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... ...
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...
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...
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...
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 ...
Posted on April 15, 2014 at 05:04 Hey all, I'm working on a project where I have to process an audio signal in a few different ways. However, I have never done anything of the sort. I have been reading up into how to implement basics such...
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...

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...
Posted on April 14, 2014 at 22:17Hi all, just a simple question hopefully,In the peripheral example for configuring TIM3 for PWM output, calculations for working out PSC and ARR values are given, comments supposing to explain them.The bit thats conf...
