[STM32F10x] Timer 1 overflow/underflow not correctly
Posted on June 26, 2016 at 07:06Hi everyone,I'm building a BLDC motor control project which use 6 steps for control. And now, i wanna sample ADC on timer1 overflow when PWM-ON (PWM run in PWM mode 1 and Center-Aligned3). I get an issue: Timer 1 over...
L6480 SPI errors versus gate drive configuration
Posted on June 20, 2016 at 08:23Hi, I designed a board equipped with two L6480 motor drivers; the drivers are connected in daisy chain mode. To keep the two motor synchronised, the OSCout of the first driver of the chain feeds the OSCin of the secon...
evalL6474PD not working
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...
Sensorless IPMSM (HFI): Problems with North-South Identification and motor turning in wrong direction
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...
L6491 Dev Board Control
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...
STBCFG01 and the eval board software
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
L6474: Can only see pulses on one of the phases?
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...
Output current SPV1050
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 ...
LED7708 4-wire protocol
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...
L6482H settings.. What I'm doing wrong?
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)....
