How to get the energy value from STPM32
Hello,I am using STPM32 as my power sensing IC. In this I am accessing the register 54 to get the energy value. when I access the register 54 it gives me a hex value of 0x52F8FFFF. I dont know how to interpellate this to get the energy value. Please ...
L6564 used to BUCK controller, the buck output voltage is not set-point voltage at startup, and L6564 control logic is incorrect
L6564 used to BUCK controller, the buck output voltage is not set-point voltage at startup, it's output is equal to input as duty cycle =1, please help to resolve it, thanks.the below is waveform and buck circuit, CH1 is output voltage B+, CH3 is buc...
What is the minimum time required for PB about SRC0CS25D at Power-UP?
What is the minimum time required for PB about SRC0CS25D at Power-UP?When PB is pulled to Low, even though PSHOLD is High, the EN may fall Low.PB Low time was about 200ms. The time PB Low to PSHOLD High was about 150ms.If the PB Low time was about 4...
why is l4981A operating current into vcc pin 19 high er than normal
at times the current rises to 300ma and overloads the aux supply , shutting the IC down . What can cause an unwarranted rise in input Q current ?
Why is heating up L6230 chip (on IHM07M1 expansion board)
I have a Nucleo-F302R8 board with X-Nucleo-IHM07M1 motor driver.When I run the motor (using my sensorless algorithm, PWM frequency is 20kHz) the L6230 chip is started to heat up and the temperature of the chip has very fast increased.In the L6230 dat...
the F302 project example of X-CUBE-SPN8 doesn't work
Dear I try to flash the example image which is located at the following path"STM32CubeExpansion_SPN8_V1.0.1\Projects\Multi\Examples\MotorControl\Src"to development board and using six-step to start motorbut the motor doesn't startup , check the failu...
STEVAL-ESC001V1 UART and JTAG Hardware Requirements
For this EVAL board, I see that there are 2 headers, one for JTAG [SWD] and one for Serial [UART] communications. It appears that these are just the raw digital 3.3 V logical connections from the MPU itself.However, there is not a single example sch...
