How to use your PmodDA3 with RX62N the RX62N and the Cloud


Recommended Posts

The PmodDA3 is a single, 16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC) that operate from a single 2.7 V to 5.5 V supply for the RX62N. In order to use your PmodDA3 with the RX62N and the cloud, you have to download the correct binary to your kit which allows the PmodDA3 to connect to the cloud.

The goal of this project (Microcontroller No-OS) is to be able to provide reference projects for lower end processors, which can't run Linux, or aren't running a specific operating system, to help those customers using microcontrollers with ADI parts. Here you can find a generic driver which can be used as a base for any microcontroller platform and also specific drivers for different microcontroller platforms.




The driver contains two parts:

The driver for the AD5541A part, which may be used without modifications with any microcontroller.

The Communication Driver, where the specific communication functions for the desired type of processor and communication protocol have to be implemented. This driver implements the communication with the device and hides the actual details of the communication protocol to the ADI driver.

The Communication Driver has a standard interface, so the AD5541A driver can be used exactly as it is provided.

There are three functions which are called by the AD5541A driver:

  • SPI_Init() – initializes the communication peripheral.
  • SPI_Write() – writes data to the device.
  • SPI_Read() – reads data from the device.

im just a noob but i see cheaper ways to do this. ive also seen those SPI functions in books from the 90's....


sorry but it looks like all u are doing is ripping other people's projects, adding a few lines of http code to ur website, and renaming it marketting terms like "internet of things cloud connected device"
