Discuss hardware and software design challenges, including NOR flash storage, OTA updates, component ID, and thermal management.
I am working with the M41T83ZMY6F RTC (internal crystal version) in a project and I’ve encountered an unusual behavior: when I read the time via I²C, the RTC seems to count at exactly half the expected rate. For example, after one real second, the se...
I am working on establishing HART communication using an STM32H723ZG Nucleo board, a Maxim DS8500 HART modem, and a 2088 Pressure Transmitter (4–20 mA + HART). Hardware Setup: STM32H723ZG USART3 → Debug to PC (115200, 8N1, no parity) USART6 → Conn...
Background:I recently bought a STM32 blue pill and STLink V2 online. This is my first time using a STM board, I am quite familiar with arduino, esp and 8051(Proteus simulation). Problem:I have attached the 'error.png' file below it is a 'failed to st...
Hi Sirs,Does the TSX3702IST have a POR function?Due to our applicaction face some problem need to clarify this function.Thank you.PaulTseng
As per subject, is the ST LM311DT rail-to-rail? Farnell claims that it is, but that's the only place that says it is, I can't find a definitive statement in the datasheet.(I have used the TI LM311, and that is not rail-to-rail. I need to handle input...
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 ...
