Texas Instruments TM4C123G LaunchPad

Finally received my USD12 TM4C123G evaluation kit last week after one month. I think this evaluation kit replace the Stellaris LM4F120. This low cost starter kit really pack a lot of punch with 32bit Arm Cortex M4 CPU and 256Kb program memory and 32kb SRAM running at 80MHz. The peripheral on this CPU is massive if compared to the ATMEGA328 used in the Arduino Uno. Both board have about the same size. Below is a comparison table between Tiva C series and Arduino Uno:

	Arduino Uno	Tiva C Launchpad
CPU	Atmel ATMEGA328 8-bit	TM4C123G 32-bit (2x)
Price	USD29	USD12
Flash memory	32Kb	256Kb
RAM	2Kb	32Kb
EEPROM	1Kb	2Kb
Clock (max)	20Mhz	80Mhz
IO voltage	5V	3.3V (5V input tolerant)
Digital IO	14	43
Analog input	6 10-bit	2 1-MSP 12 bit
SPI	1	4
Serial port UART	1	8
Ext int	2	43 (71 int)
PWM	6	16
I2C	yes	yes (6)
USB 2.0  OTG	no	yes
Quadrature encoder	no	yes
CAN bus	no	yes
Analog comparator	no	yes
Temperature sensor	no	yes
Watchdog timer	no	yes
RTC	no	yes
DMA	no	yes
User LED	1	1 (3 colors)
User button	0	2

Getting started on this board is very easy with Arduino like IDE called Energia. This board is not yet displayed under the supported hardware, but it work just fine with the LM4F120 selected.

Below is the board connected to the Nokia LCD5110 running sample program from

The available library is still not as much as Arduino, but I hope it will continue to be ported. I wish to see the Arduino's TVout library being ported to this board, as with the 32K RAM and a lot of horsepower, much higher resolution can be achieved.
