Resolved! STM32F1xx: Confusion on CCRx value for a given PWM frequency with TIM1 PWM Output???
I'm using an old STM32F103RD with SPL v3.6.1. I'm confused with the value to put in TIM1_CCRx for a giving PWM frequency.Looking at \STM32Cube_FW_F1_V1.7.0\Projects\STM32F103RB-Nucleo\Examples_LL\TIM\TIM_PWMOutput\Src\main.c: /* Set compare value to ...
Resolved! problem with TIM exception stm32f103
So I just started to use stm32f103 MCU that I have but for some reason I code doesn't go into the TIM2_IRQHandler.This is my code:.thumb .syntax unified .equ GPIOB,0x40010C00 .equ RCC ,0x40021000 .equ TIM2 ,0x40000000 .equ NVIC ,...
STM32F730R8 __FPU_USED needed?
Hello all, I'd like to know if I'm making full use of the FPU on an F730 using SW4STM32/Eclipse. In project properties i set floating point hardware to fpV5-sp-d16 and the ABI to hardware. I also define __FPU_PRESENT & ARM_MATH_CM7 and set the libra...
Resolved! Displaying the value of a temperature on the LCD
Hello everyone, so what I’m going to do is displaying the value of the temperature on the LCD of the STM32F413H-Disco with a PT100, i wrote this code:int value;char getvalue[20];...MX_ADC_Init();HAL_ADC_Start_IT(&hadc1); (I choose Interruption becaus...
STM32F107 I2C2 not clocking the SCL line.
Is there an alternate function that needs to be disabled for this to work by default? The datasheet footnote says "SPI2/I2S2 and I2C2 are not available when the Ethernet is being used." Is the Ethernet enabled by default and how do I disable it or pr...
Resolved! Is it possible to interrupt the middle of a += operation?
I think I have proven now through tests that the and is clearly "YES". But, I'll still put this is as some awareness raising anyway. It might not be immediately obvious that an interrupted task can override the value of an interrupting task. Also, I'...
Resolved! Confusion about memory addressing and byte alignment in QSPI dual flash mode
Hello,I'm a bit confused about how memory addressing and byte alignment works when using two QSPI FLASH memories in dual flash mode.Accordingly to AN4760 paragraph 2.2.4, in dual flash mode addresses are "splitted" across two banks by sending even ad...
Is there a good practice for the NVIC Interrupt table priority ?
Hi,Sorry for my stupid question but I am always in doubt when I give the priority in the NVIC table for DMA, UART, SPI, Timer, ...Is there a rule like for example set all DMA at 0 ?How to know what peripherals must have the highest priority and how ...
