Compilation error with MODSEIAL & STM32F401RE
Hello everyone,Since can I switched to STM32F401RE. Since impossible to compile with MODSERIAL.I’m compiling on MBED StudioMED OS 5.15.7Here is the errorMODSERIAL_NUCLEO_F401RE.cpp:5:17: error: 'struct serial_t' has no member named 'index' switch( _...
What is the value of the input impedance of the OP-AMP inside the STM32U575?
Dear ST,I am trying to configure a voltage follower usin intenal op-amp for external voltage monitoring. And we are going to read that value through ADC.Therefore, it is necessary to select the resistance value of the voltage divider.So I want to kno...
MCU:STM32G0B1 fails flash page erase with HAL_StatusTypeDef HAL_FLASHEx_Erase(FLASH_EraseInitTypeDef *pEraseInit, uint32_t *PageError)
Why using:/* Fill EraseInit structure*/ EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES; EraseInitStruct.Banks = FLASH_BANK_1; EraseInitStruct.Page = StartPage; EraseInitStruct.NbPages = ((EndPage - StartPage)/FLASH_PAGE_SIZE) +1; /* F...
I2C HAL_I2C_Mem_Read ( ) failed
Hi,I am working on I2C read EEPROM. The HAL function failed due to the I2C_FLAG_BUSY is always SET.Is there anything I am missing in init code?Thx if (I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_BUSY, SET, I2C_TIMEOUT_BUSY, tickstart) != HAL_OK) { ...
STM32G030 UART_DMA
I'm trying to 500ms once transmit 5 byte of data. but 2 byte of data only transmit . below i given my code . i don't know where i made mistake if any one know help me.UART_HandleTypeDef huart2; DMA_HandleTypeDef hdma_usart2_tx; DMA_HandleTypeDef hdma...
STM32F429ZIT6 Encoder Mode not counting
I have a custom PCB with a STM32F429ZIT6 on, I am using CubeMX and STM32CubeIDE.The board generates encoders signals with TIM1 & TIM3 in Output Compare mode.I can scope and see the correct encoder signals being generated by both timers.Then, I also w...
NVIC and Piority Grouping in STM32 after reset
Hi.I have in my hand Nucleo with STM32F103 (old uC but to understand grouping newer is not needed).In Programming Manual PM0056 on page 134 and 135 I can see a SC_AIRCR register which on PRIGROUP field at reset are all zeros, but on next page in tabl...
Resolved! UART + DMA and IDLE line interrupt with HAL layer does not work as expected
Hello,I am trying to update some code to use UART with DMA for receiving instead of the polling method.I want the implementation to work for messages of unknown length so I use the HAL_UARTEx_ReceiveToIdle_DMA function.I know that the maximum message...
Resolved! WUF flag when exiting Standby
Hello.STM32G070CI'm having some issues with the WUF flag when exiting Standby. Exit mode is set to WKUP1 (PA0).I poll the register after exiting standby and in the PWR->SR1 register, the SBF flag is set, but the WUF1 flag is cleared.I also noticed an...
