I tried to get a Serial-USB-Converter working on my ChipworkX-System. I tried my FTDI-Converter without any problems (thats a real Serial-USB-Converter).
Afterwards I tried to use a device (optical interface to a Smart Meter and a RS485 converter with the same chip) to get it working with my board - but it does not work. The devices have a “Silicon Labs CP210x USB to UART Bridge”-Chip inside. The PC knows it as this type and offers a COM-Port. I tried sending/receiving with PC without any Problems (300 Baud, 7 databits, 1 Stopbit, Even Parity, No Handshake).
After connecting the SiLabs-Device to the ChipworkX and tried sending with the same method as the FTDI-Chip, but an other device (the device is added the same way as in the sample at GHI Librabry Documentation). But this does not work! I can see, that the optical device is sending some data (infrared is sent), but I do not get data at the other device.
What could that be? Is there a problem with the baudrate (300) using SiLabs? Does it not work with the choosen settings? I don’t know what to try next to get it working…
Thanks in advance
