A set of additional non-official demo projects for QmTech
Cyclone IV
Core Board
(EP4CE15F23C8
).
For testing RS232
QuickRS232
module
was designed project SerialPortEcho
. This project receive bytes from serial port (COM
) that is configured in following mode - 115200 bit/s, 1 stop bit, even parity, no flow control
. This project do following: receive byte, add + 1 and send it back
.
You could use our application Zerial
to work with RS232
:
CLK
- global clock - already on the board -> DIFFCLK_1P
(T2
)RX
- RS232
RX
line - connected to U8
20 pin
-> IO_AB19
TX
- RS232
TX
line - connected to U8
22 pin
-> IO_AB20
RTS
- we don't USE it in this demo because simple TTL
to RS232
converter, but anyway we connect it to U8
24 pin
-> IO_Y21
CTS
- we don't USE it in this demo because simple TTL
to RS232
converter,
but anyway we connect it to U8
26 pin
-> IO_W21
RX_LED
- connect it to D5 LED
-> DIFFIO_L2P
(E4
)TX_LED
- don't have on board free LED
, therefore just out it to pin 30 of U8
(IO_U21
)Additionally RS232-to-TTL converter must be attached to power supply line and ground, that also could be taken from U8
:
3V3
- Any pin from (3, 4)GND
- Any pin from (1, 2, 61, 62)is under development....
is under development....
