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...
Posted on December 15, 2014 at 02:55Hi,How can i link 2 different hex files at 2 distinct memory locations?for example at 0000h i have my main code and at 4000h i have my application code. app code must access the functions in main code, so since i ...
Posted on December 16, 2014 at 12:39Good morning there is someone who has found the whole chart of the values, of the SPI_CRCPolynomial ?? like: SPI_InitStructure.SPI_CRCPolynomial = 7; I have see 7 the most useful value, but who knows the oth...
Posted on December 16, 2014 at 15:58hi everybody, as far as i understood the data in the RTC registers are lost after a hardware reset or the power is lost. So the next idea is to use a battery as a backup. But after reading the data sheet and refer...
Posted on December 16, 2014 at 14:16I have a problem of crosstalk between sequence channels scan automaticly on the ADC3,2 of the MCU. It is look like it is depend on the sequnce of the sample becase the voltage changes on the first scan channel inf...
