Posted on January 06, 2015 at 11:20Hello, the STM32L0 series sets nearly all GPIO to analog mode as default. This does make sense opposed to the ''default to input'' on other family that may result in high current draw with floating inputs. Only Por...
Posted on January 04, 2015 at 04:11My project involves using a STM32L152 part as a SPI master that receives data from a slave (digital accelerometer). When I look at the SPI signals through a scope, I notice that the incoming SPI data is being inter...
Posted on January 05, 2015 at 14:21I have a new STM32f4 Discovery board and would like to be able to build, burn, debug programs in Ubuntu linux version 14.04. I basically followed these directions: http://www.wolinlabs.com/blog/linux.stm32.discover...
Posted on January 01, 2015 at 09:39Hello, hapy 2015 to all. I try to use an external LSE for RTC a STM32F4DISCOVERY . I follow indication of clive1 on this post: https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/Flat.aspx?RootFolder...
Posted on January 04, 2015 at 17:09hi, STM32F103C8T6 Minimum Board after system reset NRST or power reset not run(blink LED). After core reset in ST-Link utility window MCU runs to next hardware button reset. Can any help me please #reset-stm32
Posted on January 04, 2015 at 09:22Dear friends.My platform is STM32F429Discovery.I encountered whit Hard Fault error. I used the code of Joseph Yiu to track the place where error occurs. It is in the portasm_cm4.s (FreeRTOS). ldr r0, [r1]r1=0x03FF...
Posted on January 03, 2015 at 13:50Hello all, I just began working on an old project which had some problems that had not been solved, of which I did manage to pinpoint (in relative terms) the source. Developing platform: Keil uv4 Chip: ...
Posted on January 04, 2015 at 13:09We are building a digital LED buck converter with slope compensation as described AN4885 High brightness LED dimming using the STM32F334 Discovery kit.The discovery kit application uses the DAC to generate a 250 kH...
Posted on December 28, 2014 at 22:41Does anyone know if it's possible to enable the DAC without having it drive the corresponding output pin (PA4 on STM32F301 in my case)? I want to use it as a reference for the internal comparator, but unfortunatel...
Posted on January 02, 2015 at 14:28My STM32F429 board uses Kingston 4GB uSDHC card. CubeF4v1.3.0 HAL init fails in SD_PowerON() function in stm32f4xx_hal_sd.c /* Send CMD55 */ sdio_cmdinitstructure.Argument = 0; sdio_cmdinitstructure.Cmd...
