Hi,
I'm trying to use an STM32F411 Nucleo (Nucleo-F411RE) to drive a few Adafruit Neopixel LEDs (also known by the part number WS2812). These use a digital pseudo-PWM control signal to transfer digital d...

Looks like a bug has crept into the v1.1.1 Standard Peripheral Library -- if it's built with STM32F30X #defined (e.g. by specifying -DSTM32F30X on the gcc command line), the build will fail.
Addition...

Hi,
I'm using the PWM (driven by the DMA controller) to run a line of LEDs. These devices interpret a long high pulse as a start of packet. A pull-down resistor keeps the output in a 'safe' state until the I...
Posted on March 15, 2014 at 09:59To be honest, you really shouldn't be allocating variables as large as that on the stack. The total size of those is going to be several kilobytes! Prefixing them with the ''static'' keyword will move them to the hea...
Posted on March 10, 2014 at 21:19TIM_OutputState determines whether the output is enabled or disabled. It sets or clears the CCxNE timer configuration bit for the respective timer. TIM_OCPolarity determines whether the output is direct-acting or inv...
