Hello, I am brand new to all of this flashing firmware and stuff, I'm trying to find a way to get the firmware from a shark AV751 I just took apart with an STM32F071 to possibly make a custom app and add mapping? I know I am jumping from step 1 to st...
Zoomed-in view of MISO:Expected output: 0x0 0x0 0x0 0x58We see the 0x58 being received on MOSI, but still not aligned with the clock. Probably, it is not being sampled correctly by STM32.And importantly, the CS is not triggered before generating cloc...
Hi,I'm using STM32G431RB on the NUCLEO-G431RB developement board.I want to generate a signal from an array each time an external trigger is received.The signal is sampled with the TIMER6 trigger, which is rised every 1us. (MCU clock is 170MHz, TIMER6...
Posted on August 08, 2016 at 19:20Hi all,Is the VUSB input required/recommended for self-powered STM32 USB device?From everything ive read, the VUSB input is required for connection/disconnect detection, but in practice, everything seems to work jus...
Hi,I am trying to use 3 ADCs on STM32F407 with 'Triple regular simultaneous model only'. This option is avaliable in CubeMX configuration, but I can not get it working in the code. I would like to sample 3 channels using the 3 ADCs at the same time. ...
When finish run my code ，those code of enable like __HAL_RCC_GPIOJ_CLK_ENABLE();__HAL_RCC_UART8_CLK_ENABLE();__HAL_RCC_I2C4_CLK_ENABLE();do not change color of purple like the picture still black, this mean i lost some file o no、
Hi,I am working on STM32G474CET mcu. I am trying to use VREFBUFF voltage for ADC channel referance voltage. My configuration looks like the following. When i run the code, it stuck in the HAL_SYSCFG_EnableVREFBUF function. Whenever i check the 'ticks...
