Posted on December 18, 2014 at 11:40Yet another bug / gotcha with the SPL...FLASH_OB_GetUser() shifts the User option bits right 20 bits, which means that if you try to compare against the OB_IWDG_SW/HW, OB_STOP_RST or OB_STDBY_RST constants, you'll...

Posted on December 17, 2014 at 20:11Hi friends, Is it possible to handle 1553 bus with stm32 series microcontrollers without using asic or fpga (ip core). For CANbus there are can trancievers that can be directly connected to mcu in the circuit, but...
Posted on December 17, 2014 at 17:43Hello, I'm trying to debug a simple test program (http://developer.mbed.org/teams/ST/code/Nucleo_blink_led/) on my Nucleo board. I've successfully compiled it using GCC-ARM (arm-none-eabi-gcc), flashed my device o...
Posted on November 20, 2014 at 12:47I am trying to get lowest power mode(in stop mode) of STM32L151RB. According to datasheet, power consumption in lowest achievable mode is below 14uA. But I am getting 40uA minimum on my device. I have tried differ...
Posted on December 17, 2014 at 15:49 In stm32l1xx_flash.c, there is a function FLASH_Status FLASH_OB_RDPConfig ( uint8_t OB_RDP ) which is used to enable program memory read protection. Per RM0038 ( http://www.st.com/web/en/res...
Posted on December 01, 2014 at 22:49I'm stuck on TIM triggered DMA to SPI. My DMA Code configuration is as follow: void DMA_Configuration(void) { DMA_InitTypeDef DMA_InitStructure; /* Enable DMA1 clock */ RCC_AHBPer...
Posted on December 16, 2014 at 14:15My company has developed a board with a STM32F207IG and RMII ethernet which is working fine. Now they have given me the same board with a STM32F439II fitted, and here I can not get the ethernet to work. The CPUs s...
Posted on December 15, 2014 at 16:52Hi, I am using STM32L152. I programmed some timers to output a repeated burst of pulses without any software interaction. Now I want SPI to transmit data from a buffer, one 16 bit word at each pulse, and repeat th...
