SOFTWARE
- Official DEMO of LCD write, joystick and button read, for IAR EW for ARM v5.50
- Example in Olimex ODS IDE
- eLua - Lua language project build for SAM7-EX256 with GCC and OpenOCD
- Native hardware support by eCOS the anonymous eCos CVS tree has this target inside 'sam7ex256' eCos target. Here is the link to eCos 3.0 the anouncement The instructions how to install eCos 3.0 on Linux and Windows
- old demo code LCD write, Joystick and buttons read, (use only if the latest official demo doesn't seem to work) for IAR EW-ARM 5.50 Note: NOKIA6610 comes with two type of controllers, the difference is in the label on the display GE8 and GE12, this project handles both controllers, but you have to comment (#define GE12) if your LCD is GE8, separate BIN files are geenrated for download for GE8 and GE12
- TCP-IP code with FreeRTOS
- BMP-TO-ARRAY converter for Nokia 6610 LCD
- Jim Lynch's NOKIA 6610 LCD tutorial
- Ting Chen Hanson's eForth implementation for SAM7-EX256, demo bin code is available for free download
- OpenOCD + Eclipse set of projects 1.00 include flash write make file for SAM7-EX256. The complete list of projects included is here.
- Chibi RTOS - open source portable fast RTOS supports SAM7-EX256
