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 !
Hi everyone.So my previous post just did not load for some reason.The problem is that for some reason I get this issue when I debug once I enable the interrupts.I am simply trying to respond on the TIM5 interrupt but I get thrown to a part of the fil...
I am not sure why but the moment I enable this interrupt the debugger goes to this file and just sits there. What is interesting is the stack trace changes if there are certain functions involved but the error never changes. So I removed all the func...
Hi everyoneI have an STM32F401RE board and I have an LED from pin PB6 to GND.In the same project that this snippet code below comes from I have a PWM running on PA5 pin and it is blinking.I have been at this all night and I can't figure out why PB6 i...
