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...
I2C Repeated Start to put MB85RC512T to Sleep mode
Hi,I am interfacing an FRAM driver from STM32L452RE using HAL lib. mem_read operation is not sufficient to put the FRAM chip to sleep mode. This requires a restart condition as follows:[Start][0xF8][Ack][0xA0][Ack][Rep Start][0x86][Ack][Stop]Here I t...
SPI External Flash Loader for STM32F407VE
I am trying to create external flash loader for STM32F407VE. The flash is w25q64jv - 8MB.I tried to follow the tutorial but since this is QuadSPI and I think STM32F407VE does not support QuadSPI.https://www.youtube.com/watch?v=XqCq0xtQmbI&list=PLnMKN...
