Firmware Architecture
5.1
Firmware Architecture Diagram
The FW subsystem architecture is shown as the Figure 8. There are 3 layers in subsystem:
1.
Library Layer: This layer is a constant area. User must not change it. It provides all units’ driving functions, such
as GPIO driving function, timer driving function, UART driving function, etc. This layer is separated as 2 sublayers: driver level and middleware level. For driver level, it directly operates the registers of the MCU. For
middleware level, this layer implements adopted code (SD lib/fatFS/audio codec).
2.
Module Layer: This layer is the highest layer of the system; it integrates the low level function and serves the
system as the API (i2c, uart, audio, misc).
3.
App Layer: The main function of the system is achieved by this layer

Lab Principle and Instructions
1. The function of the base timer can be set to 16-bit PWM timer. When triggered, the 16-bit PWM timer starts
decrementing from the cycle set value. First, it outputs a LOW level pulse. When the 16-bit down counter
matches the value set in the PWM Duty Set Register, the output inverts to the HIGH level. Then, the output
inverts again to the LOW level when a counter underflow occurs. This can generate waveforms with any cycle
and duty. (More details to refer to FM0+ Family Peripheral Manual Timer Part). So set PWM duty to control the
total current into LED
2.
The Figure 9 shows that PIN22, PIN23 and PIN24 are selected to control RGB LED.
The PIN22 has TIOA3_1 function at the output pin of BT ch.3 TIOA.
The PIN23 has TIOA4_1 function at the output pin of BT ch.4 TIOA.
The PIN24 has TIOA5_1 function at the output pin of BT ch.5 TIOA.

Lab Principle and Instructions
1. The Figure 20 shows that CMSIS-DAP module can receive/send characters from/to PC and then forwards data
to FM0+ with UART communication
Figure 20. CMSIS-DAP Block
2.
The multi-function serial interface has the following characteristics
a.
UART0 (Asynchronous normal serial interface)
b.
UART1 (Asynchronous multi-processor serial interface)
c.
CSIO (Clock synchronous serial interface) (SPI can be supported)
d.
LIN(LIN bus interface)
e.
I2C (I2C bus interface)
Firstly, set multi-function serial interface mode to switch UART mode.
3.
UART is a general-purpose serial data communications interface for asynchronous communications (start/stop
synchronization) with external devices. It supports a bi-directional communications function (normal mode) and a
master/slave type communications function (multi-processor mode: both master and slave modes supported). It
also has transmitted/received FIFO (More details to refer to FM0+ Family Peripheral Manual Communication
Macro Part).
4.
The Figure 21 shows that SOT0_0 and SIN0_0 are selected to communicate with CMSIS-DAP.

Lab Principle and Instructions
1. The KXCJK is a tri-axis ±2g, ±4g or ±8g silicon micro-machined accelerometer. The sense element is fabricated
using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the
principle of a differential capacitance arising from acceleration-induced motion of the sense element, which
further uses common mode cancellation to decrease errors from process variation, temperature, and
environmental stress.
The Kionix KXCJK digital accelerometer has the ability to communicate on the I2C digital serial interface bus.
This allows for easy system integration by eliminating analog-to-digital converter requirements and by providing
direct communication with system micro-controllers.
2.
I2C is a two-wire serial interface that contains a Serial Clock (SCL) line and a Serial Data (SDA) line. SCL is a
serial clock that is provided by the Master, but can be held low by any Slave device, putting the Master into a wait
condition. SDA is a bi-directional line used to transmit and receive data to and from the interface. Data is
transmitted MSB (Most Significant Bit) first in 8-bit per byte format, and the number of bytes transmitted per
transfer is unlimited. The I2C bus is considered free when both lines are high. The I2C interface is compliant with
high-speed mode, fast mode and standard mode I2C standards

4.
The Figure 6 41 shows that SOT2_2 and SCK2_2 are selected to communicate between FM0+ MCU and
KXCJK-1013. The KXCJK’s Slave Address is comprised of a programmable part and a fixed part, which allows
for connection of multiple KXCJK's to the same I2C bus. The Slave Address associated with the KXCJK is
000111X, where the programmable bit, X, is determined by the assignment of ADDR (pin 7) to GND or IO_Vdd.
So the Slave Address associated with the KXCJK is 0001110.

Lab Principle and Instructions
1. FatFs is a generic FAT file system module for small embedded systems. The FatFs is written in compliance with
ANSI C and completely separated from the disk I/O layer. Therefore it is independent of hardware architecture.
Petit FatFs module is also available here.
Features:
Windows compatible FAT file system.
Platform independent, Easy to port
Very small footprint for code and work area
Various configuration options:
Multiple volumes (physical drives and partitions)
Multiple ANSI/OEM code pages including DBCS.
Long file name supported in ANSI/OEM or Unicode.

Document No. 002-04393 Rev.*A
40
FM0+ Starter Kit 32-Bit Microcontroller
RTOS support.
Multiple sector sizes supported
Read-only, minimized API, I/O buffer and etc
The picture shown below is a typical configuration of the embedded system with FatFS module.
Figure 65. Typical configuration of FatFS module
2.
Disk I/O Interface:
Since the FatFs module is completely separated from disk I/O layer, it requires following functions to access the
physical media. When OS related feature is enabled, it will require process/memory functions in addition.
However the low level disk I/O module is not a part of FatFs module, so that it must be provided by user.
3.
As Berrypecker doesn’t have the specified SDIO interface, choose the SPI mode to drive the SD card. It contains
data read and write access on SD card. It will supply the user three functions, including SD card initialization, SD
card read and SD card write.
4.
The PDL middleware of FM0+ PDL implements the middleware SD card driver(SPI mode), so you only need to
modify the requested SPI channel
5.
The Figure 6 59 shows that SOT4_2, SIN4_2 and SCK2_2 are selected as SPI interface to communicate
between FM0+ MCU and SD card. P04 is selected as CS signal

Lab Principle and Instructions
1. I2S, known as Inter-IC Sound, Integrated Interchip Sound, or IIS, is an electrical serial bus interface standard
used for connecting digital audio devices together. It is used to communicate PCM audio data between
integrated circuits in an electronic device. The I2S bus separates clock and serial data signals, resulting in a
lower jitter than is typical of communications systems that recover the clock from the data stream. Despite the
name, it is unrelated to the bidirectional I²C bus.
2.
Codec module is developed to transmit audio data and control the transmission flow. To achieve this purpose,
I2S and I2C bus protocol must be supported. Audio data transmission will be powered by I2S (inter-IC sound)
bus protocol. This bus has only to handle audio data, while the other signals are transferred separately. I2S is a
3-line serial bus and consists of a line for two-multiplexed data channels, a word select line and a clock line. The
picture below is the simple system configurations of I2S bus. Both transmitter and receiver could be master
mode. In other words, both transmitter and receiver can supply clock and word select signal.
