I want to make metal detector circuit using STM32 for material shorting specification of circuit is given below.It can detect ferrous and non ferrous both metal.digital out put hi when metal object detected.It can show detected piece area.It is capab...
Hi everyone!I have found that the System Memory (Boot ROM) is always mapped to 0x0000_0000 on the STM32L471RET6 that I'm developing on. The Flash Memory is mapped to 0x0800_0000 as expected but as soon as interrupts are triggered they jump to 0x1FFFF...
HiI want to test the execution speed of SIMD instruction. My demo as below.16-bit addition, for example.I find the instruction __SADD16() in cmsis_gcc.h. The execution time using __SADD16 is 27us and the time without __SADD16 is 23us. It seems like ...
Hi, i'm working with RTC and having issue about getting time. I'm calling HAL_RTC_GetTime function with HAL_RTC_GetDate, it's return old value of time. For example time is 00:10:00 and i called gettime function, it's return 00:09:38. I'm getting time...
I am new in st's mcu.I am going to switch my project to STM32L010 (Nucleo-L010RB).In my project, i need to let mcu going to stop mode and wake up it self every 100ms.How do i do it?Is there any code for me to study?
Hello Guys, I want to read multiple channels from my adc using DMA.However I want to implement it the following way:while(1){1. Start ADC DMA (scan, discontinous conv.)2. Wait for the completion (the CPU should just wait until the conversion of the m...
Hello I am very new to c programming and embedded design. I know there is a right way to do what I am trying to accomplish. I seem to be doing it the wrong way even though my code still "works" I am getting warnings on a couple lines of code. Line ...
Hi all,I got a strange issue. I'd like to use USART3 or UART5 on my STM32F446 chip. We have the chip on a pcb, so I am not talking about the nucleo board. The issue is when I do the system_clock_config(), the listed uarts does not work. void init() ...
I have the strangest problem ever seen and I would not believe it has it not been this repeatable: I have a single DMA controller running 3x streams. Two are for ADC and one for DAC. All three can run simultaneously, the DAC at 1 Msps and the ADCs bo...
I'm running a STM32L073 to generate a sine wave tone via I2S in normal DMA mode. The amplifier is a MAX98357A. The MODE pin is connected to VDD so only left channel is considered. I2S runs at 48kHz and the uC clock source is internal. The output tone...
