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 25, 2014 at 16:04I'm using F105RBT6. I'm not sure if I'm getting this right but it looks to me that I have to configure PA11, PA12 (I use host mode only so PA9 and PA10 probably isn't needed but correct me if I'm wrong) tp AF mode in o...
Posted on May 27, 2014 at 15:17Hi everybody,I'm programming a STM32F205. I program it with a J-LINK and IAR, and it works well.Now I'm trying to use a ST LINK V2. It seems to program my microcontroller, because I have no error, but I have a warming ...
Posted on May 21, 2014 at 21:43i am using STM32f207i have a flash memory connected to SPI2. I used the ST examples and i got it working, read/write, .. great, ... the problem is the speed ... how fast can i run SPI2? There is a setting SPI_InitStr...
Posted on May 27, 2014 at 19:17Dear all,I have tested the pwm on the STM32F429 EVAL board. It seems all ok.Then I have seen with oscilloscope that with low values of duty cycle from 1% to 20% the pwm works for a while then stops and then restarts.Wi...
Posted on May 25, 2014 at 05:48On the NUCLEO-F401RE, using the STM32F4xx HAL UART driver function HAL_UART_Transmit() to send a sign-on message to the ST-LINK/V2-1 virtual COM port to the host PC, I have noticed the sometimes the full sign-on messag...
Posted on May 27, 2014 at 08:11Hi.I wonder how i can config the STM32L Discovery clock speed from 32 Mhz as it is now down to 25 Mhz. #clock #stm32 #discovery #speed #mhz
Posted on May 26, 2014 at 10:50Hi, I just try to get an STM32F401 running, but it somehow does not seem to work with the standard STM32F4 system-startup files (e. g. from STM32F4 discovery). Is there some comparison PDF about necessary changes when ...
Posted on May 27, 2014 at 13:53I use an STM32F107RC board and use USART2 interface. But USART2 Tx doesn't send first four bytes of each data transaction. I have tried both INTERRUPT and DMA mode.What is the problem? #dma #usart #stm32
Posted on May 27, 2014 at 10:15Is there any example code for implementing DMA on stm32F205rbt6 where I can do rx & tx together.1. I have to send 512 bytes & receive 512 bytes2. After 1 byte tx, wait until one byte received.3. then transmit next byte...
