I tried 2 demo printf using HAL and UART Tx using LL from your examples. LL demo runs ok and getting message display on Serial COM console. HAL printf demo got not message display. Any suggestion? I hv another board NUCLEO-F411RE works ok for HAL UAR...
Hi,i'm trying to connect an STM32L072cz mcu ( as a master ) to a gas-module (as a slave) which 7-bit address from data sheet is "1100101b",Wiring, pull-up resistors are placed correctly,i'm trying to test if the communication is well established betw...
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...
