Yes I think it will work but will require some code changes from VGA output to DVI output. You can find a couple of videos on my channel for how to get HDMI or DVI output from a Pico. They may be helpful.

Thank you! @@robingrosset6941

Thanks for the comment. In a server, which is where this card normally belongs the card has no fans its cooled by airflow through the server chassis. The main thing is to ensure the card and each GPU is cooled, with this delta fan it is really overkill, these fans at full speed will lift off a desk by themselves. Its a bit too much cooling. I have tried 2 fans together and the issue comes back to where will the hot air exit the card. By design of the cooling fins the hot air flows over one GPU and then over the other there is usually a temperature increase over the 2nd GPU. You see in the video one GPU is 48 degrees C the other 54 degrees C. This is normal for these cards in server environments. There are some examples of overheating cards and normal cards at the NVIDIA forum link google "tesla-k80-overheating 38690" The temperatures in this video are well below the thermal throttling levels. If you look at NVIDIA SMI screen shot in the video you'll see the GPUs are loaded up 50% and 30% But notice GPU RAM usage is 100% on both GPUs.. so they are working hard and at the RAM limit. RAM limits are often the big factor in why folks use these GPUs 10:52 nvidia-smi 100% RAM used. Its normal for CPUs to work hard pushing data to the GPUs, but it does depend on the workload. This test is CPU and GPU intensive because I am running 8 parallel machine learning workloads and an element of this workload is CPU bound because its displaying the OpenAI Gym Space Invaders user interface at high speed. In terms of longevity for this setup I just took a K80 out of a machine after 3 years and its still running fine.

@@robingrosset6941 got both , M40 single eCPU and k80 dual , full load on image generate they stay under 70 temp with 2 fans like you did on this video

Yes you can. So inside the interrupt handler there is a call to a function pwm_set_gpio_level (uint gpio, uint16_t level). the second paramter is the level and this is from the WAV_DATA so you can setup the WAV_DATA to be 16 bit integers uint_16_t instead of 8 bit . It should work fine. Do you have a 16 bit sample you want to play as 16 bit or is it that you want to covert the 16 bit sample to 8 bit? The reason for this being 8 bit to begin with was to reduce the memory size needed to store the WAV data and make it more compact. But you can use 16 bit its just your sample memory with twice as big.

​@@robingrosset6941 I tried this sort of thing... int offset = wav_position>>3; uint16_t c = (WAV_DATA[offset + 1] << 8) | WAV_DATA[offset]; int16_t signedSample = (int16_t)c; uint8_t pwmOutput = (uint8_t)((signedSample +32768)); pwm_set_gpio_level(AUDIO_PIN, pwmOutput); wav_position+=2; But it only makes a horrible noise. The PCM data is saved as 16bit lsb first.

After experimenting a bit, it seems impossible to have any better than 12bit pwm for audio, anything higher makes too much noise, it seems it can't do the timing properly.@@robingrosset6941

This phone was connected to a VOIP terminal over the internet in my house but it would also work with a telephone network directly designed to use tone dialing. Pulse dialing no longer works in many countries.

Hi, did you find any solution for install a k80 in Ubuntu ?
