Re: Save As CSV for 2 million samples

Hello, I just spent two hours tweaking PicoScope software settings with 5 MS captures, because no matter what, I could not get more than 1024^2 (1M) samples to the text formats. Such an undocumented (is it documented somewhere?) feature is a terrible idea, I was just going to post a new problem topi...

Re: Fast Streaming Mode in C for 2204 and 2205

Hello, I am still very much confused how the ps2000_get_streaming_last_values(), the user-provided callback, overview buffers and fast streaming interact. This would definitely need a more thorough treatment in the programmers manual. For example, let's say I want to stream 1 gigabyte of data at 2MS...
