Resolved! STM32F103 RTC calibration issue
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...
STM32F417 CAN Filtering
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...
Resolved! How to get a list of MCUs supporting Firmware update over the air ?
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 ?
how to config ADC conversion to be aligned with Timer comparator edges?
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...
What FMAC can do?
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 .
Resolved! RTC digital smooth calibration doesn't seems to work (stm32l083rz)
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...
Resolved! Timer slave trigger polarity for input capture
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...
Resolved! RM0090 SAI description flaw
RM0090, SAI chapter:Each FIFO word contains one audio frame.This is incorrect. The correct formulation can be found e.g. in RM0410:Each FIFO word contains one audio slot.Thanks,JW
How to read sensor data from the B475E-IOT01A board and send it to a Ublox board through the UART protocol?
I have a B-L475-IOT01A Discovery Board which I would like to get its accelerometer data from and transfer it to a Ublox EVB-ODIN-W2 board using the UART protocol. Is there a guide on how to do this?
