1. Getting Started
This article guides readers through the process of installing USB to TTL drivers for a multiplexer board, including hardware preparation, driver installation, and troubleshooting tips for ensuring successful signal conversion.
2. Usage Example for Arduino-USB to TTL Conversion
Sample descripition: The multiplexer board achieve USB to TTL, micro USB interface in A as input and the TTL interface in B as output. The operation is same for USB to 232 and 485.Similarly, the reverse converter B to A is also feasible,such as 232 to USB,485 to USB, TTL to USB.
FAQ
Hi, I have been using this converter for a few weeks and works great. I am just having some issues when converting a signal from RS485 to TTL. I was having some 'framing' issues (the idle state of the line was a logic 0, when it should be a logic 1, so the start and stop bits where not being detected correctly by my logic analyzer). I noticed a jumper labeled 'RS485_RES' and decided to remove it, and the framing errors disappeared. I did not find information about this jumper in the wiki. Could you please elaborate a little on this jumper?
Hi, it is just a UART converter, it can't be reset. please check https://www.dfrobot.com/ind...
