Hello everyone.I'm studying in STM32F4 and learn DMA module using Example code of St. The example show how to use DMA in Burst feature to do 3 transfers into timer register beginning at TIMx_ARR after DMA update request.But I don't understand why add...
Posted on July 15, 2018 at 09:26Hi,SBSFU gives me the warning 'SECURE ENGINE INITIALIZATION WITH FACTORY DEFAULT VALUES' on every new power-up of the microcontroller. Is this behavior normal after a power-cycle or is anything not configure correctly...
Hello,I am working on Power Reduction and we are using STM32F446RE Microcontroller. In the RM i found this, "the regulator output voltage (around1.2 V) can be scaled by software to different voltage values (scale 1, scale 2, and scale3 can be configu...
The dev kit documentation states that the module runs on the 860-930 MHz range that, according to the transceiver doc, should be the band 1.Does anyone know if it's possible to change the band to 2 or 3? Or there is any limitation for that?Thank you ...
Hello, I am using NUCLEO F49ZI. I am trying USART for Modbus Master. So after I send command to slave device, I would like UART to be listening mode or receiving mode. however, I confuse USART2_IRQHandler() and HAL_UART_Receive_IT(&huart2, pdata, 2...
Is it possible to send 9-bit SPI transactions on the STM32F413? I'm only seeing options for 8 or 16 bit. We are trying to interface with an LCD that only supports 9-bit SPI.
Hi All,I've been struggling with this for a while now. I have designed a new board based on the STM32L476 to replace an old design using a PIC. I cannot for the life of me get the I2C to work.I have used STMCubeMX to pinmux and configure / generate...
