| This page gives an overview of using the Analog Devices Sigma Delta ADCs with Cortex-M3 ARM processor based [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EV-COG-AD3029.html#eb-overview | ADuCM3029 Cog Eval Board]]. The intended demo application shows how to convert an external sensor data into actual units and transmit them over either Bluetooth or UART link using ADIs [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EV-COG-AD3029.html#eb-overview | ADuCM3029 Cog board]] and [[https://wiki.analog.com/resources/eval/user-guides/ev-cog-bleintp1z | Bluetooth Eval board]]. The operation can be better illustrated using below diagram. | This page gives an overview of using the Analog Devices Sigma Delta ADCs with Cortex-M3 ARM processor based [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EV-COG-AD3029.html#eb-overview | ADuCM3029 Cog Eval Board]].

| The ADuCM3029 COG board is connected to Sigma Delta ADC Eval board using a [[https://wiki.analog.com/resources/eval/user-guides/ev-gear-expander1z | Gear Expander board]]. Depending upon the digital interface used on Sigma Delta ADCs, the connection could be either 4 line SPI or 3 line I2C. The connection can be done either using [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/sdp-breakout-board.html | SDP breakout board]] or by directly soldering fly wires from the ADC Evaluation board to ADuCM3029 Expander Gear board. The sample connection for the AD7124 Eval board with COG board is shown below using a fly wires. The wires are directly soldered on the Eval board, but for better connection, use the SDP breakout board: | The ADuCM3029 COG board is connected to Sigma Delta ADC Eval board using a [[/resources/eval/user-guides/ev-gear-expander1z | Gear Expander board]].
