Hello,I'm using the NUCLEO-F722ZE EVB.Page 155 of the datasheet describes the ADCs characteristics: https://www.st.com/resource/en/datasheet/stm32f722ze.pdfFrom the NUCLEO-F722ZE schematics I see that VDDA as well as VREF+ are 3.3V. VREF- is zero vol...
I'm trying to test the window watchdog timer but when I'm calling HAL_WWDG_Init(), it redirects to reset handler and whole system restarts. Below is my code, I'm showing here only important lines./******************************************/WWDG_Ha...
I'm trying to receive many 24 bits transfers over SPI with no interrupts. SCLK needs to be driven by the STM32. The throughput required would starve out the CPU if any interrupt was needed between/on transfers.From other forum posts, I've seen that t...
Hi,I have a design with a STM32F301 controller. I don't need JTAG, therefore I want to reuse the JTAG pins for other purposes.Is it a problem if the NJTRST signal is toggled when the uC is starting up? Could this affect the uC operation, or does this...
Hi,AN2606 (STM32 microcontroller system memory boot mode) states e.g. for the STM32F301, that in system memory boot mode both USART_TX pins (USART1_TX & USART2_TX) are used as outputs. Is the TX pins really configured as outputs as soon as the system...
Hello, I need to calculate checksum over a struct I have defined. Can anyone please help me with this? The data is structured as below: typedef struct eeprom_struct { // char serial_number[5]; float detector_comp_ch0; float detector_comp_ch1; fl...
I am trying to understand the priorities, subpriorities and priority grouping in my stm32f407-Discovery.I would like to have 3 external LEDS (LD_A, LD_B, LD_C) and 3 interrupts (IT_A, IT_B, IT_C) with. IT_A has a highest priority, IT_C has the lowest...
We use the STM32H743BI.We have a problem with writing the Backup-RAM if the mapped variables size is not multiple of 32 Bit.According to the reference manual (rev. 7) the backup RAM is accessible in 32-bit, 16-bit or 8-bit data mode. (RM0433 Rev 7, p...
Hello, i'm working with the STM32F746G-DISCO development kit. I need to use 3 SPI in reiceive only master mode (each SPI have the same clock). The data comming from the SPI are clocked at 4[MHz]. I need to use DMA to transfer data from the SPI periph...
