New possibilities for the ultra-low power segment!

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...

STM32L-Discovery - ITM_SendChar lost chars

Posted on March 12, 2017 at 23:30 Hi, I used to use the ITM_SendChar with STM32F3 Discovery board in the past with no problem. === Now I wanted get an text output from another VCOM-less board - the STM32L-Discovery. I configured the S...

Resolved! ADC synchronization to TRGO2 and TIM break

Posted on March 10, 2017 at 15:03On STM32 F7 I'm using ADC injected conversions triggered by TIM1 TRGO2 signal (OC5 rising).In case TIM1 break2 is triggered what should happen to ADC injected conversions? Will break2 disable all PWM outputs includin...

YCbCr conversion to RGB565

Posted on March 13, 2017 at 09:12Hi I am working on STM32F769i-Eval board.I am getting data in YCbCr and provided to MCUMCU accepts YCbCr data but to display on the LCD, DMA2D converts RGB565 to ARGB8888.Now i need to convert YCbCr data to RGB565 to...

Resolved! STM32L152 ADC with TIMER reads only once

Posted on March 08, 2017 at 11:54Im trying to read a battery voltage with a  STM32L152, using timer 2 to trigger the ADC. I can see Timer 2 running (by toggling a LED in the TMR2 interrupt routine) but my ADC only reads once (when the circuit initia...

ADC use different channels at different time

Posted on March 08, 2017 at 02:42Hi! I got a problem when I was dealing with ADC. I am wondering if I need to use the multichannel at different time, which means I want to start one channel at a time  and get a thousand ADC data then stop ADC,after ...

STM32F091 option bytes programming problem

Posted on February 26, 2017 at 12:32Hi everybody,I am facing a rather strange problem when trying to program the two user option bytes (0x1ffff804, 0x1ffff806).The code I am using is rather straightforward:    volatile FLASH_Status test3;    volatil...

STM32F746 Quad SPI in Legacy mode

Posted on January 18, 2017 at 12:52I'm working on project involving STM32F746 in QFP208 package.Reference manual states that in Legacy SPI mode (which may be used for compatibility purposes) pins are configured as:• IO2 is in output mode and forc...

F334 SPI DMA and endian issues

Posted on March 10, 2017 at 14:46Hi,Continuing my saga on SPI DMA, which works now.The idea is to use it to drive a SPI LCD, an ILI9341 with DMA.I see that I can communicate with the LCD, but all 16 bit writes are messed up due to SPI write with 16 ...
