Posted on August 28, 2015 at 22:56HI guysI can simply not see why this is not workingvolatile _Bool DitOn = 0;volatile _Bool DahOn = 0;void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ BSP_LED_Toggle(LED1); if(HAL_GPIO_ReadPin(GPIOI,GPIO_PIN_2) == GPI...
Posted on August 18, 2015 at 07:18I have been trying to use the latest HAL drivers, make thing easier once you understand their complexity. I am up to trying to get the I2C port working. i have no activity on the I2C bus at all the pins remain high ...
Posted on August 30, 2015 at 20:03Hi, as specified in the topic, I'm trying to create my own wave file player using f4-discovery board. I've managed to configure the DAC, read the file, find the data section, read the samples and I can hear the soun...
Posted on August 29, 2015 at 19:58Hello,I have some questions (they might seems easy to you, but not to me).Im using a STM32F0 discovery and I want to read the USART2 data with putty.Since the USART2 is not directly connected to the PC, I don't know...
Posted on August 30, 2015 at 17:10Hello,i see that if i activate the bootloader with BOOT0=1 and BOOT1=0 the system stay in the bootloader cycle all the time i mantain the pin configured in this way until restart the cpu. Is possible to jump directl...
Posted on August 29, 2015 at 00:01Hello.I'm having problems with STM32F103 SPI peripheral. On STM32F072 I could have proper transmission with hardware NSS management, but on STM32F103 it is just pulled low and it stays like that.Is there any solutio...
Posted on August 29, 2015 at 07:50Hi, please helpe me for this problem: we program stm32f103 using IARand I wants makes a signal using TIM2 but micro works for one time after programming after turn off power other dont work and stop out signal that ...
Posted on August 28, 2015 at 17:59I've made a PCB which is very similar to that of the STM32DiscoveryF4 schematic but I cannot see the STM32F407 with my ST-Link programmer on either the JTAG or SWD methods.So far I have soldered only an minimum numb...
