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 17, 2014 at 03:23I want to transfer data between USB HOST MASS STORAGE CLASS ( STM32F4DISCOVERY (MCU : STM32F401VCT6U)) and USB DEVICE MASS STORAGE CLASS (STM32F4DISCOVERY (MCU : STM32F401VCT6U)).I generate both project from STM32...
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...
