Konfiguratsiya va dastur kodi

Qanday qilib PDO qurishim mumkin?

USB Power Delivery (PD) kontekstida quvvat ma'lumotlari ob'ektini (PDO) yaratish USB PD manbai yoki lavaboning quvvat imkoniyatlarini aniqlashni o'z ichiga oladi. PDO ni yaratish va sozlash uchun quyidagi qadamlar mavjud:

1. Identify the type of PDO:
   • Fixed supply PDO: Defines a fixed voltage va joriy
   • 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 va joriy.
2. Parametrlarni aniqlang:
   • jildtage: JildtagPDO taqdim etgan yoki so'ragan e darajasi
   • 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:
   • 1-qadam: Ensure you have the latest version of the STM32 Cube Mon UCPD application
   • 2-qadam: Connect your STM32G071-Disco board to your host machine and launch the STM32 Cube Monitor-UCPD application
   • 3-qadam: Select your board in the application
   • 4-qadam: Navigate to the “port configuration” page and click on the “sink capabilities” tab to see the
     current PDO list
   • 5-qadam: Modify an existing PDO or add a new PDO by following the prompts
   • 6-qadam: Click on the “send to target” icon to send the updated PDO list to your board
   • 7-qadam: Click on the “save all in target” icon to save the updated PDO list onto your board[*].

Mana sobiqampRuxsat etilgan ta'minot PDO ni kodda qanday belgilashingiz mumkinligi haqida:

/* 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

Exampkonfiguratsiya

5 V va 3A kuchlanishli statsionar PDO uchun:

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

Qo'shimcha fikrlar: 

• 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[*] .

Qadamlarni bajarish orqali va sobiqampAgar siz USB PD ilovalaringiz uchun PDO'larni samarali yaratishingiz va boshqarishingiz mumkin.

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

Ha, bir nechta PD-sink ulanganda ustuvorlik sxemasini qo'llab-quvvatlaydigan funksiya mavjud. Bu, ayniqsa, bir nechta qurilmalar bitta quvvat manbaiga ulangan stsenariylarda foydalidir. Quvvat taqsimoti ustuvorlik asosida boshqarilishi kerak.

Prioritetlashtirish sxemasini USBPD_DPM_SNK_EvaluateCapabilities funksiyasi yordamida boshqarish mumkin. Ushbu funktsiya PD manbasidan olingan imkoniyatlarni baholaydi va lavabo talablari va ustuvorliklari asosida so'rov xabarini tayyorlaydi. Bir nechta lavabolar bilan ishlaganda, har bir lavaboga ustuvor darajalarni belgilash va ushbu ustuvorliklarni hisobga olish uchun USBPD_DPM_SNK_EvaluateCapabilities funksiyasini o'zgartirish orqali ustuvorlik sxemasini amalga oshirishingiz mumkin.

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

Ha, bu to'g'ri.

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?

SOURCE, USB Type-C® ga 3.3 V yoki 5.0 V ga ulangan tortuvchi rezistor kerak bo'lganda. U oqim manbai generatori sifatida ishlaydi. Quvvat sarfini kamaytirish uchun USB Type-C® PD ishlatilmasa, ushbu oqim manbai o'chirilishi mumkin.

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

STM32G0 mikrokontrollerida USB Power Delivery (USB PD) ilovalari uchun FreeRTOS dan foydalanish majburiy emas. Siz USB PD-ni RTOSsiz amalga oshirishingiz mumkin, bu esa voqealar va holat mashinalarini asosiy tsiklda boshqarish yoki xizmat ko'rsatish tartiblarini to'xtatish orqali amalga oshirishingiz mumkin. USB Power Delivery uchun so'rovlar bo'lgan bo'lsa-da, exampRTOSsiz. Hozirda RTOS bo'lmagan example mavjud. Ammo ba'zi AzureRTOS sobiqample STM32U5 va H5 seriyalari uchun mavjud.

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 UCPD periferik qurilmasi uchun yadro soatini ta'minlaydi, shuning uchun HSE dan foydalanishning foydasi yo'q. Bundan tashqari, STM32G0 qurilma rejimida USB 2.0 uchun kristallsiz qo'llab-quvvatlaydi, shuning uchun HSE faqat USB 2.0 xost rejimida talab qilinadi.

Keyinchalik tushuntirganingizdek, CubeMX ni o'rnatish uchun murojaat qilishim mumkin bo'lgan hujjatlar bormi?

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?

Ha, STM32CubeMonitor STM32 va ST-LINK ni ulash orqali real monitoringni amalga oshirishi mumkin.

VBUS jildmi?tagMonitor ekranida ko'rsatilgan e/joriy o'lchash funksiyasi UCPD-ni yoqadigan platalarda asosiy va sukut bo'yicha mavjud yoki bu qo'shilgan NUCLEO platasining xususiyatimi?

Aniq jildtage o'lchov mahalliy sifatida mavjud, chunki VBUS voltage is required by USB Type-C®.
Accurate current measurement can be done by TCPP02-M18 / TCPP03-M20 thanks to high side ampko'taruvchi va shunt qarshiligi, shuningdek, haddan tashqari oqimdan himoya qilish uchun ishlatiladi.

Ilova kod ishlab chiqaruvchi

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) yoki AzureRTOS (masalan, STM32H5 uchunample).

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.
Yaxshiyamki, STSW-2STPD01 has a complete firmware package for the two ports. It is then not necessary to generate code.

Ushbu dizayn vositasi USB Type-C® bilan barcha mikrokontrollerlar bilan ishlaydimi?

Ha, X-CUBE-TCPP barcha quvvat holatlari (SINK / SOURCE / Dual Role) uchun UCPD o'rnatilgan har qanday STM32 bilan ishlaydi. U 32 V Type-C SOURCE uchun har qanday STM5 bilan ishlaydi.
