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...
Posted on January 21, 2017 at 18:40Hi,I downloaded stm32cubef1 firmware package. I am using examples on STM3210E_EVAL projects. With the EWARM(IAR embedded workbend for ARM), I see all examples use startup_stm32f103xg.s as start up file.I am using...
Posted on January 21, 2017 at 04:50You want us to use the HAL, ok fine. We use the HAL. But we still often times need to know what hardware we are running on. What is the factory approved method for determining which board/chip is running?Where is ...
