UART DMA RECEIVE ON STM32H755ZI DUAL-CORE MCU
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 ...
Resolved! I have pruchased a STM32L476VG Discovery board recently. I wanted to build a USB to CAN Interface. For that purpose I need to take CAN Tx, Rx data lines from the STM32 Discovery board and I have to connect those lines to any external transceiver.
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...
Resolved! i am using STM32F030CCT6 MCU. i want to know the internal pullup and pull down resistor value for GPIO pin.
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
Resolved! I have a doubt about memory addresses ¿Any expert?
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 memor...
why external crystal oscillator not working in STM32H7?
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...
How does the USART 2 transmit signal output from pins PA2 and GND to a logic analyser?
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...
Debug and driver folders are not created in code generation
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.
A problem with __HAL_GPIO_EXTI_CLEAR_IT on Nucleo-F410RB Optimization -03 (stm32cubeide)
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...
How to change channel of TSC?
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...
