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 April 29, 2015 at 23:18 Dear Community, I’ve investigated the ADC of the STM32L100RC (DISCO-Board) in continuous and in the triggered mode.In continuous mode I was able to reach a sample frequency of ~300 kHz which I investigated exp...
Posted on May 04, 2015 at 01:37 I'm comunicating a nucleo board with a mpu6000 mems sensor, using CubeMX to make initialization code. It is working ok, but with just one issue. I have to write 0x3B|0x80 and a 16 0x00 (dummy bytes) and read b...
Posted on April 30, 2015 at 08:07Hello, I use STM32F407 discovery board and keil uvision4. I want to do matrix communication but I meet the following weird problems. My code is as below. float Num[2]= {0.000144962712488309, -0.000602...
Posted on May 03, 2015 at 16:46Hello, I'm working on custom board using STM32L152 chip. Vref is : 3.19V When i injuct to the analog pin 2.7 i read 4019 ,while 0 represent as 650. (It seemed like 650 is the gap ????) below my initialize ADC code :///...
Posted on May 03, 2015 at 01:46 Hello, I have strange problem with flash programming ''on the fly'' on STM32F411-Nucleo When I use FLASH_ProgramDoubleWord (STD drivers 1.5.0), programming does not work. I know, it says that volt...
Posted on May 03, 2015 at 00:30Hi, I have been looking at this for hours, but cannot determine why I cannot get the I2C3 operating, even getting a pulse from the SCK line. I am using an STM32F4 device, with an ST LIS3DML sensor. Both SCK and SDA are...
Posted on May 02, 2015 at 15:29Hi All,I am using the ADC on the STM32F407VGE to detect water through an infrared sensor. I am getting a very small change between seeing the water and not. With the sensor clear there is 0.1 volts which reads around 1...
Posted on May 01, 2015 at 15:48 hi my rtc is initialized i set date and time. long getUnixTimestamp() { struct tm timeinfo; //Setup a tm structure based on the RTC timeinfo.tm_wday = dateStruct.WeekDay; t...
Posted on May 01, 2015 at 08:45 Hello, I have not been able to successfully use the newSTM32F1xx HAL I2C on a STM32F103CB. The issue remains the same regardless of the method used (polling, Interrupt, or DMA). When attemptin...
Posted on April 30, 2015 at 21:02I have two almost identical 72MHz boards which have code issues I suspect are related. I have DFU firmware that loads on to both boards, and both appear to the host as a USB DFU device. App firmware is loaded at 0x08...
