I'm using stm32f429 Discovery board and I want to know number of cycles required to execute this part of assembly code .ldr r3, [pc, #64] ; (0x8001228 <TIM1_UP_TIM10_IRQHandler+120>)ldr r3, [r3, #0]ldr r3, [r3, #36] ; 0x24ldr r2, [pc, #64] ...
Hi,I need to enable interrupts for pins PJ0, PJ3, PJ4 and PJ5. Why these pins? Because they are connected to the ARDUINO connector (CN5 and CN6) of the STM32H7474I-DISCO board and they all seem to be all free. I have the initialization code (Hopefull...
Hi,I'm started to develop on the NUCLEO-14 F746GZ board recently. My question is: it's possible to read input from device (in particular NFC reader MOD-RFID1356MIFARE) through USB CN13? I tried but the device is not powered. Thanks for your support
Hi everyoneI have a system that uses a STM32F205 to sample on a signal at 2MHz. I wanna generate a signal that indicates the sampling times of the ADC as im battling with some frequency differences in my system. Interrupts are sadly not an option as ...
STM32L432I'm using interrupt mode HAL driver and the i2c slave responses successfully for many transactions but then will randomly hang. Here is the code I'm using, its fairly simple.volatile uint8_t i2cbuf[2] = {0, 0}; static void MX_I2C1_Init(voi...
Greetings,I am using STM32L431RC MCU, and I'm trying to read the MUX for reading temperatures using I2C 3 interface, by using the Device address of the MUX, Acknowledge from the device and my data as the parameters in the format as specified in the i...
I'm studying a registers...I have stm32407vg and the LED is on the 'PA1' and I need that the LED turned 'On' after command witch It should turn it 'ON'. In may case after line № 18.But 'LED' turns 'ON' after line №16 and turns 'OFF' after line № 18Co...
Hello.I discovered a weird phenomenon that some flash memory of the board that I have is always the last status is 'FLASH_ERROR_PROGRAM'.The MCU of the board is STM32L152VD.I download my code that checking the last status of flash memory. (It used S...
Hello1628027999 should mean 2021-08-03 23:59:59,at least from a website that does not claim to keep in account any time zone,so I guess(wrongly ??)that it is referred to 0° Longituderawtime= 1628027999; gmtime_r(&rawtime_t, &my_tm_struct);it returns ...
Hello,By documentation STM32F101VC has 32KB RAM, we notice that our project use 44KB of RAM more than 2 years without any issues. What is real RAM size and why in documentation is only 32KB?
