Resolved! USART3_IRQHandler is not invoked.
char recv_string[10];char data;int count = -1,i,data_check = -1;void USART3_IRQHandler(void) //my interrupt handler{ if(USART_GetITStatus(USART3,USART_IT_TXE)) { data = USART_GetChar(); if(data == 0x0D || data == 0x08) data_check = 1; e...
UART interrupt lost
Under FREERTOS on UART3, I receive a 40 byte packet every 2.5ms @ 921600 baud . I programmed the Rx FIFO to interrupt at 1/2 level threshold. Everything works fine for about an hour. Then, for some reason, I get an overrun condition which seems to me...
Disabling DMA has no effect on DMA transfer compelete flag (TCIF)
Posted on April 05, 2018 at 17:03Hello,Following my question here https://community.st.com/0D50X00009XkWuQSAV , I'm able to receive data from the UART peripheral to the specified buffer.Now I'm trying to implement the same method described here http...
STM32F072C8 CANBUS Loopback working but Normal mode isnt.
Hi I am hoping someone can help me with a frustrating problem. I have two boards setup with STM32F072C8 parts. I have downloaded the examples from ST which are for a larger footprint part and modified the code to run on the 48 pin parts. The loopback...
execution time-STM32F429zi
i am just executing a for loop of 4096 time. But it takes more than 1 ms in stm32f429zi series. Clock frequency is 180MHz. How it can take that much time or whether it is executing some other function in back end.
Resolved! Application start address can be != start of flash ?
Hello,I need to use the example which boots (jumps) into application in external memory, but with a very slight modification:So that the start address of application can be somewhere inside the flash, not particulary at the start of flash, as it is n...
M7 microcontroller with eDRAM?
Is there any proposal to integrate EDRAM into cortex-M7 microcontrollers in the future?Thanks.
Core peripherals?
Where, in the documentation of STM32 devices, can I find out which optional core peripherals are implemented?
