Posted on June 17, 2016 at 22:37 i bought two different ST motor eval boards connected to the STEVAL-PCC009V2; eval6470PD and eval6474PD. the eval6470PD works fine but i want to use the eval6474PD for technical reasons ( current vs volt control). th...
Posted on June 16, 2016 at 18:11After having solved the main issue with my PCB some weeks ago, I'll open a new thread so as to avoid making a mess now things are different. I'm still working on a sensorless (HFI) IPMSM which should run between 0-90R...
Posted on June 15, 2016 at 17:24Hello again,As an update I got my Development Board working blinking a light. I noticed that increasing the pulse frequency in HIN/LIN causes the Gate pulse width to change. The input is symmetrical to the output unti...
Posted on June 14, 2016 at 22:06Where can I download the eval software for the STBCFG01 eval board? It seams to be hidden very very well. It's why I bought this board... Thanks, Kevin
Posted on July 15, 2015 at 22:01A colleague and I noticed something unusual when we were using an L6474 to drive a stepper motor.When the motor was stationary, we observed pulses on both of the motor phases. This presumably corresponds to the PWM p...
Posted on June 09, 2016 at 21:19Hi everyone.Here there is my easy question.How is it possible to charge the battery at the maximum current (70mA)?Actually my solar panel can provide more power than the SPV1050 can use, however the charging current ...
Posted on June 02, 2016 at 09:30Hello, The 4-wire protocol of the LED7708 chip is not clearely explained in the doc. I cannot get it to work. The STEVAL-ILL035V1 board describes all the electrical parts, schematics, but nothing about protocol and pr...
Posted on June 01, 2016 at 09:04Hello guys,I have been working on stepper controller board using L6482 chip, but with no luck making it to work..Problem: I'm getting over-current fault when I try to drive the motor (motor doesn't make any movement)....
Posted on May 16, 2016 at 15:31Can I get a test firmware for this board somewhere?
Posted on May 25, 2016 at 10:08I am evaluating HVLED001 IC’s demo board (STEVAL-ILL069V1) which I found that such demo board have difficulty to power up if the output is loaded (even as low as 50mA). To operate the board I have to power up the unit ...
