Web2 hours ago · `I am facing difficulty to transfer data from Arduino IDE to VS Code via RS232 cable & vice versa. Basically, I have to transfer data from one com port to another com port. At one end it will send data & at another end it will read data. Equipments used :- 1)RS232 2)TTL converter 3)ESP32 4)Jumper wire. WebAug 15, 2002 · The ReadFile API has to specify how much data to read. Let’s say we are monitoring character arrivals and 10 characters arrive at the port. As soon as the first character arrives at the port the system will set the overlapped structure’s event object and our WaitSingleObject will return. Next we would need to read the data.

The transmission operates at 10 baud - slowly. ... If you request only 1 byte in the ReadFile call I would expect it to return within 1 character time, or 1 second in your case. That should make buffer lengths irrelevant and give you low latency. brakes how much
