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...
Due to the global chip shortages, we need to purchase a pin-compatible (LQFP100) version of the STM32F765VIT6. Since we don't need the 2k Flash we are looking at the STM32F7767VGT6, or the STM32F746VGT6. Both appear to have the same essential archite...
my code is jumping into hardfault handler during/after flash write procedure.some problem with mutex or task handling, can somebody explains how to hold the thread until the flash write is complete.note: flash write functions are called inside the "b...
