Hello to everyone,Thank's to the people who will take time to read my problem.To be short, I'm working on a system which embed a STM32F205 MCU. This system can communicate with other similar systems by exchanging UART messages over an RS485 physical ...
Hi, I am working with STM32H747-Disco and I am currently working with I2C bus. My I2C bus is working perfectly fine and I can see the communication. I just have main.c file and everything is there. I am planning to have different file for the initial...
I would like to develope a program for a custom board that uses an external 8MHz cristal oscillator and a STM32G441RBT6 as a MCU. I configure the HCLK to be 120MHz with the PLL but when I try to do a HAL_Delay or a TIM count it gets stuck not countin...
I use timer gated mode for a HC-SR04 ultrasonic sensor which needs microsecond delay. Is it possible to use the same timer as time base to get microseconds? if (HAL_TIM_Base_Start(&htim3) != HAL_OK) // time base for usDelay() Error_Handler(); if ...
We are considering EVLKST8500GH868-ST8500 Hybrid PLC&RF connectivity development kit for our plc development.It comes with Nucleo-G070RB please let me know development IDE and its toolchain needed for the development and also please mention license c...
STM103VET6 IS A GOOD IC OR NOT. We can only set the pll to 48MHz , AND THE CAN function IS NOT ANY SIGNAL.WE CAN USE THE OTHER IC STM32V103ZET6 TO SET PLL TO 72MHZ AND THE CAN FUNCTION IS OK.SO, WE THINK THAT THE IC IS NOT GOOD , OR REMARKED IC.
Hi guys,I have two characteristics, one for get values from mobile applicationand the second one is to reply as notification to user, to the mobile application.I registered to notification characteristic, to reply the user for any changes.I have two ...
A board with STM32L071CBT6 and another with STM32L476RGT6. The former transmit 18 bytes data {02 6E 9B 3B 41 41 00 00 E7 41 96 83 C9 42 00 03 24 97} to the latter. the latter received {02 6E 9B 3B 41 41 00 00 E7 41 96 83 D9 42 00 03 24 97}, that's t...
HiUsing the STM32F103C8 with STM32CubeIDE and bare metal programming, I am trying to read the internal temperature. While I manage to read the ADC, enter the ADC ISR and do the calculation to get the temperature, the result is unrealistic. The data r...
I am using 46uSec sample rate adc to acquire 6 channels data using adc time to trigger adc with dma transfer, but I would like to do average every 4 samples, and do some other calculation every 30 samples. I use 3 channels in Timer 4 to realize adc t...
