Posted on June 06, 2018 at 07:56Hi, Regarding our development board using STM32F745VG, we would like to add QUADSPI FLASH in next our PCB board. But some QUADSPI_BK1_IOx(PE2 and PA1) are already connected to Ethernet IC. And QUADSPI_BK2_IOx PINs are...
Posted on June 06, 2018 at 07:41I have a 32 gb sd card. I have interfaced it with STM32F407 Discovery board with 1 bit SDIO through Cubemx. When i use a formatted SD card i am able to write files into the card. Now, i want to format the card using s...
Posted on June 01, 2018 at 05:07Hello all,I'm here using the M95640 EEPROM and communicating via SPI. It looks like I'm sending all the signals correctly from my MCU side, but the device (M95640) is not responding to Signals.Below is the WriteEnable...

Posted on June 06, 2018 at 00:00I'm doing frame buffering exactly as that guy doinghttps://gist.github.com/postspectacular/61f17333c17b0206a73e4591cd5ce59bThe problem, I'm cloning flappy bird, and at the top edge of the screen, I get a background th...
Posted on June 05, 2018 at 20:27hello everybodys , i'm trying to program stm32f072 from stm's bootloader through i2c interface. the stm32f072 is the slave board while the another MCU is the Host/Master board. The host Board use the Simulate i2c on ...
Posted on June 05, 2018 at 18:27Hello,I'm currently testing low-power modes on my MCU and I need to know if it's possible to wake up from stop mode via peripheral interrupts (timer, I2C, USART, ADC and so on)? Reference manual says that all the PLLs...
Posted on January 26, 2017 at 16:00Hi,The QSPI peripheral in the STM32F7 is wonderful. Nice job ST!One question: Is there any way to exit memory mapped mode and go back to indirect RX/TX through the HAL driver?Thanks!Bobby
Posted on June 05, 2018 at 19:57Hi there,I have generated USB CDC code from cubeMX for STM32F207ZT (144 pins) nulcleo board and it is working fine USB device is getting listed in COM ports. Now I am flashing the same code with some minor clock chan...
Posted on June 05, 2018 at 11:54Hello there,I found some differences between the memory mapping of the Datasheet and the Reference Manual:DS STM32F4x Rev10 - Memory map pg. 86Option Bytes 0x1FFE C000 - 0x1FFE C008Reserved 0x1FFE C00F - 0x1FFE F...
