Introduction to mikromedia for ARM

The

mikromedia for ARM

is a compact development system with lots of on-board peripherals which allow development of devices with multimedia contents. The central part of the system is a 32-bit ARM7 microcontroller

LPC2148

. The mikromedia for ARM features integrated modules such as stereo MP3 codec,

TFT 320x240 touch screen

display, accelerometer, two USB connectors: one for communication with the microcontroller one and for ISP programming,

MMC/SD card slot and other. Mikromedia is compact and slim, and perfectly fits in the palm of the hand, which makes it convenient platform for mobile devices.

5. Programing with JTAG programmer/debugger

Figure 5-1: Enabling

JTAG using jumper

Besides In-System programming mikromedia for ARM supports

JTAG programming

and debugging interface. In order to use it, you have to

solder 2x10 header

to the JTAG connection pads on the back side of your mikromedia board. It is also necessary to solder and set the

JTAG jumper,

located right next to the JTAG connector (Figure 5-1), in order to enable this type of programming.
