M328) to get stuck (and the USB chip still functions) the board will recover (reset and restart the program) when pressing reset button on Arduino. If EMI interference causes Arduino processor (eg. Pressing reset button on Arduino won’t fix stuck USB chip, only removing power / unplugging USB cable will gelp. If EMI interference causes the USB chip to get stuck the computer can not communicate with the Arduino anymore, however the Arduino may still work / run it’s code. short and twisted cables to motors, good grounding, snubbers where applicable). Also electromagnetic interference susceptibility will be tested, which is important for example in control and CNC applications.ĮMI susceptibility is common problem of most of the USB to TTL converter chips, but can be avoided by properly wiring and protecting your circuit (eg. I plan to do further testing with both receive and transmitt and with high data loading to determine the stability of the chip and the supplied driver. The only thing that may be problematic is that it does not report framing errors (if wrong baudrate is set), however in normal operation such errors should not occur and checking for this is mostly not implemented in software I know.
PL2303 TO USB CH340 SERIAL
RealTerm, Bray Terminal or whatever you choose to use) will show correct data only at the set baudrate on PC side, other baudrates will produce garbage data.I have done preliminary testing at standard baudrates of 600 – 256000 and the CH340 seems to preform quite well. (BEST DEALS) Consumer Electronics Buy Quality CH340 module instead of PL2303, CH340G RS232 to TTL module upgrade USB to serial port in nine Brush small. Sending data and baudrate switching is done at 1s interval. At each baudrate the program makes arduino send a baudrate in number form and then a predefined string consisting of all human readable characters. The program cycles through the preset baudrates. The following arduino code was used to test the CH340 at receiving data. I have tested the board with Arduino IDE on all of the computers and everything seems to work as it should.
PL2303 TO USB CH340 DRIVER
The driver installation on WinXP is simple and requires you just to run the supplied exe file and click a button.
I suggest you to have an antivirus running while downloading and running any executable from unknown source.
PL2303 TO USB CH340 DRIVERS
Also mac and linux drivers are available on same page. On WinXP it requires manual installation of the drivers (CH341SER.EXE available from the producers website), while on the other two versions the drivers installed automatically without any user help needed. I have tested Arduino UNO board with the CH340G and the converter on WinXP, Win7 and Win8 computers. CH340 is a USB to UART/TTL converter made by WCH (Win Chip Head ? / / The converter replaces the costlier FT232 / PL2303 / CP2102 / M16U2 USB to UART converter chips and has a Windows certified driver to avoid problems with installation. There have been many low-cost Arduino boards with CH340 converter available recently.
