Posted on April 16, 2014 at 03:34I understand it is used to detect whether a device is connected or pulled out. But I have no idea how. So my questions are as follows: 1,How exactly does that pin work? 2,I can use whatever pin that is five tolerant ...
Posted on April 15, 2014 at 08:14When I was trying to use the official USB host library I came by this func: USB_OTG_BSP_Init And it has some of these components: /* Configure SOF Pin */ GPIO_InitStructure.GPIO_Pin = HOST_OVRCURR_LINE; GPIO_Ini...
Posted on April 14, 2014 at 15:51Hello, I'm trying to figure out where the factory-calibrated values for internal reference (Vref and Tsense) are located in STM32F10x series. STM32L15x series have a Vrefint_cal and Tsense_cal1/2, but I can not find ...
Posted on April 14, 2014 at 01:23 Guys, I have a question about SDcard and LCD initialization , Everytime I intialize LCD after SDcard, SDcard stopped working, is it because of port clock ? Thanks SDcard initializatio...
Posted on April 16, 2014 at 22:37 Hello forum I've just signed up here since I ran into troubles reading sensor data from an Analog Devices IMU with SPI. I'm still a beginner with the Cortex M4, so maybe I'm missing something crucial... ...
Posted on April 16, 2014 at 10:57I'm currently trying to interface an STM32F4 (discovery) with a telemetry unit (RFM42B if anyones interested) using SPI.The minimum clock time high and time low given in the telemetry devices datasheet for SPI are 40...
Posted on March 25, 2014 at 17:48A wish for new chips: It would be nice if STM could consider to implement a UART which supports bit-wise arbitration, as it is required for KNX / EIB networks. KNX/EIB of course is a big market, but this functionali...
Posted on April 15, 2014 at 07:47Hi I would like to use STM32L062K8 for our low power application. The peripherals we will be using are 1 I2C, 2 watchdog timers(WDI, WWG I think), 1 SPI, 1 UART(RX, TX), and 3 general purpose timer.Timing for asynchr...
Posted on April 15, 2014 at 15:23 I have a snippet which works, it blinks blue LED on stm32f4discovery: void TIM6_DAC_IRQHandler() { if (TIM6->SR) GPIOD->ODR ^= (1 << 15 ); // Toggle D15 TIM6->SR &= ~1; // Interrupt has been handled ...
Posted on April 15, 2014 at 05:04 Hey all, I'm working on a project where I have to process an audio signal in a few different ways. However, I have never done anything of the sort. I have been reading up into how to implement basics such...
