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 15, 2014 at 13:44 I'm using USART with circular buffers and interrupts to transmit and receive. To transmit, a byte is written to the buffer, the TXE interrupt is enabled and then the byte is sent and theTXE Flag is cleared in t...
Posted on May 18, 2014 at 11:23hello everybody, i've a problem with cascading 3 timers i want to set TIM1 as a master, TIM2 as a slave (gated) and TIM3 as a slave of TIM1. even if i use hal library i think the problem in my cade is simple! i wrote t...
Posted on May 17, 2014 at 00:52 Hi, I am trying to get the duration of a signal with input capture of timer. I have two signals, which are comming from another chip, CLK and OUT. CLK is 125 KHz and OUT is variable between ~3.5KHz and 4KHz....
Posted on May 16, 2014 at 16:02hello, during the calibration process I saw we must activate the internal regulator, but sometimes I saw a calibration process without this line, so for me it's not very clear, what is the best way? actually I don't ca...
Posted on April 23, 2014 at 19:00Using Win XP. I've installed the latest firmware in my Nucleo board (LINK007). I've installed the drivers on my PC (LINK009). All is well with the USB Mass Storage but the VCP has a yellow '?' in the device manager w...
Posted on May 16, 2014 at 17:55I am having issues with SPI1 and SPI2 on the STM32F373CCT6 chip. 1) I have both busses configured the same as full duplex, 16 bit data, master mode, baud rate scaler of 8. However, when I look at the SPI clocks on a s...

Posted on May 15, 2014 at 16:12 Hi, So I've ran the FMC_SDRAM_DataMemory example, which should allow use of the external SDRAM. However the following, gives me incorrect results: uint32_t aTable[1024]; /* Counter index */ uint3...
Posted on May 15, 2014 at 18:09Hi I just can't understand this... So, I'm communicating with PC's terminal program via USART2 on my STM32F10. Communication is running smoothly both ways, but I have a problem when I want my embedded system to respond...
Posted on May 15, 2014 at 19:35I am currently building a big project on STM32F4 Discovery board for my graduation project. I have configured 4 Timers' interrupts (10Hz, 50Hz, 100Hz and 1kHz), USART communication with interrupt, and CAN communication...
