STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on May 25, 2015 at 20:51 Hallo, I try to read the ADC but get allways 0 als result :-( Does anybody have an Idea whats wrong? GPIO_Clk_Enable(@GPIOA_BASE); GPIO_Config(@GPIOA_BASE,_GPIO_PINMASK_All,_GPIO_CFG_MODE_ANALOG or _GPIO_...
Posted on December 16, 2014 at 14:35We constructed a board using STM32F429. We use SDRAM for memory of LCD and NAND flash for program data. SDRAM and NAND flash share FMC bus of MCU. We have 2 problems at present: 1. When we access NAND flash, there...

Posted on May 26, 2015 at 11:57Hi, I have problem with ADC1 conversions on STM8S-Discovery. I have configured the analogic inputs following: PB4 - AN4 PB5 - AN5 PB6 - AN6 unsigned char ADC_Config_INT ( void ) { GPIO_Init(ADC_PORT,ADC_15V_PIN, GP...
Posted on May 26, 2015 at 13:25I'm trying to get data from Invensense MPU9250 with I2C on SC1 of stm32w108.These are connected each other with 10k ohm register.But it doesn't get data.I coded as below.Please tell me how to fix.void SCinit(){ ...
Posted on May 26, 2015 at 07:11I would like to use the PWM as clock source for other device. so I want to know the maximum frequency of PWM. As faster the frequency of PWM signal increase, the more the shape of PWM signal become to triangle signal. ...
Posted on May 26, 2015 at 09:49Hello,I am debugging step-by-step my project on stm32f103vd, using CooCox CoIDE, and ST-LinkV2.when I enable whatchdog, the system go then to Reset_DefaultHandler(). I think that's normal no ?and how I can debug step-b...
Posted on April 27, 2015 at 14:42The user manual for the STM32F051 discovery (named UM1525) seems to be gone from the respective http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1848/PF253215. Some kind of meltdown ? #um1525
Posted on May 18, 2015 at 10:19 I'am using three MAX11210 with a STM32L151VDT6 controller via SPI. I only want to read out the CTRL3 register which is by default 0x1E. If i read out the ADCs behind one another i read 0x1E, 0x1E and 0x1F... but n...
Posted on October 29, 2014 at 14:09I have previously used a timer for triggering ADC for sampling using the standard peripheral library. I am now trying out the STM32CubeMX GUI and generating code from it to be used with Keil. I am working on the ST...
