Hello. Interested in the question: I need to transfer information from the microcontroller via the audio port on the computer. On the microcontroller we output is what would this data need to be connected to rashema for a microphone on a PC? Right? Or can you not connect to mikrofonom entrance. And just reprogrammed the audio port on the PC to receive data. So, too, really do?
another idea was to add a microcontroller to SD memory card that would be all the testimony was preserved on it, at the end of the deposition data is sent to the computer. Tell you something ? maybe I'm in something wrong ...
View in the direction of the modulation from the old PC, which stored data on audio cassettes. Although it is strange to use the old MCS-51, SD card and transmission of sound. Now there is a normal AVR and STM with a USB controller, and the ROM chips.

You here is all chewed: do microcontroller FSK modem, connect it with the MIC input on the computer and listening to the signal, and then decodedate it. Driver there any side not feel anything, but ACCORDING to decode signal on the computer will have to write, of course. "reprogram" audio Jack is also not necessary you have your MIC input is. No matter, separate or combined.
Don't want to have fun with the encoding and decoding of data - make the connection through COM port, it's all easymode for newbies.
Want to SD card, learn to work with it as SPI and work with the file system.
If you have a diploma lit and knowledge about microcontrollers in a neighbourhood of zero, make the exchange via COM-port and do not fuck the brain, headings, typed in caps, it's rude.

clearly the second option "add a microcontroller to SD memory card" it is better and more time there are problems just with getting the sound, and, therefore, implementation of audio FSK modem is better not to Suva.
Examples with SD card sea. But since it's not specified what do Arduino/стм32 and so that I can not help. Suggest to Google under its platform. SD card Razgulay very much, "soldered 10 wires, copied from a ready example and it worked" are examples of the category are immediately, and should know who to be to not find them.
