Wondering if the STM32l4 RTC could be used to wake the processor from standby mode after 1 month.Powered by the LSI, would the time drift beyond usability? Ie. It does not matter if the device wakes up 30 days or 31 days later. Just as long as its in...
Hello everyone In Keil Projects we are able to change Stack_Size and Heap_Size in "startup_stm32f746xx.s" file like this :Stack_Size EQU 0x400Heap_Size EQU 0x200BUT in IAR projects there isn't such code line in the startup file related...
Hello, We have an application where we want to use basic serial ports to communicate between two STM32 processors (32F030RCTs). The two processors are on two different boards but with the same ground system. Each processor receives and transmits per...
I'm facing a weird situation. I'm using SPI simplex receive-only mode on a Slave STM32H743. It has been working fine for a while. Until now I was enabling only the RXP interruption. The SPI1 interrupt was triggered as expected.Now I enabled also EOTI...
Hello,according to the datasheet of STM32L072CB there is a margin of controllers which have at 26kHz@Xx°C or 56kHz@Xx°C (first row of table)?So in total there is a production margin (26kHz to 56kHz) and additionally a temperature drift during run tim...
I am trying to use the STM32H743I-EVAL FDCAN_Com_IT example code to run CAN on STM32H743ZIT6. I am trying to transmit at regular intervals. When I look the signals on a scope, the TXD goes low for just a bit interval and then remains high. Here is m...
Hi,I have a custom project with the internal FDCAN controllers and I try to set the bit timings to 1 MBit/s for arbitration and 2 MBit/s for data phase. For the project I use thel NUCLEO STM32H745ZI-Q board with a selfmade expansion with containing t...
Hello,I am using STM32CUBEIDE and STM32H743 microcontroller. I want to allocate an array in D2 domain SRAM I tried the following approach:1) In the linker script (STM32H743_RAM.ld) i created a separate section called dmabufferas follows.dma_buffer...
