Hello,
I'm using the FTDI232 breakout behind an ESP32-CAM board.
I want to plot a set of data in the IDE serial plotter tool but because of the 4kbytes input buffer, as far as I understood, plotting is jerky.
Before I was using ESP32-VROOM, don't know which serial driver is implemented, without any jerk.
Is it possible to prevent this?
Regards,
Alain
how this fact prevents you from using the plotter?
Where did you get this impression? An FT232R chip (or cable) does NOT have a "4k buffer" anywhere.
Thanks to both of you and sorry, the problem came from the sender.
The FT232 has a 256b buffer... but the fancier FTDI modules do have a larger buffer. But the usage of that buffer is just so that you computer can be tied up for longer before you lose data, it still sends the whole thing at the next transaction.
If you need the fastest response time on any FTDI adapter, you need to set the latency timer to 1ms, it defaults to 16 to reduce CPU usage. (this was encountered with SerialUPDI, where it caused the upload speed to be limited to IIRC under 200bytes per second initially (up to a few k once the godawful code we took from microchip at their instistence), but a nearly 16:1 improvement was realized by device manager > COM ports -> Select the FTDI device, and under advanced options there's somewhere to change that,
