CAN_ESR_LEC =0x05.which means bit dominant error, CAN_MCR_DBF bit is at 1.how to trouble shoot it
Hello, teachers. I'm an introductory to stm32.I am posting like this because there is a situation where communication is not possible while communicating i2c between stm32.This is the current structure.STM32F103VE Use 1 Master, STM32F302CB Use 5 Slav...
I am using STM32F072RB Nucleo board and in the technical reference manual it is mentioned that "Please refer to the “Alternate function mapping�? table in the device datasheet for the detailed mapping of the alternate function I/O pins.". But I am no...
Device Used : STM32F030C8, 48pin LQFP48I am driving MOC3043 Opto-Isolated Triac Driver so I need atleast 5 mA current sourced from the GPIO outputGPIO used with the MOC3043 is PA15 max current observed is 4.86mAOnly a single GPIO is configured at a t...
Hi, Iam using DMA technique to digitise a sine wave using nucleo-H743ZI2, where Adc clock frequency is 36.5MHZ . Iam taking single data at a time and sending out using usart with a baud rate of 250000, the issue I am facing is when I increase th...
Hello!i am working with the stm32h745 nucleo 144 board.i want to be able to debug both cores simultaneously using the onboard STLINK debugger, with no luck so far.followed the instructions from this ST document: https://www.st.com/resource/en/applica...
I've spent a fair amount of time getting small bits of code working so I can build them up into a larger working application. The code below works but I'm struggling with a way to move the parts related to GPS and the UART into separate files or clas...
Board : STM32F746GHow to use CCMRAM?What is the use CCMRAM?What is the Size of CCMRAM?Thanks Manikandan D
Please tell me how to transfer data so that the CPU can calculate the converted values of ADC1,2,3 with STM32H725 at the fastest speed.I recognize that there are ways to use DMA and MDMA and ways to use D-cache. Thank you.
I don't know so please let me know.I would like to use Cortex-M7 branch prediction. Is it necessary to set registers in particular?
