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 June 17, 2013 at 17:43I'm currently working with a STM32F3-Discovery board which has the STM32F303VC microcontroller on it. I'm planning on eventually using the STM32F373C8 on my board, but I want to test out some code and get comfortable...
Posted on June 17, 2013 at 12:32I am using STM32F205 with 120Mhz interanl PLL(HSI).I have to interface SD Card on SPI with <= 24Mhz. Problem is with 120Mhz sysclk I can only obtain SPI-30Mhz(can't use of SD), 15Mhz(too slow)and other lower freq.Now ...
Posted on June 15, 2013 at 13:38Hi, In our system, our main code loop repeats every 12 seconds and refreshs the watchdog counter. When refreshing the counter, I toggle an LED. The only problem is the blink period. I would lke the watchdog running LE...
Posted on June 15, 2013 at 03:44I'm looking for confirmation (first hand knowledge, please -- speculation is usless) that PA3 on the F37x and F38x are in fact at pin 18 and not on pin 17 as it is for all the other LQDP64-packaged F1xx, F2xx, F3xx, a...
Posted on October 05, 2012 at 09:45Hello, for STM32F1xx a self-test library is available as described in AN3307. Is a similar library available for STM32F2xx? Or can the same library be adapted for STM32F2xx? Bodo
Posted on June 17, 2013 at 00:39I am trying to use the I2C to read and write to an external 24LC024 EEPROM. I am using a polling method since my DMAs are being used for USART2. I remapped I2C1 to PB8/PB9. When I read the EEPROM it works fine and...
Posted on June 17, 2013 at 11:01I have used following code to get CLKout on PC9 but it didn't work:Sysyteminit() was called earlier. /*Enable or disable the AHB1 peripheral clock */ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE); /*Configu...
Posted on June 16, 2013 at 12:38I'm using IAR. My board wold not get programated. In fact the program annonce that the program was successfully downloaded and the debug mode is opned but the program in the stm32 wold not change :\ when I chek the de...
Posted on June 16, 2013 at 06:32Hey guys,I would be very grateful if someone help me for the following issue.I want to compile and save some information in an indoor internal SRAMmicrocontroller when power supply of microcontroller goes offline,thos...
Posted on June 15, 2013 at 08:00HI, I'm starting to implement my own bootloader for STM32F2xx. Currently I plan to support UART, USB and ETH. Also I plan to use EEPROM emulation. Implementation of USB and ETH (TCPIP Socket) takes about 30K. So To b...
