Baud rate problem
Hi, I am using STM32F767ZI. I am working on UART communication of STM32F and other MCU. But I have a problem. Other MCU 's baud rate is 125K, 250K and 1M. Do you have any suggestions about this? Thanks to answer.
Resolved! Change the status of a variable when a button is pressed via interrupt routine.
I am implementing an application when I need to set high a status variable when a button is pressed. I would like to do so via the interrupt routine of the push button. So, in gpio.c I havevoid HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ if (GPIO_...
Resolved! Can STM32U585 embedded Op Amp could withstand a 150mA pulse current?
HelloI use the embedded Op Amp in STM32U585VIT3Q to charge a 47uF capacitor.The input of the Op Amp is connected to the output of DAC. The voltage level is 3V.So you can see when the Op Amp begin to charge the cap, the peak current is quite large.I w...
Problems with receiving from ESP8266 via UART
Hi,since some days I try to get a communication between a STM32F030R8 Nucleo and an ESP8266 WIFI module working. Communication between Putty and WIFI module works already. I am stucking at receiving the answers from ESP module. I already tryed it wit...

STM32L011 in low-power and "Target is not responding, retrying ..."
I'm using Nucleo STM32L011K4T6 kit to test different low-power features.For this, the code is executed in RAM for 10ms (GPI/Os management) then the MCU is put in stop mode with the WFI instruction, to be woken up 90ms later by the RTC (RTC wake up).T...
