Posted on February 12, 2015 at 18:49 I have some brushless simonk ESC`s driving my brushless motors. I noticed that these esc`s are woring on a 1 to 2 ms pulse from a 50hz signal. Wich in duty cycle terms means that i must work with duty...
Posted on January 28, 2015 at 11:26I'm trying to run Boundary Scan on a board with a STM32L100RB mcu. It is the only Component in the boundary scan chain, but I can't get it to work. I get nothing at the JTDO pin. Anyone have any idea what might be ...
Posted on February 19, 2015 at 16:24Hi all,Is there a Linker file where to define flash sections to split my flash Memory code??
Posted on February 18, 2015 at 10:34Hi all,I would like to check my whole flash memory integrity. I´ve the posibility of read the whole sectors and calculate a CRC and check if it is correct by firmware. My question is the following one. Is there an...
Posted on February 18, 2015 at 16:49 We are currently working on using the three ADCs on the STM32F407 to simultaneously sample three analog waveforms. Our target waveform is at about ~30Khz, but to illustrate our problem I have slowed the input...
