- Identify the type of PDO:
- Fixed supply PDO: Defines a fixed voltage jeung ayeuna
- Battery supply PDO: Defines a range of voltages and a maximum power
- Variable supply PDO: Defines a range of voltages and a maximum current
- Programmable Power Supply (PPS) APDO: Allows for a programmable voltage jeung ayeuna.
- Nangtukeun parameter:
- Voltage: Voltage tingkat nu PDO nyadiakeun atawa menta
- Current / power: The current (for fixed and variable PDOs) or power (for battery PDOs) the PDO provide
or request.
- Use the STM32 Cube MonUCPD GUI:
- Lengkah 1: Ensure you have the latest version of the STM32 Cube Mon UCPD application
- Lengkah 2: Connect your STM32G071-Disco board to your host machine and launch the STM32 Cube Monitor-UCPD application
- Lengkah 3: Select your board in the application
- Lengkah 4: Navigate to the “port configuration” page and click on the “sink capabilities” tab to see the
current PDO list - Lengkah 5: Modify an existing PDO or add a new PDO by following the prompts
- Lengkah 6: Click on the “send to target” icon to send the updated PDO list to your board
- Lengkah 7: Click on the “save all in target” icon to save the updated PDO list onto your board[*].
Di dieu téh urutampkumaha anjeun tiasa nangtukeun PDO suplai tetep dina kode:
/* Define a fixed supply PDO */
uint32_t fixed_pdo = 0;
fixed_pdo |= (voltage_in_50mv_units << 10); // Voltage in 50 mV units
fixed_pdo |= (max_current_in_10ma_units << 0); // Max current in 10 mA units
fixed_pdo |= (1 << 31); // fixed supply type
Example konfigurasi
Pikeun PDO suplai tetep kalayan 5 V sareng 3A:
content_copy
uint32_t fixed_pdo = 0;
fixed_pdo |= (100 << 10); // 5 V (100 * 50 mV)
fixed_pdo |= (30 << 0); // 3A (30 * 10 mA)
fixed_pdo |= (1 << 31); // fixed supply type
Pertimbangan tambahan:
- Dynamic PDO selection: You can dynamically change the PDO selection method at runtime by modifying the USED_PDO_SEL_METHOD variable in the usbpd_user_services.c file[*] .
- Evaluation of capabilities: Use functions like USBPD_DPM_SNK_EvaluateCapabilities to evaluate received capabilities and prepare the request message[*] .
