== AmFmCodes ==
 +
These are 32-bit values used by the Joy-Con firmware to represent combinations of amplitude/frequency pairs for vibration.
 +
 +
=== Unpacking ===
 +
The Joy-Con firmware receives vibration data packed as [[#VibrationAmFmPackTag|VibrationAmFmPackTag]] from output reports. Depending on the packing format, these tags are then converted to an array of AmFmCodes as follows.
 +
 +
==== AmFm5BitCodes ====
 +
Converted from [[#VibrationAmFmPackFormatOne|VibrationAmFmPackFormatOne]], [[#VibrationAmFmPackFormatTwo|VibrationAmFmPackFormatTwo]] or [[#VibrationAmFmPackFormatThree|VibrationAmFmPackFormatThree]].

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con is the name for the Switch's primary game controllers. The Joy-Con are internally called Sakyo (Left) and Ukyo (Right).

Hardware

Sakyo

Component Description
SoC Broadcom BCM20734
IMU STMicroelectronics LSM6DS3H
PMIC Texas Instruments BQ24072
Storage Macronix International MX25U4033E 4 Mb CMOS Flash

Ukyo

Component Description

Colors

HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.
