Posted on October 26, 2015 at 15:56Hello, what is Half-cycle access (FLASH_ACR_HLFCYA) for? It may be used with slow clocks ( < 8 MHz) and AHB divisior = 1.
Posted on October 11, 2015 at 15:24 Hello, I tried to test the I2C interface on a STM32: #include <stdio.h> #include <stdlib.h> #include ''diag/Trace.h'' #include ''stm32f4xx_hal.h'' #include ''stdint.h'' int main( int argc,...
Posted on October 26, 2015 at 20:20Hi,I have connected two MCU's through UART.I want to send a string from MCU 1 to MCU 2.once the MCU 1 sent the string it need to wait for some time to receive the reply from MCU 2.If MCU 1 did not get any reply fr...
Posted on October 08, 2015 at 10:48Hello, I failed to get an application with USB-Host and FatFS working with CubeMX. Does anyone has an example project? FatFS always reports fr_disk_error. I founds some posts with similar problems in some boards bu...
