Hello!I am using STM32-NUCLEO-F412ZG board. I want to use SDIO (only IO) functionality as host.I am able to init, read, write to SDIO peripheral using polling.Before asking question let me give some background of implementation,Not using DMA4 bit SDI...
I have a question regarding the VREF+ Pin in the above mentioned device. The datasheet DS5792 Rev 13 of the STM32F103xC devices states on page 36: " Unlike in the LQFP64 package, there is no PC3 in the WLCSP package. The VREF+ functionality is provid...
Hi there !Is the first time i wrote at this forum. I start to work with UART and DMA ,and i configurate the buffer in circular mode. I don't understa why when i call the library he continus to send over and over all i have in the buffer , i appearanc...
Hi every body. I want to manage two events with general purpose timers 16 and 3. As a convention in ARM processors, as much as I know, the lower interrupt number corresponds to the higher priority. So I think I need to manage event with higher priori...
Hi,In RM0433 Reference Manual there is a description of the AXIM indicating the possibility to change the QoS for the AXI switch matrix, but cannot find the reference for the indexes used in AXI_INIx_READ_QOS or AXI_INIx_WRITE_QOS.If there any manual...
I have a problem where my SPI clock produce 16bit, where I already set it to 8bit. I am not using any HAL driver, but I am learning from online course to develop my own driver from scratch.I have a problem at SPI master slave.The program is like this...
hello, i am developing my project in a stm32f103c8 (bluepill) with Keil and CubeMX, i want to use a nrf24l01 transmitter and for this i looked for a tutorial which is exactly what i want to do. the problem is that when i do it i notice that the radio...
I want to use DMA1_Stream5, Channel 4 to receive variable length packets on USART2. the first 3 bytes of each packet contain a protocol ID, a packet type and packet length. I initially set the RXNE interrupt enabled so I can interpret and decode thos...
Hi,I have a project in which I have to connect my PC to a measurement device thanks to VBA. I would like to use a mcu in order to control a component related to the device. This component is a decoder using the mcu outputs as input signals. These sig...
