Hi, I am a newbie with STM32. I need help.I want to configure that PA15 pin (which by default is used as JTDI), as a GPIO output.I've added the following two lines to the beginning of the generated code of MX_GPIO_Init():LL_GPIO_SetAFPin_8_15(GPIOA,L...
Hello. I have a cap touch with an ili2511 touch controller board on it. I need to drive it with stm32 IIC but I can not find anything to help me. I need help with writing or finding its driver. please help me I am so confused. I would appreciate your...
I'm using an STM32L4A6 on a custom-designed board. I'm using STM32CubeIDE 1.16.0 and CubeMX to generate my project. I'm running into an issue where intermittently (let's say every few days, but it seems random), my board will not bootup for a numbe...
SPI communication by DMA and SPI communication by BDMAWe would like to confirm the difference between SPI communication by DMA and SPI communication by BDMA.for some reason, the MISO data output (slave output) is delayed by 2 to 3 CLK in SPI communic...
Hi all,I have the CPU STM32F103 on board. I am using STM32CubeIDE for SW development and STM32CubeProgrammer for burning.On some point during development, I couldn't burn the CPU anymore - I get various types of error messages, like 'Can't erase the ...
HelloI am using STM32F103C8T6 microcontroller in my project and internal RTC is used with external 32.768Khz oscillator and CR2032 battery is connected to VBAT pin for RTC backup. RTC is working fine.In my application I am running timer which increme...
Posted on May 24, 2018 at 13:11Hi,I'm using the NUCLEO-H743ZI board with the STM32H743 MCU.I'm using the HAL SPI1 module to transmit a buffer of 4 words (16 bits) and receive the corresponding 4 words into another buffer.The component the MCU is com...
Hi;I have a tlv493d magnetic encoder, with which I would like to communicate via i2c with an stm32f4 MCU. I can successfully initiate communication with this sensor via I2c, to perform an initial configuration of the sensor. I can verify this by way ...
Hello STM32 Community,I am using the STM32F407G-DISC1 development board and have successfully implemented an RTC alarm that triggers every minute. The RTC is configured to use the LSI (Low-Speed Internal) clock signal.My goal is to have the microcont...
We are developing software that uses GPIO interrupts.We would like to test if the GPIO interrupt handler is working properly, but is it possible to set the pin assigned to the GPIO interrupt High/Low in software?Is this only possible by inputting a s...
