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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on May 22, 2014 at 00:23Hi,I'm using STM32F429 and working with the lcd. i want to display a string horizontally at lcd. First i have used the segger's gui, it was easy to display horizontal with using gui. But i decided to use the lcd.h for...
Posted on May 21, 2014 at 12:57Hi, i'm working on stm32f429 with keil uvision v5. I came up to some discussions about debug viewer at keil forums(like this http://armcortexm.blogs.upv.es/stm32f4-discovery-and-printf-redirection-to-debug-viewer-in-ke...
Posted on May 20, 2014 at 01:21hello I am using STM32f100C8 on this controller implemented : Tim4 that work as global clock for all the functions (generating ticks and counter with flags compare to seconds )Tim3 work as PWM but it implemented man...
Posted on May 21, 2014 at 19:53Hey, I am using STM32F405 as the controller in my project. We have hundreds parameters needed to be saved in the Flash memory and this parameters will be modified one by one during the running. The problem is the flash...
Posted on May 23, 2014 at 13:20I am using STM32F205RBT6 & have to make it battery operated . So lowest power consumption is desired.What should be setting for:1. Prefetch buffer : I have turned off2. Instruction cache : I have turned off3. Data ...
Posted on May 24, 2014 at 11:45Hi everyone, I'm trying to implement I2C1 on stm32f4-discovery to let the kit contact with a light-to-digital sensor TSL2581CS ..In the following code, the <b>I2C_CheckEvent(I2Cx, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELE...

Posted on May 15, 2014 at 17:06 Hi, I am using uvision4 with stm32f1xx to meansure frequency counting the time of the falling edge pulse. I need a high precision to meansure frequency from 0Hz to 240Hz. The first thing that I do was to set the pre...
Posted on May 23, 2014 at 20:15 whenever i perform the dma transfer, I always get a transfer error on the write to TIM1->BDTR. If I write to a different peripheral register, such as TIM3->ARR, it succeeds. Any thoughts? TIM_TimeBaseIni...
Posted on May 23, 2014 at 16:07One thing I have not been able to find in the datasheet: if the FSMC is being used to access 16-bit memory, what does A0 do? I'm a bit confused about this. If BCR.MWID is 00 => 8-bit data width, you have to address ind...
