VesiScan-Basic-firmware-test/project/ble_peripheral/ble_app_bladder_patch/fstorage.c
Charles Kwon 8129f55216 VesiScan BASIC origin: Piezo + IMU firmware initial code 
- nRF52840 + SoftDevice S140 BLE firmware
- Piezo ultrasound TX driver (2MHz, 8ch MUX)
- ICM42670P IMU 6-axis driver
- Echo AFE chain (ADA2200 + ADC121S051)
- BLE NUS command parser (mpa/mpc/mdc/mec/maa/msp)
- FDS flash config storage
- pc_firm parser and ADC driver included
