im new to arduino, with programming experience in computers.
Question 1: Arduino is fine for me. Dont see the reason to make a new board on my own and start programming it without arduino bootloader. Is it "legal" and possible tho to ask a manufacture to develop a custom board for me "arduino ready"(flash bootloader) and use it commercially?
Question 2: My device needs to be operated from distance but due to security related reasons i wont it to be as much secure as possible. Checking all those key fobs online SC2262 and more i found out that there are allready libraries with someone not even experienced can read the codes etc. Even rolling codes isnt that secure nowadays. Would it be better to use the tiniest arduino board with an rf transmitter to do the encryption on my own and then send the command to my main device?
hi mate. i appreciate your answer to my question 2. what about question 1?
regarding my second question and your concern, isnt it better to have my own ecnryption instead of a very much used chip one where anyone can download the libraries etc? thought yes but just asking other people to see what do you guys think . would it make sense to use a tiny arduino on every key fob or its too much?
UKHeliBob:
Why do you assume that spycatcher is a guy ?
I think that an apology is in order.
Be careful with your conduct or you may be subject to sanctions
excuse me, when did i say he/she is guy gay bi trans or whatever? and why do i care? i said you guys tell me what do you think. to me "you guys tell me.." its like you people tell me. why dont you try speak my language to see how well you will do it? lol anw
spycatcher2k:
Possibly too much! I would use the smallest microcontroller with enough IO & Flash/RAM/EEPROM to do the job. An ATTINY 45/85 may well do the job.
thanks for that. but if i dont use an arduino that means i need to make the whole pcb on my own.like resistors and stuff right? not just an ATTINY microcontroller
spycatcher2k:
Yes, but if you use any libraries in your code, their MAY be limitations on use in commercial devices. If you are not going to have updatable firmware, you don't even need a bootloader.
if i dont use bootloader then it means i cannot install my code to the device without usb right? and in that case ill need a programmer right?and ill need to write the code in an other studio like amtel and convert it to hex or something. am i wrong?
