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...
hi i have simple code for send some data from one master 767 to other slavein master data will send in 2khz rate and 80 byte length but data in slave not completely correct on Rx buffer one data ok and next not, until end of buffer that repeated (for...
Hello everyone, I write here to know if someone can help me,how to be sure the systick value is good ? be sure that 5 seconds are well done ?thanks to help me !
