I was wondering if i were able to put 3.8V on the E5V power line. I checked in the User Manual and there is standing this at page 21: E5V CN7 pin 6 4.75 V to 5.25 V 500 mAWhen i look at the datasheet of the step down converter (LD39050):https://www.s...
Hello everyone, I am trying to run a program on my board. I could use the same method to debug the program on a different chip but now it is not working on this board. I am using the st-link v2 programmer. but I get this error:***********************...
I all. I am working on a bruhsless motor applicaiton with a STM32F103RCT6 MCU. I got twice the same problem on my board which ended first time by changing the MCU. Before removing a second MCU, I would like to understand the problem. My board has a s...
Hello,is there any library source code available for MT25QL128 external flash interfaced with STM32Thanks
Hi!.I have STM32L431CB , I have interfaced SRAM with SPI to it. I am looking for effective solution for data compression ( like LZ77 ) for the same.Are there any integer data compression libraries ( like LempZiv , Huffman, etc ) available for STM32L4...
I have been trying to program the Op-Amps on STM32G474RE using the latest STM32CUBEG4 version 1.2 and my version of STM32CUBEMX is version 5.6.1. I am trying to get PGA mode to work. In STM32CUBEMX, I selected PGA connected. When I tried to bias one...
i'm trying to send data using SPI. i'm getting started with a simple example with is a loopback test. so when i used the HAL_transmitReceive(..) it worked pretty well but when i tried to use it in interrupt mode the last byte of the array that i'm se...
Hello everyone !I wanted to ask you please what type of document I can see for information on Cortex M3 / M4 / M7 processors, I would like to see the generic versus specific instruction sets, optimized execution, etc.Do you have an idea ?Thank you ve...
I am trying to implement I2C communication with L432KC (bare metal coding) to interface peripherals like port expander, eeprom. But I am having a hard time figuring out the TIMING register. I have several questions:tPRESC = (PRESC+1) x tI2CCLKThis is...
I have two external clocks connected to TIM1 and TIM2 of the stm32f746 (disco). I'm basically trying to implement a frequency counter of the clock connected to TIM2. The TIM1 clock will act as window (driven by a TCXO). In my test setup the TIM2 cloc...
