Posted on January 02, 2015 at 15:56I'd like to present real-time kernel: https://bitbucket.org/dfrank/tneokernel. TNeo was born as a thorough review and re-implementation of http://tnkernel.com. The new kernel has well-formed code, inherited bugs ar...
RC PWM output 8ch
Posted on March 16, 2015 at 13:53hi,i'm trying to generate 8 pwm signals with different phase shift and different and independent pulse width.As far as i understood the toggle mode won't let you change the pulse of each signal independetly. I've bee...

Posted on March 14, 2015 at 20:36Hi,I'm trying to implement a GOCR algorithm to 32F429IDISCOVERY board. The GOCR itself works very well on PC but on the discovery board I'm still having some issues that makes it unstable and unusable. Sometimes the ...
Is there a good way to implement a UART driver that uses DMA and freeRTOS?
Posted on March 07, 2015 at 00:35Is there a good way to implement a UART driver that uses DMA and freeRTOS? Or should I let the RXE TXNE interrupts handle the queueing and use no DMA?It would be nice to use tha DMA to shuffle data to an array and th...
STM32 PWM width different pulse width and modified in another interrupt
Posted on March 16, 2015 at 15:53Hi, I need to modify a PWM inside an interrupt, I though that It would be easy, just changing CCR2 to the new desired value but it is not working properly.The change is not happening each pulse, it is a bit random.. ...
