This is an application example using ST Nucleo F103 board.
|
|
|
|
SB62 and SB63 should be soldered to connect PA2 and PA3 to CN10
|
|
connector.
|
|
|
|
ST-Link/V2's TX and RX are disconnected (by removing SB13 and SB14).
|
|
|
|
Smartcard can be connected, by using USART3_TX for I/O and USART3_CK
|
|
for CLK, PB6 for Vcc, PB8 for Vpp, and PB9 for RST.
|
|
|
|
|
|
NOTE:
|
|
|
|
Using the USB CDC-ACM for serial communication is a kind of wrong,
|
|
because it's designed for modem; In the protocol, we have no way to
|
|
control the CTSRTS signal.

TODO:
|
|
* Use of DMA for serial communication
|
|
* RS-232 support: GPIO with DTR (out), DCD (in), DSR (in), RI (in)
|
|
* serial config setting of CTSRTS?
|
|
By vendor specific control?
|
|
* stats report control
|
|
By vendor specific control?
|
|
* Half-duplex support
|
|
* Support of other communication mode: IrDA, etc.
