Having problem getting wifi to accept appassword

Good Morning, I am running my STM32F4 microcontroller application in the μVision Keil simulator and the target debugger.   Is it possible to retrieve the values of some variables on a chart or table on my PC?

STM32L452 + SD + DMA + FATFS + STM32CubeMX v5.0.0: DMA and SD interrupts can signal end of transfer before it's complete

We are using an STM32L452, running directly from an HSE crystal at 8 MHz (i.e. no PLL), using the SDMMC peripheral with an SD clock of 8 MHz, and DMA for transferring data to and from SDMMC.When the DMA part of an SD read is complete, HAL_DMA_IRQHand...

Can we control RTS/CTS signle for Hardware flow control support for LPUART of Stm32l4r5?

Hi,We are using LPUART port of the STM32L4R5 controller for communication with BLE for that we would like to use RTS/CTS signal.How can i control/check the RTS/CTS signal?Is it possible to control/check the RTS/CTS signal through the software?Please ...

STM32L4 + SD + DMA @ 8 MHz: read failure due to missing byte.

We are using an STM32L452, running directly from an HSE crystal at 8 MHz (i.e. no PLL), using the SDMMC peripheral with an SD clock of 8 MHz, and DMA for transferring data to and from SDMMC.We're also using the SD, DMA and FATFS library code generate...

STM32F4 HSE clock frequency without HSE

Posted on April 12, 2018 at 02:23I am using an STM32F446ZE Nucleo Board which does NOT have an external HSE clock. From CubeMX I set the clock input from the HSE and after in the clock configuration I set the system clock to 180MHz.https://i.stack.i...

Error compiling for board Nucleo-64 with Arduino IDE

Hello,I tried to compile the simple "Blink" sample with the Arduino IDE, but I get always an error:Board Nucleo_64 (platform stm32, package STM32) is unknown Error compiling for board Nucleo-64.I installed the latest Stm32 Cores (1.3.0) via the Boa...

Does erasing erased sectors in flash count as a write/erase cycle?

The reason why I want to know this is the following:We used AN3969 to create a EEPROM emulator in flash on an STMF407. After 1 to 4 years, we saw that on a minority of appliances (less than 0.5%) the emulated EEPROM was erased and the data written to...
