Konfigurasi lan kode aplikasi

Kepiye carane nggawe PDO?

Mbangun obyek data daya (PDO) ing konteks USB Power Delivery (PD) melu nemtokake kemampuan daya sumber USB PD utawa sink. Mangkene langkah-langkah kanggo nggawe lan ngatur PDO:

1. Identify the type of PDO:
   • Fixed supply PDO: Defines a fixed voltage lan saiki
   • 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 lan saiki.
2. Nemtokake paramèter:
   • Voltage: Voltage tingkat sing PDO menehi utawa njaluk
   • Current / power: The current (for fixed and variable PDOs) or power (for battery PDOs) the PDO provide
     or request.
3. Use the STM32 Cube MonUCPD GUI:
   • Langkah 1: Ensure you have the latest version of the STM32 Cube Mon UCPD application
   • Langkah 2: Connect your STM32G071-Disco board to your host machine and launch the STM32 Cube Monitor-UCPD application
   • Langkah 3: Select your board in the application
   • Langkah 4: Navigate to the “port configuration” page and click on the “sink capabilities” tab to see the
     current PDO list
   • Langkah 5: Modify an existing PDO or add a new PDO by following the prompts
   • Langkah 6: Click on the “send to target” icon to send the updated PDO list to your board
   • Langkah 7: Click on the “save all in target” icon to save the updated PDO list onto your board[*].

Iki mantanampbabagan carane sampeyan bisa nemtokake PDO pasokan tetep ing 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

Exampkonfigurasi le

Kanggo PDO sumber tetep karo 5 V lan 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[*] .

Mbangun PDO melu netepake voltage lan saiki (utawa daya) paramèter lan configuring wong nggunakake alat kaya STM32CubeMonUCPD utawa langsung ing kode. Kanthi tindakake langkah lan examples kasedhiya, sampeyan bisa èfèktif nggawe lan ngatur PDO kanggo aplikasi USB PD.

Is there a function for a prioritizing scheme with more than one PD-sink connected?

Ya, ana fungsi sing ndhukung rencana prioritizing nalika luwih saka siji PD-sink disambungake. Iki utamané migunani ing skenario ing ngendi sawetara piranti disambungake menyang sumber daya siji. Distribusi daya kudu dikelola adhedhasar prioritas.

Skema prioritas bisa dikelola nggunakake fungsi USBPD_DPM_SNK_EvaluateCapabilities. Fungsi iki ngira-ngira kapabilitas ditampa saka sumber PD lan nyiapake pesen request adhedhasar syarat sink lan prioritas. Nalika nangani macem-macem sinks, sampeyan bisa ngleksanakake rencana prioritizing dening nemtokake tingkat prioritas kanggo saben sink lan ngowahi fungsi USBPD_DPM_SNK_EvaluateCapabilities kanggo nimbang prioritas iki.

content_copy
uint32_t fixed_pdo = 0;
fixed_pdo |= (100 << 10); // 5V (100 * 50mV)
fixed_pdo |= (30 << 0); // 3A (30 * 10mA)
fixed_pdo |= (1 << 31); // Fixed supply type

/* Define a Fixed Supply PDO */
uint32_t fixed_pdo = 0;
fixed_pdo |= (voltage_in_50mv_units << 10); // Voltage in 50mV units
fixed_pdo |= (max_current_in_10ma_units << 0); // Max current in 10mA units
fixed_pdo |= (1 << 31); // Fixed supply type

Apa wajib nggunakake DMA karo LPUART kanggo GUI?

Ya, iku wajib kanggo komunikasi liwat solusi ST-LINK.

Apa setelan LPUART 7 bit kanggo dawa tembung bener?

Ya bener.

In the STM32CubeMX tool – there is a check box “save power of non-active UCPD – deactive dead battery pull-up.” What does mean this check box if it is enable?

Nalika SOURCE, USB Type-C® mbutuhake resistor pull-up disambungake menyang 3.3 V utawa 5.0 V. Iku tumindak minangka generator sumber saiki. Sumber saiki iki bisa dipateni nalika USB Type-C® PD ora digunakake kanggo nyuda konsumsi daya.

Is it necessary to use FreeRTOS for STM32G0 and USB PD applications? Any plans for non-FreeRTOS USB PD examples?

Ora prentah nggunakake FreeRTOS kanggo aplikasi USB Power Delivery (USB PD) ing mikrokontroler STM32G0. Sampeyan bisa ngleksanakake USB PD tanpa RTOS kanthi nangani acara lan mesin negara ing daur ulang utama utawa liwat interrupting rutin layanan. Nalika wis ana panjalukan kanggo USB Power Delivery examples tanpa RTOS. Saiki ora ana ex non-RTOSample kasedhiya. Nanging sawetara AzureRTOS example kasedhiya kanggo seri STM32U5 lan H5.

In the STM32CubeMX demo building a USB PD application for STM32G0, is HSI accuracy acceptable for USB PD applications? Or the use of external HSE crystal is mandatory?

HSI nyedhiyakake jam kernel kanggo periferal UCPD, mula ora ana gunane nggunakake HSE. Uga, STM32G0 ndhukung tanpa kristal kanggo USB 2.0 ing mode piranti, saengga HSE mung dibutuhake ing mode host USB 2.0.

Apa ana dokumentasi sing bisa dakrujuk kanggo nyetel CubeMX kaya sing wis diterangake mengko?

The documentation is available in the following Wiki link.

Is the STM 32 Cube Monitor capable of real-time monitoring? Is real-time monitoring possible by connecting STM32 and ST-LINK?

Ya, STM32CubeMonitor bisa nindakake pemantauan nyata kanthi nyambungake STM32 lan ST-LINK.

Apa VBUS voltage / fungsi pangukuran saiki tontonan ing layar monitor kasedhiya kanthi dhasar lan gawan ing Papan UCPD-aktif, utawa iku fitur saka Papan NUCLEO ditambahaké?

Akurat voltagpangukuran kasedhiya native amarga VBUS voltage is required by USB Type-C®.
Accurate current measurement can be done by TCPP02-M18 / TCPP03-M20 thanks to high side amplifier lan shunt resistor uga digunakake kanggo nindakake liwat pangayoman saiki.

generator kode aplikasi

Can CubeMX generate an Azure RTOS-based project with X-CUBE-TCPP by the same way with FreeRTOS™? Can it generate the code managing the USB PD without using FreeRTOS™? Does this software suite require an RTOS to operate?

STM32CubeMX generates code thanks to the X-CUBE-TCPP package using the RTOS available for the MCU, FreeRTOS™ (for STM32G0 as example), utawa AzureRTOS (kanggo STM32H5 minangka example).

Can X-CUBE-TCPP generate code for dual Type-C PD port such as STSW-2STPD01 board?

X-CUBE-TCPP can generate code for only a single port. To do it for two ports, two separated projects have to be generated without overlap on STM32 resources and with two I2C addresses for TCPP02-M18 and be merged.
Untunge, STSW-2STPD01 has a complete firmware package for the two ports. It is then not necessary to generate code.

Apa alat desain iki bisa digunakake karo kabeh mikrokontroler nganggo USB Type-C®?

Ya, X-CUBE-TCPP bisa digunakake karo STM32 sing ngemot UCPD kanggo kabeh kasus daya (SINK / SOURCE / Dual Role). Bisa digunakake karo STM32 kanggo 5 V Type-C SOURCE.
