In the previous post , I used it in continuous sample mode. I took 1 second worth of samples, in 860 samples per second mode. In this post, I average those samp...en-USTelligent Community 12RE: Average bulk samples from Data Acquisition Board for Pi Pico with C++ STLhttps://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/average-bulk-samples-from-data-acquisition-board-for-pi-pico-with-c-stlThu, 14 Dec 2023 22:27:54 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:826761f3-c423-4c2c-959d-a0a92bbe9ad9Jan Cumps0<p>Create an array of voltages (double) from an array of samples (uint16_t):</p> <div> <div><span></span></div> [embed:dc8ab71f-3b98-42d9-b0f6-e21e02a0f8e2:3f0f6331-fb3a-480d-b64b-fcf8c4b0e883:type=c_cpp&text=%20%20%20%20%2F%2F%20convert%20every%20value%20to%20voltage%0A%20%20%20%20double%20volts%5BSAMPLES%5D%3B%0A%20%20%20%20std%3A%3Atransform%28std%3A%3Abegin%28buf%29%2C%20std%3A%3Aend%28buf%29%2C%20std%3A%3Abegin%28volts%29%2C%0A%20%20%20%20%20%20%20%20%5B%5D%28uint16_t%20u%29%7B%20return%20to_volts%28BOARD0%2C%200%2C%20u%29%3B%20%7D%29%3B]</div><img src="https://community.element14.com/aggbug?PostID=27329&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">RE: Average bulk samples from Data Acquisition Board for Pi Pico with C++ STLhttps://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/average-bulk-samples-from-data-acquisition-board-for-pi-pico-with-c-stlTue, 12 Dec 2023 20:33:33 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:826761f3-c423-4c2c-959d-a0a92bbe9ad9DAB0<p>Nice update Jan.</p><img src="https://community.element14.com/aggbug?PostID=27329&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">RE: Average bulk samples from Data Acquisition Board for Pi Pico with C++ STLhttps://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/average-bulk-samples-from-data-acquisition-board-for-pi-pico-with-c-stlTue, 12 Dec 2023 15:10:13 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:826761f3-c423-4c2c-959d-a0a92bbe9ad9shabaz1<p>Hi Jan,</p> <p>Very neat, STL is an elegant problem-solver.
