Channel

Goal/Scope

Proposed Testing Strategy

Main Channels

SPI (Eric)

Tester Code (Arduino):

Target Code (ZP3): (tick)

Additional Notes:

Can transmit and receive data from and to a device.

Can use chip select/enable line to selectively communicate with multiple peripherals.

Send sample SPI signals through the channels and verify output using Saleae Logic Analyzer.

UART

SPI loopback connection should be able to test that transmit & receive work. (connect MOSI to MISO) and send random values through it, receiving what is sent. The sent value and received value should match if the SPI is working properly.

UART (ethan)

Tester Code (Arduino): (tick)

Target Code (ZP3): (tick)

Additional Notes:

Can transmit and receive data from and to a device.

Send sample UART message through each channel and verify output via terminal.

Or send sample UART sequence through each pinout and perform Saleae analysis.

from testing board and see if target can echo the message back to the EVB.

I2C (ethan)

Tester Code (Arduino):

Target Code (ZP3): (tick)

Additional Notes:
May need a third wire change just for I2C

Can transmit and receive data from and to a device.

Send sample I2C sequence through each pinout and perform Saleae analysisSimple I2C echo task between boards.

PWM (Eric)

Target Code (ZP3):

Additional Notes:

None.

PWM DMA (Ethan)

Target Code (ZP3): (tick)

Additional Notes:

Figure out how to work with an oscilloscope.

Can configure the PWM TIMS to generate PWM signals.

Basic: Configure PWM settings. Connect to oscilloscope. Inspect/analyze PWM signal.

DMA: Configure PWM settings (using DMA method). Connect to oscilloscope. Inspect/analyze PWM signal.

⭐ Test by sending PWM signals to on-board LEDs and confirm functionality by visual inspection (much less rigorous than oscilloscope analysis).

GPIO(Ethan)

GPIO (ethan)

Tester Code (Arduino): (tick)

Target Code (ZP3): (tick)

Additional Notes:

GPIO_3 is set as an input GPIO. ZP3 should be able to detect high/low but doesn’t have to drive high/low. It has a unique test. The Arduino will set the pin high and if ZP3 can detect it properly, it will drive GPIO_1 high and Arduino will output the pass/fail.

Syncing the timings will be tricky. May need to add delays between GPIO R/W.

Can toggle on and off.

Pull each GPIO pin up/down.

Options to check functionality:

  1. Saleae (time consuming for simple GPIO)

  2. Connect LED to each gpio pin and drive high → low.

  3. Drive GPIO pins high and output a simple message to a terminal if a HIGH signal was read from each GPIO pin confirming it was successfully pulled HIGH/LOW.

ADC

Connect GPIO pins of testing board to ZP3 board. ZP3 pulls pins high/low and testing board reads pins to see if they are the right state. Possibly do the other way around too.

ADC (ethan)

Tester Code (Arduino):

Target Code (ZP3):

Additional Notes:

TODO: Find a reference voltage-digital output to validate correctness of output.

Varying analog input is converted to a digital binary output.

Connect potentiometer/voltage source to ADC in channel. Vary voltage input . Output binary values to terminal?MicroSDand observe digital outputs.

MicroSD (eric)

Target Code (ZP3): (tick)

Additional Notes:

None.

Read/Write data to the SD Card.

Write:

Create text file, write to the text file, plug the SD card into a computer and confirm that the test text file has been created and written to.

Read:

Read from a the test file. Check size of input variable to see that the size of the file data and variable matchOutput data to terminal.

OR

Attempt to read known data from a text file. Pass through an assertion or if statement.

On-board LEDs (eric)

Target Code (ZP3):

Additional Notes:

None.

Can light up.

Run simple blink test code on each on-board LED.

MISC

GPIO Interlock

Pins:

  • PF2 (GPIO_IL_D) (tick)

  • PF3 (GPIO_IL_C) (tick)

  • PG6 (GPIO_IL_B) (tick)

  • PG7 (GPIO_IL_A) (tick)

GPIO interlock, should be read high (3V3) to ensure interface board is properly connected.

Read the pins.

uSD_Detect (tick)

Pin: PF11

Pin low when SD card is inserted and high when SD card slot is vacant

This functionality was not confirmed and should be checked.

Read pin (should be low when SD card is inserted and high when SD card is empty)

PWR_SENSE

Pin: PA4 (ADC2_IN9)

Measures the voltage available to the system after power filter

Calculated using V = PWR_SENSE * 18.28395 (280k, 16.2k voltage divider)

DMM

VBAT_B_SENSE

Pin: PC2 (ADC2_IN3)

Measures the voltage of battery B

Calculated using:

V = VBAT_B_SENSE * 18.28395 (280k, 16.2k voltage divider)

DMM

VBAT_A_SENSE

Pin: PB1 (ADC2_IN16)

Measures the voltage of battery A

Calculated using:

V = VBAT_A_SENSE * 18.28395 (280k, 16.2k voltage divider)

DMM

Remaining Tasks:

  1. Write code for each functionality for testing.

  2. Flashing onto ZP3 (Message aidan bowers and ask if he has successfully flashed the zeropilot pcb with open ocd or if it would be easier to use the ST-link and how to connect).

  3. Test the testing code by performing bring-up on a zp3 board.

  4. Create user friendly confluence document with clear instructions.
