Hello.I am finishing a project where I measure voltage with an ADC using the STM32L431 and, for greater accuracy, I am using the OPAMP (PA0 = ADC1_IN0_VINP and PA3 = ADC1_IN_VOUT). For the STM32L431 on the STM32CubeMX, when activating the OPAMP in "F...
Hello Experts,I'm using the STM32L476 in one of my projects, with the main system powered at 3.3V (VDD), and a 1.55V coin cell (Murata SR621SW) connected to VBAT for RTC backup.The tamper pin (PC13) is connected to a normally closed (NC) anti-tamper ...
Hello Using a STM32U5G9NJHxQ.Using a 646x480 1byte per pixel monochrome Dcmi camera --> 310080 bytes --> 77520 words (32 bits) --> according to AN5020 6.4.8 this means Double buffer mode for medium resolutions, continuous capture in my case.Based on ...
Hello World;My Setup:Nucleo F767ZI BoardBOOT0 pulled highSCL/SDA on PB6/PB9 connected to Raspberry Pi I2C-1 and Saleae Logic Pro 8Nucleo board powered via USB from Raspberry PiGoal: Using ROM Bootloader over I2C for firmware updates (later on custom ...
I'm trying to find the best approach to accomplish the following: Read audio samples from a digital microphone using the ADF1 peripheral and use the LPDMA controller to store those samples in a SRAM4 buffer. An interrupt or event should occur when th...
Hi,we are using ADC with DMA for internal ADC channel like internal Temperature sensor, VBAT, VREF but we are facing issue related to accuracy please help me on this Configuration:ADC channel: adc_channel_config_t ADC3_temp_config = { .chann...
Hey everyone,I'm working on a custom board based on the STM32H753 MCU. I successfully programmed it using STM32CubeIDE initially, but ran into an issue when trying to re-flash it — I got the error:"Unable to erase flash memory to reprogram it"To work...
Hello,I’m working on a custom board based on the STM32H753IITx and I'm trying to access a microSD card via USB_OTG_HS using the USB Mass Storage Class (MSC). I've read this post, which is close to my use case, but unfortunately, I haven’t been able t...
Can any one please assist me.I have all 8 ADC down to GRND 0V I am using this command:HAL_ADC_Start_DMA(&hadc1, AD_RES_BUFFER, 8); The arry is:volatile uint32_t AD_RES_BUFFER[19] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; All 8 AD...
Hi,I am trying to establish a successful transfer using SPI in master full duplex DMA mode using a NUCLEO-H7S3L8 board (STM32H7RSxx family).For this purpose I wrote the following functions:#define U2A_CDC_U2A_ITF_TX_DMA_CH LL_DMA_CHANNEL_2 #define U2...
