I study the different keyboard technologies and I have noticed that on membrane keyboards there are no diodes to prevent ghosting. From what I understand:
Can you confirm if I just? ^^
So I looked for open source projects of this type of membrane keyboard but I didn't find anything. (Which doesn't surprise me, because there are a lot of disadvantages with membrane keyboards.) But I still thought I would find a keyboard that would take this type of circuit without diodes.
So, do you know where I can find this type of circuit, a matrix of switch without diodes for keyboard?
Thank you :)
