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...
Hi,Recently I bought a STM32H755ZI Development Board and would like to use it for UART RX with DMA. I used CubeMX to generate the project and everything worked fine with the function "UART_RECEIVE_IT()" but never worked with UART_RECEIVE_DMA(). I've ...
I had gone through the datasheet and user manual. I could not fined respective CAN_TX, CAN_RX pins on the board(Pin Number PA12(CAN_TX), PA11(CAN_RX)). These pins are not available on the Discovery board. Then how can I take CAN TX, RX data to the ex...
we are configured that pin as Input. We got 0.5V drop at PA7 pin after flashing code.Please let me know the resistor values for all GPIO pins
Hi,First of all, I apologize for my English level, I am not a native speaker. I hope you can understand me Explanation:1) PHYSICAL WORL: I have searched for information on the electronics behind the memories. In 32 bits microcontrollers, the memory...
Hi,I am using STM32H7 Nucleo board. I soldered an external 25MHz crystal oscillator with 22 pf capacitors(Load capacitance of crystal =20pf) but the controller doesn't seem to work on 25Mhz crystal oscillator. I tested this by blinking an LED at 1 se...
I am having a little difficulty getting a USART 2 signal to output to a logic analyser using transmit Tx serial asynchronous communication. I have configured a USART 2 peripheral to communicate through a DMA. The GPIO pin PA2 is outputting a constant...
Dear Sir, Debug and driver folders are not created in code generationDebug option is also not highlighted in menu button.Below is the screenshot of that please help.
Hello,I have a problem with EXTI0 after a compilation with 03 or Os.In an ISR (EXTI0 for exemple) the place where the __HAL_GPIO_EXTI_CLEAR_IT is made seems to influence its action. If it is immediately followed by an exit from the ISR it does not wo...
I've written an External Flash Loader and successfully tested erase, read, and write functionality first in my own firmware, then with ST-Link Utility v4.5.0, and also with STMCubeProgrammer v2.6.0.However, when I try to use it to debug with TrueStud...
Hello Everyone!I have thoroughly understood touch sense controller peripheral of STM32F051C8T6, I have also developed a test code using the HAL layer and is working file and detecting touch (i.e. is count value decreasing when finger comes near elect...
