Is it possible to change the Frequency Band in the B-L072Z-LRWAN1?
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 ...
UARTS
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 commands on the STM32F413
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.
STM32L476 I2C problem
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...
Mark and Space parity on UART?
Posted on November 07, 2013 at 00:26Does anyone know if you can set Mark or Space parity on the STM32 USARTS?I only found that you can set Even or Odd parity so far. I need to configure an STM32 for hardware that uses Mark and Space parity bits so a...
Problem with synchronization between STM32F7 Nucleo-F767ZI and OV5642 camera by Omnivision. How setting the external synchronization of the OV5642 and Nucleo-F767ZI?
I have an issue because the DCMI stay in a busy state and never acquire data from the DCMI. I have configured the camera for a VGA resolution and i want acquire that data through parallel interface using the DCMI and DMA of Nucleo board.Please, i hop...
