Resolved! I have an STM32F429 Discovery kit.and can't find a MOOC or Online training on ST site. Which can I use?
I have an STM32F429 Discovery kit. I would like to go though a MOOC or STM32 Online training mentioned @ https://www.st.com/content/st_com/en/support/learning/stm32-education.html. However, I don't see any for that board. Are any of the posted resour...
Resolved! STM32F373 RTC is accurate with VBAT but not when power is on
The RTC looses 15 min every 8 hour aprox when the main power is on. I have selected the LSE as the RTC clock, as i show in the images, and i have a 32.768 Khz 10 ppm crystal with a 9 pF load. I thought that maybe it was due to a bad match of the crys...

F4 loops bug in O3, runs fine with O2
Hi, I'm having the weirdest bug with this code. It's just 2 for loops expecting to count from 0 to 5 and 0 to 8.When compiling with O3, i becomes very high and the execution gets stuck in the loops. Running STM32 Cube IDE 1.9.0STM32Cube FW_F4 V1.27.0...
hello how can i convert the values i get from multiple ADC to multiple PWM signals again
Hello, I'm new to embedded system programming. I'm trying to turn 2 LEDs on and off with 2 potentiometers. But every time I turn a potentiometer, the LEDs flash at the same time. Can you help me with this?void ADC_oku() { HAL_ADC_Start(&hadc1); HA...
Resolved! Need to send data like {0x01, 0x00, 0x00, 0x00} or 0000000100000000000000000000000 using NRF24L01+ and process it on receiver side. How do I achieve it ? I'm using STM32 G030C6T6 IC. Please help I'm a newbie. Thank you
I'm using https://github.com/elmot/nrf24l01-lib library for communication. For now I' able to send strings like "helloworld" and process them.
Resolved! Is STM32H725 VTOR bit assignments is not correspond ARM7M arcitecture?
Hi!ST manual PM0253:[31:9] TBLOFF Vector table base offset field. It contains bits [29:7] of the offset of the table base from the bottom of the memory map.[8:0] - ReservedArm v7-M Architecture Reference Manual:Bits[31:7] of the vector table address....
RTC can get corrupted and always requires a backup domain reset.
I'm using STM32L433 and what happens on rare occasions is that the RTC somehow gets corrupted and runs at 60% of its normal speed. Software resets do not fix the problem. I finally figured this out, it requires a backup domain reset. This is the code...
Is there a limit to the number of GPIO that can have interrupts within an EXTI group at one time?
I'm using an STM32H7B3I-DK. Using CubeMX, I'm trying to add rising edge interrupts on PI10, PH10, and PF10. The board uses one interrupt for WAKE_UP already. But, every time I go to add the third GPIO, it takes off a previous one and returns it to th...
