Forwarding serial data from USB to UART and vice versa: performance issue
Hi, for an NMEA-RTK-receiver, I need to forward data from UART to USB (the NMEA sentences 10 time 200 bytes a second) and at the same time data from USB to UART (the NTRIP correction data 200 bytes once per second). There are no timing requirements to the NMEA data apart from the fact, that the forw...

Re: using HTERM with RP2040
Ok, in my EARLY days as well.. :lol: I remember I put an optocouper to the RI line to detect incoming FAX.. Oh my god - I'm old! :) In fact, I was talking about µC and serial. When handshake is used today, it is used as PIO for reset or entering programming mode, altough the classic usecase may stil...

Re: using HTERM with RP2040
Finally it was totally simple: It was the handshake! OMG, how could I oversee that :roll: Normally, it's allways no handshake on a physical interface because 2 lines are less efford than for lines ;) , but the RP2040/Micropyhton obviously uses (virtual) HW handshake by default. Enabling flow control...

Re: using HTERM with RP2040
The type of a serial input is always byte, but C# simply doesn't even trigger that event. Well, yes, I also thought about a different task blocking that, especially because the USB of the RP2040 may provide different services. That's why I also tried the Zadic driver (https://zadig.akeo.ie/), but th...

Re: using HTERM with RP2040
It's not a problem of coding chars, because data is perfectly received as 8bit-ASCII e. g. with 'pqcom'.
Python works perfect on Windows as well, but not C#. C# detects the connection, opens the port, but does not receive anything (class System.IO.Ports.SerialDataReceivedEventArgs).

Re: using HTERM with RP2040
So did I - having no reaction as well.
Hterm:
- check "Hex" in "input control" window
- enter 01 (e. g. for Ctrl-A)
- press enter key

Re: using HTERM with RP2040
yes, seems Thonny and Hterm can both connect to the RPi Pico (tried with that board this time) at /dev/ttyACM0 at the same time. Of couse, it does not work...
