21 @par Example Description
22
23 This example provides a basic communication between USARTy and USARTz using
24 interrupts. USARTy and USARTz can be USART1 and USART2 or USART2 and USART3,
25 depending on the STMicroelectronics EVAL board you are using.
26
27 USARTz sends TxBuffer2 to USARTy which sends TxBuffer1 to USARTz. The data received
28 by USARTy and USARTz are stored respectively in RxBuffer1 and RxBuffer2. The data
29 transfer is managed in USARTy_IRQHandler and USARTz_IRQHandler in stm32f10x_it.c file.
30
31 USARTy and USARTz configured as follow:
32 - BaudRate = 9600 baud
33 - Word Length = 8 Bits
34 - One Stop Bit
35 - No parity
36 - Hardware flow control disabled (RTS and CTS signals)
37 - Receive and transmit enabled

50
51 - This example runs on STM32F10x Connectivity line, High-Density, High-Density
52 Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density
53 and Low-Density Value line Devices.
54
55 - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
56 Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line),
57 STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density)
58 evaluation boards and can be easily tailored to any other supported device
59 and development board.
60 To select the STMicroelectronics evaluation board used to run the example,
61 uncomment the corresponding line in USART/Interrupt/platform_config.h file
62
63 - STM32100E-EVAL Set-up
64 - Connect a null-modem female/female RS232 cable between CN10 (USART1) and
65 CN5 (USART2).
66 @note Make sure that jumper JP5 is not open.
67
68 - STM32100B-EVAL Set-up
69 - Connect a null-modem female/female RS232 cable between CN10 (USART1) and
70 CN9 (USART2).
71 @note In this case USART2 Tx and Rx pins are remapped by software on PD.05
72 and PD.06 respectively.
73
74 - STM3210C-EVAL Set-up
75 - Connect USART2 Tx pin (PD.05) to USART3 Rx pin (PC.11)
76 - Connect USART2 Rx pin (PD.06) to USART3 Tx pin (PC.10)
77 @note In this case USART3 Tx and Rx pins are remapped by software.
78 Make sure that jumpers JP19 and JP18 are open.
79
80 - STM3210E-EVAL Set-up
81 - Connect a null-modem female/female RS232 cable between CN12 (USART1) and
82 CN8 (USART2).
83
84 - STM3210B-EVAL Set-up
85 - Connect a null-modem female/female RS232 cable between CN6 (USART1) and
86 CN5 (USART2).
87 - In this case USART2 Tx and Rx pins are remapped by software on PD.05
88 and PD.06 respectively.

90 @par How to use it ?
91
92 In order to make the program work, you must do the following :
93 - Copy all source files from this example folder to the template folder under
94 Project\STM32F10x_StdPeriph_Template
95 - Open your preferred toolchain
96 - Rebuild all files and load your image into target memory
97 - Run the example
98
