Suggested Hardware Requirements
The software library has been optimized to quickly compile on the NUCLEO-L4R5ZI development board stacked with MB1303 expansion board (from P-NUCLEO-USB002 package). MB1303 is composed of 2 Dual Role Ports (DRP) USB PD capable receptacles (form factor not optimized).
NUCLEO-L4R5ZI: STM32 Nucleo-144 development board.
MB1303: Board contained in P-NUCLEO-USB002 orderable package.
NUCLEO-L4R5ZI Hardware Set-up
Hardware modifications to be done on MB1312 in order to use MB1303 shield offering 2 USBPD ports based on STUSB1602 + stm32L4R5ZI:
- Remove: SB124, SB132, SB130, SB141, SB131, R39 (for 2nd port LEDs), R40 (for 2nd port LEDs)
- Close: SB145 (for 2nd port LEDs), SB146 (for 2nd port LEDs)
- Add: 38 pins connectors on both CN11 and CN12
- For Trace: connect wires between MB1303 CN2 and Nucleo CN6 (Tx-Rx)
Software Package Overview
The software library includes 8 different software frameworks (+ 3 without RTOS) already optimized to address most common application scenarios:
| # | Project | Typical Application |
|---|---|---|
| 1 | STM32L4R5_MB1303_SRC_ONLY(*) | Provider / SOURCE (power management) |
| 2 | STM32L4R5_MB1303_SRC_VDM | Provider / SOURCE (power management) + extended message support |
| 3 | STM32L4R5_MB1303_SNK_ONLY(*) | Consumer / SINK (power management) |
| 4 | STM32L4R5_MB1303_SNK_VDM | Consumer / SINK (power management) + extended message support + UFP support |
| 5 | STM32L4R5_MB1303_DRP_ONLY (*) | Dual Role Port (power management) + dead battery mode |
| 6 | STM32L4R5_MB1303_DRP_VDM | Dual Role Port (power management) + dead battery mode + extended message support + UFP support |
| 7 | STM32L4R5_MB1303_DRP_2PORTS | 2 x Dual Role Port (power management) + dead battery mode + extended message support + UFP support |
| 8 | STM32L4R5_MB1303_DRP_SRCING_DEVICE | Dual Role Port requesting PR_swap when attached in Sink or DR_swap when attached in Source |
- By default, all projects are packaged with RTOS support.
- Projects annotated with a (*) are available with and without RTOS support.
