Hi all,I am using an ST32F091 micro and using RS-485 to communicate over the UART port. I have a 485 transceiver that handles the 485 scaling part. I am using an interrupt based Rx and Tx on the UART. I am encountering a very weird problem in that wh...
i want o create a .exe same like mentioned below,its taken from :AN3064I want to create a software to communicate STM32F446RE through UART1 to change the UART2 parameter setting & to see the certain variable value Declare in code.And then need to ex...
Hi everyone!i have a custom board with h743vit6 on it when i'm trying to access flash like this:cell_data = * (__I uint32_t *) address;i'm getting random hard faults from time to timeat first everything works fine, but after hard fault happens once, ...
Hi, I've been wanting to understand the reason for WRITE_READ_ADDR offset address used in example codes, below is the snippet, to give some idea what I am talking about.so why 0x0800 ? #define WRITE_READ_ADDR ((uint32_t)0x0800) for (uwIndex...
Hi all,I'm using a 480 MHz STM32H753 uC for a graphics project, and I'm trying to use a very fast PWM signal. I can achieve a 5 MHz square wave that is relatively clean, but when I up that to 10 MHz it's clear that the rise/fall times are too long, a...
I have a NUCLEO-L011K4 dev board, and unfortunately I can't get any of the sample programs to work. The board doesn't show up on the host machine. I'll walk you through the steps I tried on Windows, but I also on Mac and it didn't work there either:I...
Hi,I have to read a sequence of five ADC channels each 100us. In the past, I used the common way by DMA channel 1 and an interrupt at reading completion to get all values. Unfortunately I need most of the DMA for other purpose this time and I'm wonde...
Hello, I'm new to embedded software and I have 2 questions about UART communication.I've coded UART interrupt and have no problem with the transmit function, but the HAL_UART_Receive_IT(&huart2, rx, 10);only read the first byte I passed to the serial...
I've configured my STM32F303RE to send the COMP4 to the output (PB1) as well as to TIM4_Ch2. I also am running an external signal generator in from PB6 to TIM4_Ch1.I can see the COMP4 output on PB1 but not at the TIM4_Ch2. I can see the external sign...
I am trying to set up FMC to work with external RAM. The code compiles and works with KEIL, but I am trying to make it work with STM32CubeIDE. The code compiles and runs, but the RAM is not initialized. I copied all of the code, including the .ioc fi...
