I've also tried the handful of suggestions over in the forum ( setTimeout(0), forcing a Serial.read() etc. The behavior leads me to believe that the bug occurs when a USB RX buffer (always 64 bytes) is full or runs over either (1) the next buffer is not being filled correctly, or (2) the counter/index pointing to the received data is not being updated Any help would be greatly appreciated! I've been poking around in usb_serial.h/c files but not familiar enough with the codebase to make much headway. Highlights of the utility are the ease of installation (possibly with. It uses an interface similar to that of 'messenger' or 'chat' programs, with a large window that contains all received data and an edit line for typing in strings to transmit. Choose a font and text size so that you can clearly see the colors changing. ![]() Four horizontal scroll or slider bars are used for selecting the colors: red, green, blue, and opacity percentages. For example, just send 111111111111111111111111111111111111111111111111111111111111123 and it will work every time. Write a Java program named ColorChanger that uses scroll bars or sliders to select the color for a text string as shown below. Anything over that and it will show the first 64 of what was sent, and then never show anything more. ![]() Serial.begin(115200) // baud doesn't matter (native USB).įor inputs less than or equal to 63 bytes, it will echo back appropriately. ![]() Just echo back what's seen over USB serial.
