We are trying to develop a USB hub that supports AOA (Android Open Accessory).The approximate structure is shown below.Android Tablet ---- STM32 MCU ---- USB HUB IC ---- USB Devices(4EA)The reason for this development is to let USB communication and ...
On page 109/230 of the STM32F722xx datasheet (I use the STM32F723VE) it says that the capacitance of the external capacitor that is stabilizing the internal main voltage regulator should be 2.2 µF. We use 0603 capacitors (metric; so 0201 imperial) wh...
UM2552 has a paragraph 4.2.2: Send request messageA SINK must send a request message to ask for a new power level, the rest of the sequence is identical to AMS power negotiation. How and what should I do to start the process of renegotiation? How to ...
STM32H753HAL 1.19.1I need to reset the USB host dedicated pins (PB14/PB15) to their original state when stoping the USB HOST driver.The USB Host driver is activated on demand using MX_USB_HOST_init.The HS part is activated and the driver is well perf...
hello,I try to write a bootloader function fo the STM32g03 MCUthis is the code:void JumpToBootLoader(void){ UART_HandleTypeDef huart2;// System boot function pointer:void (*StartBootLoader)(void);// System address for the F76xxx family (see ST AN2606...
Hi, I'm designing a board in which the communication between STM32 and the host is UART over LVDS. So RS232 transceiver is not used in the design. And we want to upgrade STM32 firmware remotely through the UART LVDS interface by the host. But accordi...
The data sheet makes brief references to ethernet precision time protocol and a time stamp comparator using timer TIM2.PTP is not implemented in my project (unless it is deep down in the code; I didn't write it, but googling suggests the 32F4 is way ...
I need the X-CUBE-STL library and I want to import these needed files into my project which I programmed with STM32CubeMX. Is there any good tutorial how to use this library and which parameters needs to be adjusted?
Hello, I have tried this (How to create a Thread using AzureRTOS and STM32CubeIDE?) example with a Nucleo-F446RE board. Of course I have chosen the AZRTOS-F4 instead of the AZRTOS-H7 in the example. So line HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin);...
STM32F746 Disco. CubeIDE 1.8.0. Win 10. CMSIS-only (no HAL, no LL, full registers)Learning stuff. The purpose is to make a simple demo-program to make sure I understand how things work. Timers have been the most confusing piece so far due to amount o...
