just curious if there was some way of doing this.
That is exactly what I am looking for! It’s a shame it is discontinued though… I was not able to find it posted for sale anywhere. Are there any possible alternatives or am I going to have to consider using an SD card (which would be overkill)?
FEZ Spider, and yeah I just opened a few things in regard to this and saw someone mention the possibility of EWR. It is a bit confusing to me though - is the data that is stored with it there reliably? If you could just give me a super quick breakdown of what EWR does exactly I would greatly appreciate it!
The schematic for the FEZ Spider shows that the VBAT power pin is available.
There are a number of options for wiring a power supply (battery) to the socket’s pin. In our catalog: G-Plug, Breakout Module, BreadBoard X1. The BreadBoard is useful for prototyping custom addtions.
