Hi everyone:cherry_blossom:I start in learning LIN bus and I wrote a basic example contain master task and slave task in STM32f103 and communicate with one slave (stm32f429), the problem in stm32f1 MCU in that the DMA read just once! so the first fra...
I'm having trouble understanding this from the datasheet and reference.What peripherals are allowable targets for DMA1 memory-to-peripheral transfers?Thanks, Best Regards, DavePS: I tried to use a stream in DMA1 to write to a DMA control register, an...
Hi Team,Am working with STM32L4R9 Discovery board,In this SOC, PMOD interface is configured to UART in defaultWhen am trying to use this a SPI interface, am facing issueCan you pls share me the sample pin configuration for PMOD connection to configur...
Hello.I try timer 2 on STM32F427 and I have a problem. It ticks too quick.Here is my system clock. I have external crystal: 25MHzClock I want to: 168MHzvoid SystemClock_Config(void) { uint32_t i; LL_FLASH_SetLatency(LL_FLASH_LATENCY_5); if...
Many of the "older MCUs" like STM32F4xx had an FSMC. I've been thinking about switching to the newer STM32F7xx and have bought a Discovery board for STM32F7508, but there are no references to FSMC in the documentation. Apparently F765/7/8/9 have a "F...
I'm working with the STM32F446 microcontroller and I'm using UART with DMA. The size of my UART packets is contained in the 3rd and the 4th packet bytes and I would like to use FIFO on the receive stream to increase the likelihood for successfully re...
Hi,I'm using the STM32F411RE device to decode MP3 audio files, i'm sending the decoded data to a MAX98357A amplifier via I2S and DMA, when the SCK signal is removed from the amplifier there's a DC offset at it's output which is causing a distorted au...
Hello community, I have a little doubt. Are all the GND pins internally connected inside the microcontroller? Is the analog reference (AVSS) internally connected with the digital one (VSS)? If it not, how is the isolation between them?I don't know wh...
Per STM32F405/7 and per datasheet DocID022152 Rev 8 (stm32f4xx) ... are the values referred to in datasheet as "Temperature sensor calibration values", at addresses 0x1FFF 7A2C & 0x1FFF 7A2E (see section 5.3.22), actual factory-calibration results th...
I changed linker to use all of these three memories in domain D2. Problem is next :When i put for example uint32_t tempArray[4] = {0x2B7E1516 ,0x28AED2A6 ,0xABF71588 ,0x09CF4F3C} __attribute__((section(".sram1")));this line in my code, when MCU is in...
