I am using the B-L072Z-LRWAN1 board. All global variables are their initialized values up until SystemClock_Config() executes HAL_RCC_OscConfig() which executes HAL_InitTick(). Once it reaches that point, all the global variables get filled with garb...
Hi,I'm working on POST using X-cube STL in stm32h745zit3 using IAR 9.30.1 version, while flashing the code into target STM32 board it showing error in Debug log post build command everything is fine, on build it's showing CRC area injected successful...
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...
