Hello, I am using ISM330DLC sensor for my application on Esp32. Data ready pin from esp32 and sensor is being used to check if values are avalaible on the sensor or not. As per the Application note AN5125, Data ready pin should high for a while and ...
My first ever PCB design. Any comments? Tips or tricks?
Hello stm community. I am designing my first ever PCB board and i need some comments of yours. Here is the screenshots of the pcb schematic and pcb itself. Do you see any mistakes etc? Also I am not sure about the VCAP connection. Is it correctly mad...
Resolved! EEPROM reliability.
Can anyone confirm that a new M24M02 eeprom 256kB is 100% filled with 0xFF when first used?im wondering if we have a major bug where there are already settled parameters in our system because of addresses with something else than default 0xFF. thank ...
Resolved! WDI not triggering NRST properly for SMT818
Hello,I purchased several of the SMT818 chips and was testing its watchdog timer capabilities for my TI MCU. I started with an input pulse that the MCU sent every 500 ms from a 3.3V GPIO pin into the WDI input. Looking at both this input pulse and th...
Problem with noise with addressable LEDs
Hi! I'm using Inolux_IN-PI554FCH LEDs with a custom PCB, controlled by an STM32H563VGT6.When using the LEDs and setting a colour like 255,0,0 (RGB) the noise generated on the data track is negligible. However, when I set a colour that is not 255, the...
STM8S005K6T6 needs working within 10ms
Hello everyone!I have a question and seek your help: I use STM8S005K6T6 microcontroller and cc1101 RF transceiver module, and the operation at 433 MHz is affected. It generates power automatically and can only last for 10ms. The voltage remains at...

Resolved! How STM8S001J3 use BOR function?
Hello. I am using the STM8S001J3 MCU. I want to use the reset function in my MCU. stm8 has a total of 9 Reset functions.●External reset through the NRST pin● Power-on reset (POR) and brown-out reset (BOR): During power-on, the POR keeps the device un...
Outcome of connecting pin 1 (DNU) on M24M01-RMN6P to 3V3
I'm working on a new board supplied with an updated EEPROM (M24M01-RMN6P), when the EEPROM was added to the schematic an old symbol was used where pin1 was E0 not DNU, as such it has been connected to 3V3 (VCC) instead of VSS.The board has now been m...
