Discuss hardware and software design challenges, including NOR flash storage, OTA updates, component ID, and thermal management.
I plan to design active speaker amps with TDA7269A (single ended), these use zobel R+C at the output for stability reasons as per datasheet. But I was thinking to maybe also include RL output inductor in series to the speaker after zobel as it is oft...
I used the settings and code below for a simple project: Blink an external DIP LED using the blue pill:In Pinout & Configuration:- PA5 => GPIO_Output- user label: LEDThe wire connections (like screenshot below):PA5 pin => Resistor => Long leg (anode)...
hi,I start to use STM mcu to develop power electronic circuit and software , I find the following stuff " STEVAL-DPSTPFC1 3.6 kW PFC totem pole with inrush ......." is the best reference design to me for learning , would you please deliver its sch...
I am using ST3232CTR with stm32f446re . I want to attach LED with either pin 13, 14 or Pin 11 , 12 of ST3232CTR. Like FTDI , if we have serial communication it will blink. But I need recommendation of schematic diagram or how to attach. Can anyone ...
First time working with an STM32 black pill. I have a circuit that connects a Raspberry PI (3b) to the STM32. I am getting errors when attempting to program it using openocd via the SWD lines. I suspect it is a voltage issue, but I don't know how ...
Dear STMicroelectronics Support Team,I hope this message finds you well. I am currently working on a project involving the L6562A Power Factor Correction (PFC) IC and would like to simulate it using TINA-TI.Could you kindly provide the TINA-TI Spice ...
Hello,I built a test circuit similar to one provided in the TDE1747 datasheet (Figure 3). During testing, I observed that immediately after powering on, the power supply voltage appears at both inverting and noninverting terminal of the IC. This beha...
Hello Team,Kindly provide reference material like startup sequence and handling HFDA802 IC.I want to use HFDA802 audio IC with controller but startup sequence and steps are not mentioned in attached datasheet.if possible kindly provide reference samp...
Hi there, For my project, I'm use an M24M01E-F I2C EPPROM. I found Four addresses (0x50, 0x51, 0x58, 0x59) with the below mentioned hardware connection were found when scanning the address for this IC. What changes are necessary to set up the I2C EEP...
I'm using NANO 33 BLE SENSE. Could I ask if the magnetometer in LSM9DS1 uses AMR or Hall technology?
