This is an example of using AddressIntercept technology to control microcontroller periphery from a host PC. The example tunes periphery of microcontroller STM32F103C8 , namely, UART1, UART2, DMA and GPIO LED (PC13 pin). Then UART1 sends byte message and UART2 receives it using DMA. Also the led blinks. At the end, received and sent message are checked.

Here ​Standard Peripherals Library​ is applied for high-level interaction with MCU periphery. Thanks to AddressIntercept , we can use this MCU library on a host PC. There is nothing that can prevent linking any library from the host PC.

My test stand

The green board is a Linux machine where OpenOCD server was ran. You can run an OpenOCD server on host PC if you use another local USB JTAG/SWD adapter (example st-link, jlink, etc) The blue board is a bluepill. I connected Tx UART1 (PA9 pin) with Rx UART2 (PA3 pin) using the white wire.

Let's build and run this example... My host PC is Ubuntu 16.04 64-bit and the test stand above (JTAG/SWD adapter and prepared STM32F103C8 (PA9 pin connected to PA3 pin).

А simple way:

1. Download pintool v3.7
2. Unpack archive
3. cd pin-3.7-97619-g0d0c92f4f-gcc-linux/source/tools/
4. git clone [email protected]:ser-mk/AddressIntercept.git
5. cd AddressIntercept
6. make TARGET=obj-ia32 # If you have 64-bit system, need to install some 32-bit packets
7. git clone [email protected]:ser-mk/AddressIntercept-example-UART-DMA.git
8. cd AddressIntercept-example-UART-DMA
9. make
10. cd - # to pin-3.7-97619-g0d0c92f4f-gcc-linux/source/tools/
11. mkfifo in.fifo out.fifo
12. python3.5m OCDclient.py -ip $IP_YOUR_OPENOCD_SERVER &
13. ../../../pin -t obj-ia32/addrIntercept.so -- AddressIntercept-example-UART-DMA/test.elf

and we'll have:
