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...
If I use the example BLE_Sensor_Demo + OTA_Reset_Manager I can update the firmware without any problem. I have followed the indications given in The BlueNRG-LP (over-the-air) firmware upgrade document (AN5463) and I don’t see any difference between m...
