I have a need where, to execute certain action depending on duration of button press.Example when press from 100ms : Play Song, 200ms : Next Song.I want to know what is the smartest way to implement this so that the user experience is good in the con...
Posted on May 02, 2018 at 12:34I know this is an old problem but I really cannot figure out.My intention is to use timer 15 as a trigger source with setting equal to 1kHz. Then by enabling ADC interrupt using EOC flag I think I could have an ADC in...
I used STM32CubeMX to build a very simple test case to output both the High Speed Clock (HSE) and Low Speed Clock (LSE) on output pins. I selected "Master Clock Output 1" and Master Clock Output 2" when I configured the input clocks. The HSE clock ...
Hi everyone!After AVR mcus STM32 with Cube and HAL is like an oasis in the desert! But after many experiments, researches and sleepless nights I know the situation isn't so great as I thought.I have few boards with 100, 103, 407 and other series.I'm ...
I do not want to use the USB part of the STM32L082. According to the Ref Manual RM0376 page 140 there is no explicit mention that the VCC_USB can be tied to GND if not in use. So what would be the thing to do (and reduce the power even further): GND ...
Posted on February 28, 2013 at 04:03A am using STM32F103T4, a low density device, and want to use the re-mapped SPI1. Below is my implementation: /* GPIO and AFIO clock enable */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO| RCC_APB2Periph_GPIOB, EN...
Hi,Using the following code, ADC can be triggered by TIM22 successfully./** * @fn static void ADC_Config(void) * * @brief ADC configuration. */ static void ADC_Config(void) { /* Enable clock */ RCC->AHBENR |= RCC_AHBENR_DMAEN; RCC-...
I am working on a hard fault handler were I want to store some key values into ram before resetting. This data will then be further handled at next boot up.My problem is that the data does not get written into RAM unless I step through the writing co...
The STM32F4xx reference manual (RM0090) specifies under the GPIO main features section that there are "up to 16 I/Os under control" - does this mean I cannot control more than 16 GPIO pins or am I interpreting this incorrectly?
