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 20, 2013 at 13:04Hi, I need to put my card STM32-P103 standby I test the consumption of all the card I see that it uses up to 19mA but the literature indicates that standby power consumption must be to some uA. here is my code: #includ...
Posted on June 25, 2013 at 09:07Hi!I try to test my firmware on STM32L152-Discovery. I'm creating low power application with ADC and SD card. Everything works perfectly, but now it's time for current reduction. When there is no need to do ADC conver...
Posted on June 25, 2013 at 07:50I am using STM32F205RTB6 with internal oscillator (+- 4%), & APB1 peripheral is clocked at 30Mhz.So max variation in it is 28.8Mhz to 31.2MhzI have to operate I2c in fast mode.Now while configuring CCR register , I ha...
Posted on June 21, 2013 at 11:13Page 164 of RM0033 shows that EXTI0 can be used for Px[0], EXTI1-Px[1]... and so on only.That means if I used PA0 pin as interrupt somewhere then I can used PB0, PC0... pins as interrupt source any more???

Posted on June 25, 2013 at 02:53 Hello, I am having some difficulties getting my uart code to work. Can someone please tell me what I am missing? I must have spent too much time looking at it and am missing something very obvious because I h...
Posted on June 24, 2013 at 20:13Dear all,I am starting work on a pre-existing STM32 codebase. There are dependencies on what is called ''stm_lib'' in our source tree, which contains files such as:misc.hstm32f10x_dbgmcu.hstm32f10x_exti.hstm32f10x_gpi...
Posted on June 24, 2013 at 05:11Hello, guysI'm working on a stm32f407 chip and I wanna implement the I2C communication with it. But I have encountered some problems.The following describes my configuration about I2C:Enable clock for GPIOB and I2C.Re...
Posted on June 24, 2013 at 18:01I have a project I have been working on and the coding has been fine up until now. When I upload the code it verifies and starts up without any problem. But If I reset the device (either by reset button or power cycle...
Posted on July 24, 2012 at 17:32 Hey all, Got a small problem when interfacing with a UART based oLED display. The display returns 0x06 or 0x15 after it has received a command, I can see this happening on my O-Scope and I have confir...
