deprecated: BPT is renamed to PHiLIP, more information found here

How To Run

Connect the DUT (device under test) I2C0 to the BPT (bluepill tester). Information for BPT setup can be found here.

Example Test With Nucleo-F401RE

1. Flash the periph_i2c firmware on the nucleo-f401 with make BOARD=nucleo-f401 flash in the periph_i2c directory
2. Connect the BPT to the cpu using a USB to Serial converter
   (BPT IF_TX = PA9)
   (BPT IF_RX = PA10)
3. Connect the BPT to the DUT
   (DUT SCL/D15 <=> BPT SCL1/PB6)
   (DUT SDA/D14 <=> BPT SDA1/PB7)
   (DUT NRST <=> BPT PB1)
   
4. Run the test.py from the periph_i2c/tests directory (with various options)
   python test.py for basic tests with autoconnect
   python3 test.py for python 3
   python test.py --log=DEBUG to see all debug messages
   python test.py --dut_port="/dev/ttyACM0" to specify the port
   python test.py --log=DEBUG --dut_port="/dev/ttyACM0" --dut_baud=9600 --bpt_port="/dev/ttyACM1" > nucleo-f401_test.txt for all the fix'ns
   

Flags

--log=DEBUG -> allows for debug output
--dut_port -> the port name of the DUT
--dut_baud -> the baud rate of the DUT
--bpt_port -> the port name of the BPT

Notes

• If no serial connection to the BPT the test should still be able to run, it just will not be able to reset.
• Connect the SDA, SCL and if possible the DUT reset pin.
• Autoconnect may work if no ports are specified.
• Default baud rate is 115200
