Posted on January 12, 2017 at 08:18I am using an STM32F407 on a customer board and have trouble with the I2C handling.I am using the latest HAL HAL_I2C_MasterTransmitIT and HAL_I2C_MasterReceiveIT to poll data from a sensor.The problem is that after...
Hello.Can i read state of BOOT0 pin in STM32F030F4P6?My uC always turn on with BOOT0 GND, but i need to have dual purpose pin BOOT0 and have possibility to read only state of this pin.
Im working to use external SDRAM for STM32F746DISCO board and configuring associated FMC register. When ia start to debug i see that all of SDTR (timing) register bits are valued as F. I can write to SDCR and SDCMR registers but can not write to timi...
Hello everyone. I'm studying Stm32 and just starting with kit Stm32f746g disco. I'd like to download Standard peripheral libraries. But I don't see any information about Std libraries for F7xx in google. So I'd like to ask you: have or have not Std l...
We are preparing the design for a board that will be sealed in a system, so connecting a standard USB debugger to the system isn't going to be feasible. We would ideally like to place a circuit on board similar to what the various evaluation boards u...
Posted on July 11, 2018 at 22:34Trying to replicate the functionality of the project example for FatFs_uSD_DMA_RTOS on the STM32H743I_Eval board using CubeMX I have run into the next layer of problems, this one involves the SDMMC clock. There is no...
Posted on May 04, 2016 at 11:36Function returns HAL_ERR if PELOCK bit in PECR is already unlocked, so in my code I changed it into this: HAL_StatusTypeDef HAL_FLASHEx_DATAEEPROM_Unlock(void) { if (READ_BIT((*FLASH).PECR, FLASH_PECR_PELOCK)) ...
Posted on May 16, 2018 at 20:13I try to use SDMMC1 on STM32H743I Nucleo: It works fine but just if I use PLL1: PeriphClkInitStruct.SdmmcClockSelection = RCC_SDMMCCLKSOURCE_PLL;If I try to use PLL2, the PLL2R clock output via: PeriphClkInitStruct.Sdm...
Hello everyone. Can anynone please explain the steps to configure linker script to use external SDRAM? I'm using Atollic True Studio as IDE and STM32F746GDISCO as evaluation board.Thank you.
