Pretty interesting and revealing this Ben Krasnow presentation. What it kind of confirmed to me is the quick transmission is with 20Mhz to get the data buffers updated, but that transmission follows the update of the display cell by cell with looking up the waveform and pushing it out. The ...
I have a char *data that is a Datagram to represent the packet I want to send in but I need to insert on that an uint8_t array. // Datagram to represent the packet char datagram[4096], source_ip[32], *data, *pseudogram; // zero out the packet buffer memset(datagram, 0, 4096...

The Swift programming language has a bunch of different integer types. The Swift integer APIs were cleaned up by an old proposal namedProtocol-oriented Integers, which resulted in a more generic way of expressing these kind of data types. ...
set the response type of that request to blob (not json, like you mentioned in the comments) on request completion (and if the response exists, so that you don't get errors like you got in the screenshot you posted!) set up the reader to read the response as a base64 dataURL and...
