I am using STM32L476, running on MSI @ 16MHz, with MR Range 1 and 3.3V supply voltage. The problems described below are happening at room temperature. The processor is running Bare Metal. The ADC1 and ADC2 are configured in Regular Simultaneous Mode ...
Hi, I'm using Nucleo-L432KC board and I've got quite a few devices plugged in to it already. And I need to add another device using UART, but I'm using UART2 for debug output already and I2C1 (which always shares pins with UART1) for a couple i2C dev...
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, ...
