Posted on October 07, 2015 at 01:24 I am having trouble getting SPI2 to function on my STM32F407 board. My issue is that I am seeing data on the MOSI pin with a logic analyzer but there is no clock activity (it is low). My processor is clocked at...
Posted on October 06, 2015 at 23:37We are trying to find the pins numbers for each adc channel.We know that ADC1 channel 7 is connected to pin PC1 but can not find information in the datasheets on the rest of the pin pairings. Your help is greatly a...
Posted on August 10, 2015 at 10:14Is there any way to cancel OUT transfer (receive) on STM32 using CubeF4 library?I use USB in my device to communicate with PC (STM32 is ''device'', PC is ''host''). If client (PC side) program is ''crashed'' and my ...
Posted on December 23, 2014 at 19:32I've posted on this before, thought I'd nailed it correct, but did not, as there are inconsistent results. I am using the Discovery STM32F4 development board, along with IAR compiler/workbench. Can someone please ...
Posted on October 06, 2015 at 20:13Hi! I was wondering if clock from RCC to GPIO peripheral is needed other times than accessing GPIO registers. On STM32F051 datasheet it says for example that current draw when clocked is 9uA/MHz on GPIOA and 12uA/M...
Posted on October 06, 2015 at 17:44Hi, I'm relatively new to STM32 series of SOCs and there seem to be pleothra of information on Bootloader and Device Firmware update. These are perhaps the two major reason, why I do not have a clear picture of DFU...
Posted on October 06, 2015 at 17:31I am working on a STM32 NUCLEO 152RE.When initializing a I/O pin of a digital port, one of the options is to set its speed. The available options for L152 are:GPIO_Speed_400KHz = 0x00, /*!< Very Low Speed */ GPIO_...
Posted on October 04, 2015 at 17:49Hi,i am using stm32f105 microcontroller for usb application. i installed stm32cube. and configured but at the end i m confused to select toolchain. Which toolchain is to select.I am using eclipse, so from this drop...
Posted on July 18, 2012 at 22:11Hi I am trying to write date and time to the RTC which I later will read.But something in my RTC configuration doesn’t work and reading the values in debug mode shows that the RTC registers that I try to set never g...
Posted on October 06, 2015 at 17:39How do you put the LCD on the 429I-DISCO board in landscape mode using 320x240 size instead of 240x320 and using the HAL and BSP, not STem? I'm familiar with XY-mirror etc. However, I cant figure out how to create ...
