HiThere's a not-too-well worded paragraph from AN2606 on page 33:For STM32 devices embedding bootloader using the DFU/CAN interface in which theexternal clock source (HSE) is required for DFU/CAN operations, the detection of the HSEvalue is done dyna...
Hi. We use the STM32F3 series for a number of products. We were hoping to implement oversampling for the two ADC's based upon the Application Note AN5537, which indicated in Table 1 that the STM32F3 series has the oversampling engine on chip. Howe...
Hello, I am facing the below scenario in my development board. I am trying to do OTA update in my RIverDI 5 inch display module. I receive the firmware chunk from the ESP board which is connected through the external connectors of the riverDI module ...
I'm trying to store a simple runtime setting in flash memory of a stm32f103 with 64kb of flash.In my testing I'm targeting the second to last page at 63 with address 0x0800FFE0I can write fine to empty pages using HAL_FLASH_Program() but any call to ...
Hi all.Are there any guides on building the charge-through VPD device with the ST product? An illustration from the standard: The goal is to maintain the smartphone's supply from the external PD charger while maintaining the connection with a USB 2.0...
I'm using the ST Cube environment (IDE + MX) to configure the SPI2 peripheral in Full-Duplex Master mode on a STM32F105VBHX chip.It seems like the peripheral is not driving the NSS (chip select) pin (PB12). When the pin is selected for SPI2_NSS and ...
The code I wrote for the B-L072Z-LRWAN1 is supposed to count pulses on a falling-edge external interrupt pin. The pulse source is an Arduino which toggles its GPIO on and off every 5ms, for a 10ms pulse period. after 6 seconds, the B-L072Z-LRWAN1 tra...
I have a program with various tasks, in one of these I send a request and, after that, I wait for a response, so I have a cycle like this SendRequest(); do { WaitResponse(); DelayMillisecondS(200); }while (Timerisnotexpired()); the Problem is that th...
Hi,I am thinking using the STM32U5G9VJT6Q and configure the USB to USB-OTG but never used USB OTG before.The PCB would have its own power supply and only work when power is applied through it and never take power from the USB connector. The USB would...
Hello! I followed this video for CAN-bus https://www.youtube.com/watch?v=JfWlIY0zAIc&t=918s but as simply as it looks, my configuration doesnt seem to work, I'm working on the NUCLEO-F767zi, I started a new project with default config simply adding C...
