FT232R and PICs connection - dolyshor - 2014-10-23 Hello, I have the following situation: hardware: FT232R PIC16F1938 TXD tied with RX RXD tied with TX RTS tied with MCLR CTS see below software: Win7 32, ds30Loader GUI 1.5.7, driver for FT232R v2.10.00 (I know that there is a newer version but for this chip - FT232R - it's no difference); other software or firmware are not relevant for this discussion. I have tried to write some firmware into the PIC either connecting CTS pin of the FT232R to ground or leaving it unconnected. In both situations I have been able to write correctly my firmware into the PIC regardless the settings in the GUI: a) Reset tab: manual or RTS checked; b) Basic tab\Flow control: None or Xon/Xoff or Hardware or Both. So, the recommended schematic - I mean the connection of CTS to ground - from page 21 of the main manual, October 2012 version, and the above mentioned settings are required only when we are using a true, not a virtual, COM port together with the MAX232 shifting levels chip? In that case, there is no longer needed a 5-pin connector, but a 4-pin one, to upload the firmware into the PIC. Am I right? RE: FT232R and PICs connection - Mikael Gustavsson - 2014-10-25 Hello, Only GND, Tx and Rx are required for both true and virtual com ports. Connecting CTS is not required. Connecting RTS to MCLR is not required but makes it easy to reset the PIC/dsPIC. RE: FT232R and PICs connection - dolyshor - 2014-10-26 Hello, Thank you for your answer. It is as I have expected. |
