I have an unusual use case for the Proxmark: I use it as a switchable 13.56 MHz field generator, to output morse code on an implant with LEDs activated by the NFC antenna. No selecting a chip, no talking to it, no nothing. Just field on and off. You can see what this is about here: https://forum.dangerousthings.com/t/flashing-morse-code-on-a-led-implant/8041
The problem is, I looked around in the Proxmark client's list of commands, but I couldn't find commands really dedicated to controlling the field. The best I could find was those:
Field on: hf 14a raw -a -p
Field off: hf 14a reader x s
They work, but they're quite slow. As a result, I have to limit the speed at which I can output a morse code message.
Any way of controlling the field more quickly?
