STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
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...
I have downloaded the trace example from segger website https://wiki.segger.com/STM32H7#Tracing_on_ST_STM32H7B3. However, it doesn't work out of box due to the board does not have trace pins connected to the debug header by default. Have anyone tried...
I am told by that configuring a timer as master and others as slaves can generate multiphase pwm . but I cant figure out how exactly to set the configuration. I am aware its possible in few of the advanced MCU with HRTIM. But I want to use stm32f103 ...
