3.1.5 Programming interface (J5, SW1)
1) After shorting J5, BOOT0 signal will be activated. In this moment, if users press SW1 they
are able to use software “STMicroelectronics flash loader” (Made in ST) to write MCU’s flash
(For WIZ-SM10, users usually use “STMicroelectronics flash loader” to upload UART_boot or
Network_boot firmware file).
2) Pin SW1 is connected with SW_INPUT. When users press SW1, SW_INPUT pin goes low.
3) When J5 is in normal situation (non-short situation), turn on power and then uploaded
UART bootloader will run. This bootloader firstly check whether SW_INPUT is low. If it is low,
application firmware update menu is displayed and you can update the firmware using serial
port. That is to say,
keep press SW1 and then press SW2 to reset system.
3.1.6 SPI interface
J14 shows the circuit of SPI interface. GPIO0 pin is the CS pin which is low active.
3.1.7 Serial interface
Through corresponding RS232 transceivers, UART1 and UART2 connect with P1 and P2 DB9
interface respectively. Besides basic TX and RX communication, RTS and CTS are also
available as long as making the best of I/O. WIZ-SM10 base board provides UART1’s signal
interface, as shown in picture below. By that, UART1 can be used for other purpose, such as
I/O.
If users would like to use TTL level UART signal, please short the 2
JP3, JP4, JP5 and JP6 respectively. For RS232 level UART signal, please short 1
in jumpers JP3, JP4, JP5 and JP6 respectively.
