Hi,I'm trying to transmit/receive data by uart. I have a state machine that is processing incoming bytes periodically, so I use a ringbuffer and write every received byte into this buffer.void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ if (...
I want to measure a moving average of the amplitude of a fix frequency, fixed dutycyle PWM signal with slowly varying amplitude but in a noisy environment (DC motors).I want to use as little as possible CPU power to do this and have the ADC do this f...
Hello to everyone. I am currently developing a project using STM32F750N8 and W25Q128. As you can guess, the project has an LCD. So the project is too big to fit into the internal memory. That's why I need an external memory integrated programming. I ...
Hi everyone, first of all, sorry for my english, and I don't know if i should post this here, so i'm sorry if not.I have a problem when i connect the B-L475E-IOT01A board to the pc. It shows me a error message: "error, not recogniced device connected...
Hello,I am currently working with a STM32L4R9-Discovery board with STemWin using demonstration project.I want to use the external PSRAM as a memory for the LCD GFXMMU framebufferfrom LCDConf.c :#if defined ( __ICCARM__ ) #pragma location="FrameBuffer...
Hi everyone,SystemClock_Config() works on Nucleo-144 board but not on Discovery even though they both have a F746 mcu on them.
Hi, we are using STM32f030 micro controller for our tracking device design. We have programmed some boards successfully using STM32 debugger. But in one board we are unable to program the code. there are some data saving to the controller memory whil...
I'm trying to write blocks of ADC Conversions using DMA from the STM32F46 Dsicovery board and I'm having issues writing to the SD card when HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) is called. I'm running a 500KHz timer to trigger my ADC and ...
Hello sir, i am trying to send command to fuel gauge from stm32l476 to get data like voltage,current and temperature of battery but not getting sir.Even sda or scl line unable to see on oscilloscope. i written a code for i2c but not working .please ...
