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 October 08, 2014 at 14:48Hello :),I need help to solve the communication between processor C805 and BL module. Devices communicate via UART (serial port -> TX / RX pins) and I need to do a basic setup. Then send it AT commnads BL module. ...
Posted on October 04, 2014 at 01:46I want to have an interrupt that is triggerable by software, but without also having it be hardware triggerable. This is easy if there is a spare pin on the microcontroller to dedicated to being a useless pin. But ...
Posted on October 08, 2014 at 02:07Hi All, I have configured the ADC according to the initialization code below and then try to to a conversion to read the VREFINT voltage so as to calculated AVDD. The initialization appears to work ok and the conv...
Posted on October 08, 2014 at 10:33hello all,I am working on a project where I have to design the PCB. I have designed the PCB similar to the http://www.ti.com/product/CC2541 sensor tag... I have used http://www.ti.com/product/cc2541 soc, temp senso...
Posted on October 02, 2014 at 16:28 Hi, I have a major problem about mySTM32F I'm trying to join usage ofPWR_EnterSTOPMode with USART. I use USART1 and 3 from my microcontroller, it initialiaze properly and I'm able to communicate through it. Me...
Posted on September 28, 2014 at 20:37I've been trying to get my st discovery board to receive data from my computer over the USB. My source is attached. I've been working on this for a long time. The progress is slow. I spent weeks just to figur...
Posted on October 07, 2014 at 13:37Hi list, page 932 of the reference manual gives a formula to calculate USARTDIV. But if I check the first entry in table 133 I get completely different values. With Pclk=8MHz I get 8.10^6/(16*1200)=14.7, while the ...
Posted on September 25, 2014 at 22:36Hi all, After reading the RCC_CSR register to determine the reset source, I want to clear the register so as to be able to resolve future non-por resets. When I follow the instructions in the datasheet, the bits...
Posted on March 30, 2013 at 23:59So I am having an interesting issue with configuring the ADC to work with anything but PortA. I can hook it to any pin on port A, change the ADC channel, and it will work. However, I have tried doing the same on Po...
Posted on September 28, 2014 at 16:18i use the cube to generate ltdc ip code of stm32f429，why i can't get the base graphic function such as LCD_DrawLine ,LCD_DrawCircle etc？must i write the function by myself or copy the functions from ''the stm32f...
