Hi! I have a project in which I tried to enable LTO for release builds. Issue is that the code hangs before entering the main loop. Upon investigation, I found that an interrupt is triggered: the code gets stuck in the default implementation for the ...
I am using STM32L4 series microcontroller. I am debugging some code which uses standard C lib function fopen() and fread(). The code can be compiled and has no errors. For some reason fopen() function is returning NULL pointer when used. I wanted to ...
How to calculate capacitor value for 32.768 kHz cystal (RTC for STM32F030R8T6)
Hi,I'm trying to calibrate my RTC by writing on the RTCCR register on an STM32F103 MCU. However, it seems like this is not taken into account as the 512Hz signal is still slightly out.I'm using the following code:PWR-> CR |= PWR_CR_DBP; // Allow acce...
Heei,See figure 342 on page 1088 on reference manual RM0090 Rev 19. It denotes the 32-bit CAN filter register layout. I have the registers configured as described below:F1 register is 0x200000 (bit 21 set). e.g. stdid[0]F2 register is 0x1fe00000 (bit...
Hello, does anybody know where to get a list of MCUs that are able to be updated over the air ? If there is not such a list, what features should I look for on the datasheet ?
Hi, I'm doing motor drive project using F429. I want to achieve ADC triggered by PWM edges and generate interrupt to deal with ADC results, Timer 1 is counting-up mode, so How to configure related registers?ADC triggered at one (only one at one timer...
I want to do averaging, and finding peak value of about 1k ADC readings. I wonder if I can use FMAC to do it to offload MCU .
To read the frequency I am using a timer to output frequency then I am reading the value using a frequence counter. I am using the stm32l083rz chip. I have a gate time of 32 seconds on my frequence counter.I am trying to compensate the drift due to t...
I want to use TIM1_CH1 to measure pulse width. TIM1 works under slave reset mode. The input trigger is TI1FP1. Ideally, TIM1 resets upon rising input, then TIM1_CH1 captures the falling edge. The CCR1 value would be the pulse width. The problem is th...
