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 March 02, 2015 at 16:06Hi, I'm using an STM32F4 Discovery board. I need to send some coefficients from a PC via putty to a digital audio processor (with which I communicate via I2C). I would like to use either one of the USB ports on the b...
Posted on March 04, 2015 at 11:42 Hello ; We are trying to read ADC1 channel 10 with DMA triggered by TIMER2 at 1khz sample , We tried all the compination to make it work but it never words the ADC always read 3,3volt full scale ; ...
Posted on March 04, 2015 at 15:18Hello, I want to read several voltages with the adc of the STM32L051K8. If I convert only one channel, then the value is correct, but if it convert several channel is has an incomprehensible behavior. Sometimes it sa...

Posted on March 04, 2015 at 10:22I am still an STM32 newbie, so I apologize in advance for potential dumb questions.I recently installed ST-LINK Utility 3.6 on a workstation running Windows 7 and need to erase and program a couple of ARM Cortex mic...
Posted on March 03, 2015 at 21:57I am using the STM32F429IIH6 for a project.I have 3 ADC channels. Two are working properly, but one is consistently reading 15% low (compared to a DMM). PC2 is the pin not working properly.e.g., when I read the ADC...

Posted on March 04, 2015 at 13:59Hello, is it possible to start 2 timers exactly at the same time? If I enable first timer and then enable the second timer, it takes some time... Thank you for answeres and ideas.
Posted on March 04, 2015 at 11:01Dears, I plan tu use an eMMC memory chip with an STMF32f207 connected to the SDIO interface (4-bits wide) and an FAT lib (from ST). The eMMC choice is dictated by wear levelling and ECC management facilities. All the...
Posted on March 20, 2014 at 06:11Is there EEPROM emulation in STM32CubeF4?Page http://www.st.com/web/en/catalog/tools/PF257902 has status NRND and recommends use STM32CubeF4, but I don't see EEPROM emulation in those bibls
