    We want to develop a small PCB containing 2 parts only : 1 x Cypress PSOC 3 , 1 x Atmel memory. The cypress mcu must grab data from an external source and save it to atmel. Looking for experienced people that can deliver the job fast. You must have access to a lab with all the tools you need for prototype assembly, oscilloscope, etc If you have the cypress programmer already, it would be a +. Thanks

    Hello coders! If you don't know what an ATMEL AVR MCU is please stop reading now! I need a function to convert from geodetic (latitude longitude) to MGRS (Military Grid Reference System) coordinates using the WGS 84 geodetic datum ellipsoid. It's to be part of another project that reads GPS data. I will pass your function the lat/lon (as extracted from a NMEA stream) and get back the MGRS (precision level 1 m). I want plain C that will compile with the WINAVR GCC tools for an ATMEL AVR. Eventually to run on a MEGA1284p - so limited RAM and speed (~1.84Mhz) Also limited flash - some Kbs not scores of of them though (optimisation is on).

    Seeking a wireless network developer who is comfortable with the ANT protocol and implementation on Nordic chips (ex. nRF24AP2) controlled by Atmel AVRs (ATMega family). Specific need is the C code to be compiled for the AVR that will establish wireless communication via the Nordic transmitters. The network will consist of two transmitting nodes and a single receiving node. The receiver will be connected to a computer USB port through an FTDI chip. This receiver and associated hardware and software are completed. The AVRs will send a single byte of data to the Nordic transmitters at ~100 bps (or other very low bitrate), which will then be transmitted to the receiver and fed to the USB port. The receiver must be able to collect both streams of data simultaneously. Battery conservat...

    ...Arduino Atmel ATMega's I want some one who is, to port the code over. For someone who has the relevant experience I expect this to be an easy port and the code does not necessarily have to work! I have several arduino projects lined up, so this could be the start of a good working relationship. See here for code examples...

    CPU: Nuvoton NUC745 (also referred to as Winbond W90N745) ARM7 Platform: uClinux 2.4.20 with romfs filesystem Wifi chip: VIA VT6656 (device driver here: ) Camera: Vimicro ZC0300 series (device driver possibly here: ) The camera and wifi devices are connected to the processor via USB ports. The customer needs porting of device drivers for the camera and wifi devices under uClinux 2.4 on a NUC745 based board. A BSP with the 2.4 kernel will be provided. There are some open source device drivers to download, but they are often for newer Linux kernels and/or do not work for an ARM platform. You will need to fix the existing drivers to work under the given platform. (Some hardware control through software will possibly
