Hello,I just test some interrupt stuff with Nucleo F439ZI and found that simply setting optimize to -Ofast leads to a timer 2 interrupt (compare event when generating a PWM) firing two times, while -O0 shows the expected behaviour. I test this with a...
Hi there. I'm trying to generate a Pwm signal using my nucelo board but I'm having issues doing this using cubemx. I've configured the clocks and oscillator based on resources I've found online but I'm not too sure what the clock source should be. I...
Hello everyone, I try to disp float value on TFT Screen with STM32F429ZI. But, sprintf function is not work. Can you help me ? please.float fff = 0.85; char s_TextMsg[20]; sprintf(s_TextMsg,"%.2f",fff); snprintf(s_TextMsg,20,"%.2f",fff);...
hey there,I bought me STM32 ST NUCLEO-L432KC for getting more into ProgrammingMicrocontrollers.In School i have already Programmed an ARM Coretex M3 Development board.There i had a Manualwith descriptions of the Controllers Registers, and how they ar...
Hello,I have STM32F746G-DISCO Discovery Board from ST. I have worked on USB, microSDCards and I2C GPIO etc with STM32CubeMX with Keil. Now I want to take some experience on Graphics TFT with Touch with GUI Builder..I have seen some video on emWin — I...
Hi All,I've implemented STOP mode with the following code: (Taken from https://www.digikey.com/eewiki/display/microcontroller/Low-Power+Modes+on+the+STM32L0+Series)void EnterSTOP(void) { PWR->CR |= PWR_CR_CWUF; // clear the WUF flag after 2 clock ...
How can I programming the external flash in high speed?I programming the emwin file use 2min 30 sec, data size is 15Mbyte.Have any solution to make programming fast?Thanks All
I am a bit confused with this setup but hopefully someone can enlighten me with the correct approach, I have an MCU based system and I need an LCD, unfortunately, it needs TFT controller thats why I add STM32F746 in the middle. hope someone can corre...
