STM32F405 + ADIS16485 IMU, SPI troubles

Posted on April 16, 2014 at 22:37 Hello forum I've just signed up here since I ran into troubles reading sensor data from an Analog Devices IMU with SPI. I'm still a beginner with the Cortex M4, so maybe I'm missing something crucial... ...

SPI maximum SCLK speed

Posted on April 16, 2014 at 10:57I'm currently trying to interface an STM32F4 (discovery) with a telemetry unit (RFM42B if anyones interested) using SPI.The minimum clock time high and time low given in the telemetry devices datasheet for SPI are 40...

Dominant/Recessive state support for UART

Posted on March 25, 2014 at 17:48A wish for new chips: It would be nice if STM could consider to implement a UART which supports bit-wise arbitration, as it is required for KNX / EIB networks. KNX/EIB of course is a big market, but this functionali...

Current Consumption Calculation for STM32L062K8

Posted on April 15, 2014 at 07:47Hi I would like to use STM32L062K8 for our low power application. The peripherals we will be using are 1 I2C, 2 watchdog timers(WDI, WWG I think), 1 SPI, 1 UART(RX, TX), and 3 general purpose timer.Timing for asynchr...

faliing to migrate trivial example from TIM6 to TIM5

Posted on April 15, 2014 at 15:23 I have a snippet which works, it blinks blue LED on stm32f4discovery: void TIM6_DAC_IRQHandler() { if (TIM6->SR) GPIOD->ODR ^= (1 << 15 ); // Toggle D15 TIM6->SR &= ~1; // Interrupt has been handled ...

STM32F439I-EVAL2 board support and configuring STM32CubeMX

Posted on April 15, 2014 at 19:14I just purchased the STM32F439I-EVAL2. The board didn't come with any BSP or code that I can build in IAR. I'm guessing I need to use STM32CubeMX to configure the Bsp and setup the pinouts used on the board. Unfortun...

How to retrieve 8MHz from 168 MHz processor

Posted on April 11, 2014 at 08:21I've got STM32F407VE controller that works at 168 MHz. I need to get a 8 MHz clock frequency from it and I guessed to use a timer in PWM mode, but they all have a 42 MHz or 84 MHz clocks and so I can't use approriate...
