Resolved! Steval -SPIN3201
Can I connect oscillograph to Steval -SPIN3201 for measurement currents of the phase? Where is this point on board?
[stpm34] I get power factor greater than 1 in my power factor calc
In our system using stpm34, stpm34's registers are read every 5 seconds.Of course, during those five seconds the load can change.To calculate the power factor using the stpm34 register values I read, I calculate the "Active Power (ph1_reg5)" / "Ap...
STPM3x getting default register values via SPI
STPM3x chips are used for developing a multi-phase power-metering application. Boards used: EVALSTPM3x-PH, Nucleo-F302R8, I have ensured the correct initialization of SPI and chip reset at startup ( SCS low, 3 SYN pulses and 1 SCS pulse). Been sendin...

STC3117 Fuel-Guage: (STC3117IJT): Issue regarding the SoC readings at the time of discharging
Hi team,We are working on a platform based on Qualcomm APQ8016E (Snapdragon 410c) . It is a battery operated device and we are using STC3117IJT in our product. We are facing an issue regarding Incorrect battery capacity indication at the time of disc...
Resolved! Help to identify this smd?
Hello =) Do you recognise this component?It's being used in this case between the +ve output of a bridge rectifier and ground I've searched ST & elsewhere and would appreciate your help to identify this & suggest alternatives to replace it. Many...
The BSTOUT pin of STPMIC1APQR already has a 5.2V voltage output, and the SWIN pin is directly connected to the BSTOUT pin, but SWOUT has no voltage output. what error will cause this problem?
First briefly introduce our motherboard. STM32MPU151AAC3 (361-pin TFBGA package) is used in our motherboard, and STPMIC1APQR is used in the power supply. At present, booting from Micro-SD card is normal, DDR3L and e.MMC are working normally. Issue : ...
