Hello Guys,
I get this warning Type pointer targets in passing argument 3 of 'xTaskNotifyWait' differ in signedness [-Wpointer-sign] when I use the below snippet of code. This happens when you are using an integer value in place of a character. The prototype for xTaskNotifyWait() is BaseType_t...
I have already enabled the clock for GPIOA in my code (See my code above). There was a mistake in my code, I corrected it now onboard LED PIN PA5 turn on but other two pins PA2 and PA3 are off.
My new code:
#include "stm32f4xx.h" // Device header
#define RED...
Hi, Thanks for the replay
I am using Nucleo F446RE Board. There is no external oscillator on the board. I am trying to clock my Nucleo board with internal RC Oscillator and by default, it is clocked at 16MHz. The stm32 chips by default should work at 16Mhz without any clock configuration...right??
Hello Guys,
I am new to arm development. I have written the below code for my STM32F446RE Nucleo board. All I am trying to do is turn on Pin PA3, Pin PA2 and onboard LED Pin PA5. The code compiled and flashed successfully. But no success in turning on those pins even after several retries. Am I...
I think the systemview needs jlink for its proper working. But I can't install jlink because of stm32ide's udev rules. A conflict between jlink and stm32ide udev rules. I tried to delete 99-jlink.rules from the /etc/udev/rules.d but still I am unable to install jlink. How can I permanently...
I have installed seggar systemview in my ubuntu 18.04. But when I try to run sytemview in my terminal, it gives an error
Could not open J-Link shared library. Exiting now.
I followed the below link to solve the issue but I am unable to find /lib64/libudev.so.1 in my pc. I have also tried to...
I have tried different baud rate, but I don't see any change. Also, I have noticed something weird in my serial monitor. It's not responding in ASCII Mode but responding in HEX Mode in my serial monitor.
In Hex View:
After some debugging, I found that when the function...
By not responding I mean it's not giving me on the serial monitor. I am using a stm32f446re nucleo board. In this board, the stlink provides an 8 MHz signal which I am trying to use in bypass mode. I am trying to print a text on the serial monitor in bypass mode.
My HCLK is 4Mhz & baud rate I...
Hello Guys,
I am trying to setup UART under oscillator bypass mode in STM32f446RE Nucleo Board. I have created a new project in CubeIDE with UART under Asynchronous mode. I have commented out the SystemClock_Config and written my code for oscillator bypass mode even though everything can be...
Hi guys, I´m new to Switching Power Supplies. I was reading the EPR32.pdf and I find a device to assembly. This project has an output of -24v/50mA. How I can swap the voltage to positive and improve the current Iout to 1A?
Thank you for the response guys. I am trying to build the schematic just only with PTH components. A Buck circuit I will need some SMT components which I cant buy at this point of time.
Hi, KlausST. I just want to learn. Thats why i choose the hard way. I know its tough but lets see.
Thanks so much for the response guys, I inverted the phototransistor and swap the transformer as mentioned. But I don´t know, how a I dimensioning the flyback return, because now I have 3...
Hello Guys, l Iike to design a AC to DC Isolated Switching Power Supply with multiples outputs with 3v3, 5v, 24v with 300mA each with optocoupler. I using a starter schematic attached below, but I don´t know how I can rewire it for multiple output with 3v3, 5v, 24v with 300mA. Need some help guys!!
Hey Guys,
I am new to edaboard and ARM microcontroller. I happened to encounter the following two macro definition in HAL library in STMCubeMX.
First:
#define __HAL_DMA_GET_TC_FLAG_INDEX(__HANDLE__) \
(((uint32_t)((__HANDLE__)->Instance) == ((uint32_t)DMA1_Channel1))? DMA_FLAG_TC1 :\...
