Dear readerI hope someone can help me with my question. I have programmed an ADC1 on a STM32F103 with the following functions activated:Continues conversion modeScan mode with two channels A0 And A1 DMA to an array in memory ADC_data[2]( ADC Interrup...
Hi guys, I have a crazy curiosity at my hands. The STM32G474 is a "category 3" device, therefore it has 128kB of RAM with the upper 32kB being CCM-SRAM. It is really nice that it is all addressable in one continuous block.When i use the upper 16kB of...
Hello,I'm working with the NUCLEO-F722ZE EVB on STM32CubeIDE.I'm Looking for a C example that explains how to use the device's DAC (Digital to Analog Converter)
When i use iar embeded workbench its work correctly with out f11 .While it works by itself , its pins are resetting.I want to learn what happening here .Even power is enough.Model : stm32f429COD:CONTROLREAD LDR R0, =USART2_DR LDR R1, [R...
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...
Hi all,I am using STM32F042 series mcu, and IAR as compiler.I have some #define statements in main.h which provides some setting configurations. Forexample we have different custom pcbs which have either active low or active high button. If I place #...
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...
