Hello,I've been using STM32F051C8 on some of my projects and I recently realised that, my ADC is not converting accurately. I connected my Vdda to Vdd, that is 3,3VDC and tried conversation routine below.Here is the initialisation: Single Channel con...
I would like to dump all Cortex-M4 registers of my STM32F405 microcontroller over a UART. I have found the Technical Reference Manual (https://static.docs.arm.com/100166/0001/arm_cortexm4_processor_trm_100166_0001_00_en.pdf) but there are tons of reg...
I'm reading ADC1 and ADC2 in Dual Regular Simultaneous mode using DMA on a F334R8 nucleo board, as per instructions in UM1786 section 6.2.2 "Execution of ADC conversions":void readADCs(void) { // enable ADC slave if (HAL_ADC_Start(&hadc2) != HAL_...
I want use external memory IC(IDT 7204 FIFO memory)I use two STM32H743II(one is write FIFO, one is read FIFO)I think read was good work.but write is not good.I set FMC LCD Interface like Cubeset pictureI think one data write operation, NWE pulse appe...
I want write only some bytes but before that I have to erase a full sector.If I don´t want to loss data from that sector I will need save them.If sector size is 128Kb, how can I save all data? Thank you !
Hello, I am using the STM32F767ZI board and I want to measure the execution time of a function. The function I want to measure is a function I created. At the moment, I use the timer 9 configured in internal clock (216 MHz) with: Prescaler = 108 Coun...
Hii need to build a simple IOT motor control unit. I also need OTA update.what is the quickest way of getting started?Mongoose os? What else is there?Thx
Hello, it is the first time when i have to deal with microphones and PDM interface. I just can't get correct data from the microphone, or the data is correct but i am doing something terribly wrong. I configure I2S to sample microphone with DMA. Whe...
Hello all, I am still attempting to create my project on the STM32F411RE that is capable of taking in 3 sinusoidal signals and return the frequencies + amplitudes for these signals. Thus I need to use the CMSIS-DSP pack, but this is continuously givi...
I am developing with STM32F413.I try to download the program using USART1, but the FLSH LOADER DEMONSTRATOR recognizes it as another device. (STM8)What should I check?
