Interrupts Management
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...
Resolved! Problem with STM32H743 backup ram access with 16 Bit
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...
SPI Communication with DMA transfer
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...
In STM System WorkBench I Want to load Specified .bin File with the symbols from Specified .elf file
As shown the image below I do not want to load .bin file extracted from the .elf file . I want to specify other .bin file can we do this and how to load different .bin file and .elf file
Reading flash and sending to UART
Hello,I'm currently struggling to setup flash reading launched from a PC.I've used the example code for simple write and read with HAL from STM32 Cube SW.The example show a reading of an uint32_t after writing a uint64_t.Here is my code:Writing flash...
STM32F7508 Board crash when using SPI recieved variable in a simple math formula.
When I receive the SPI variable I save this as an int like this:uint8_t spiRxBuf;uint32_t highByte;uint32_t lowByte;HAL_SPI_Receive(&hspi2, &spiRxBuf, 1, 10); highByte = spiRxBuf; HAL_SPI_Receive(&hspi2, &spiRxBuf, 1, 10); lowByte = spiRxBuf;int resu...
Triggering ADC1 from TIM2 CH2 on stm32F767
Hi guys, I've searched the forum and found a handful of posts with a similar issue but the search doesn't seem to be very good for seeing previous posts... Anyway, I've got a PWM output from TIM2 CH1 (200us perioud, 25% D.C.) and I have another PWM f...
LPTIM1 vs TIM6 - low power
According to STM32L052K8 datasheet in table 39 page 72 of this document:https://www.st.com/resource/en/datasheet/stm32l052k8.pdfThose timers consume uA/MHz:Peripheral | Range 1 | Range 2 | Range 3 | Low-power sleep and runLPTIM1: 10, 8.5, 6.5, 8TIM6:...
Pin Function Document
Hello,I'm using the NUCLEO-F722ZE EVB.In page 43 of the following document there seems to be a pinout list which specifies the signal name of each pin :https://www.st.com/resource/en/user_manual/dm00244518-stm32-nucleo144-boards-stmicroelectronics.pd...
