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 11, 2016 at 23:34I have project generated by STM32CubeMX 4.14.0 and STM32CubeF7 1.3.1. I use the FATFS and SDIO with DMA. If I wrote a file with higher clock for sd card, then there is an error in the function FR_DISK_ERR f_write. I f...
Posted on January 24, 2017 at 07:58Hi,We configure the timer 1 to run a PWM signal on PA8 & PA9.It works well with the debugger, but when we power the MCU directly, the PWM is not running ! (We can confirm that the main is running... with a manual G...
Posted on January 23, 2017 at 23:01The 32F413HDISCOVERY webpage, and also the data brief DocID029964 Rev 1, both say the kit has:USB OTG HS with Micro-AB connectorhowever, the STM32F413 has 'only' an USB OTG FS.Also, on the picture of the DISCO's P...
Posted on January 23, 2017 at 23:11In synchronous mode, USART_CR2.LBCL allows to omit the clock pulse associated with last data bit.Why?The text in 'USART synchronous mode' chapter hints thatDepending on the state of the LBCL bit in the USART_CR2 re...
Posted on January 08, 2017 at 21:24Hello all,I'm currently working on a bridge that takes in artnet packets (theatrical lighting control) and spits it out as data for ws8212 leds.I've got working code setup and running on an olimex stm32-E407 dev bo...
Posted on January 13, 2017 at 00:15I've run out of DMA channels so I can't run SPI2 with DMA both ways. Since I'm talking to an external NOR flash chip where reading data is of much higher priority than writing I'd be happy with RX only DMA.Setting ...

Posted on January 23, 2017 at 14:57Hello,i want a baud rate of 5 mbps on UART1/UART6 on STM32F207 Nucleo Board (As per reference Manual UART1 & UART6 can have baud rate up to 7.5 Mbps). However when i am configuring in STM Cube MX i am getting baud ...
Posted on January 05, 2017 at 13:59Hello,I use a TUSB2046BVF to connect a host (tablet) to 2 USB connectors and 2 micros, one is STM32F103 and the otherSTM32F107, and I can only operate the 103 when I remove the pull-up resistor at 107.The other por...
Posted on January 22, 2017 at 22:58 Hi! I am using STM32F407 board. I have configured timer 4 for PWM with following code and connected LED to the configured pin. It is working as expected. I used following code: TIM_TimeBaseInitTypeDef T...
