I'm trying to enter STOP2 mode to save energy but the MCU get stuck in the function HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI). I have cleared all EXTI pending flags and RTC flags, and disable all five wake up pins. The MCU is supposed to wake up vi...
I use STM32F102 and TIM2 timer in PWM1 mode to generate defined frequency and duty cyclesquare wave. I have some questions and I hope can get some help from experienced colleagues.1. I update the ARR/CCR1 register in an interrput which is defined by ...
I have done some investigation and arrived that the problem is with the "DIR" bit in the Interrupt Status register not firing to indicate whether to do a Read.uint32_t isr_trace[64]; int isr_count = 0; void I2C2_EV_IRQHandler(void) { isr_trace[...
Even though most of you may be relatively familiar with the various types of mechanical controls, the same does not necessarily apply for capacitive ones. So, let’s start off by defining the most basic elements of capacitive sensing.Capacitive button...
Hello!We have choosen the STM32F407/427 for our product, a couple of years ago.It fits with the speed, and also with the possibility to use DMA for mutliple peripherals.Now, as we have found out the hard way, the DMA2 fails while handling ADCs and SD...
Hello,I've been using STM32F051C8 on some of my projects and I recently realised that, my ADC is not converting accurately. I connected my Vdda to Vdd, that is 3,3VDC and tried conversation routine below.Here is the initialisation: Single Channel con...
I would like to dump all Cortex-M4 registers of my STM32F405 microcontroller over a UART. I have found the Technical Reference Manual (https://static.docs.arm.com/100166/0001/arm_cortexm4_processor_trm_100166_0001_00_en.pdf) but there are tons of reg...
I'm reading ADC1 and ADC2 in Dual Regular Simultaneous mode using DMA on a F334R8 nucleo board, as per instructions in UM1786 section 6.2.2 "Execution of ADC conversions":void readADCs(void) { // enable ADC slave if (HAL_ADC_Start(&hadc2) != HAL_...
