LORA DATASHEETThe default settings for the UART interface are 57600 bps, 8 bits, no parity, 1 Stop bit,no flow control. The baud rate can be changed by triggering the auto-baud detectionsequence of the module. To do this, the host system needs to tra...
Hello.I have been working on a project where the I2C based sensor I have chosen works by itself. When I enable a SPI based module, the I2C sensor does not seem to send any data.The I2C lines don't even have any conflicts with other pins.I have includ...
I order the X-NUCLEO-OUT02A1 and I work with a NUCLEO-F746ZG.These two boards aren't directly compatible I know.But they communicate with SPI, so I'm sure that you just can implement the communication with a bit of mapping with some breadboard wires....
STM32H7 SPI DMA not workingHi. I have stm32H745 nucleo board, in my project i want send data from MOSI via DMA (i did the same on old F4 discovery correctly).PE_14, SPI4 , DMA2_stream3, DMUX11=84 (for tx spi4)In project i need to send data (fb[][]) t...
I wanted to know which channel is converted latest. I configured as belowhadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc...
Hi Everyone. I have encountered a problem in using LIS3DH SPI with STM32F0x MCU. I used to configure and set LIS3DH accelerometer with ATXMEGA families without any issues but this time I really can not understand the origin of my fault. I'm using bar...
the same config in USART1 and USART2 is normal,but in USART3 is doesn't work
I'm trying to get square pulses on PB8 with TIM16.1 output compare, but no pulses on pin (timer seems working: CNT counting, SR flags changing).Setup code:gpio_mode(GPIOB,8, GPIO_MO_AF); gpio_af(GPIOB,8, 2); // PB8 as AF2 rcc_apb2_on(RCC_APB2_TIM16);...
Hi, I am trying to write an interrupt code to trigger LED(PB14) using user button on my NUCLEO board(PC13). however, as I observed from the debugger, pending bit for line 13 constantly at 1 without pushing the button at all.The EXTI->PR1 = 1<<13 stil...
I use 6 ADCs.I use 3 channels(Ch1, Ch3, Ch13) for ADC1.I use 3 channels(Ch2, Ch4, Ch15) for ADC2.Use DMA1 Channel1, DMA1 Channel2 respectively.DMA1 Channel1 is used by ADC1,Number Of Conversion is 3, Rank 1 = Ch1, Rank 2 = Ch3, Rank3 = Ch13.When usi...
