Hi everyone,I'm using Nucleo H723 board. I have used 8 timers in encoder mode to read the encoders. I have also activated another timer to make an interrupt every 4ms to send the data via Usart.everything work good but when I use sprint code to put t...

Hello everyone,I'm using 4 timers of a stm32 nucleo board to count the increments in encoder mode. 2 timers are 16 bit and 2 others are 32 bit. The increments can be between -1,000,000,000 and +1,000,000,000.With 32 bit timers, there is no problem be...

Hi All, I would like to send int32_t decimal number via USART, but with HAL_Uart_Transmit we can send uint_8. Do you have any idea how I can do that?Thanks.

Hi everyone,I need to monitor the amount of 2 variables in the 2 STm32 Nucleo board.I could do that but I have 2 problems. the sampling of each probe is not regular. Cube monitor makes it for example in the time 1, 3, 4, 8, 10, .. ms. I need to monit...

Hi everyone,I have synchronized the clock of 2 F7 nucleo boards with the same external oscillator. To do that I have activated MCO of a third nucleo board and then I have connected it to the Pin 29 of CN11 of 2 boards.2 Clocks of MCUs:I have used the...

Thanks for your reply.But there is a lot of data (15000 numbers) I think queuing is not possible. And when I use the HAL_UART_Transmit in the While loop it does the send data not every 4ms. It's very important to record the data every 4ms. Doing the ...

Thnaks. I changed it in FLASH.ld to the_Min_Heap_Size = 0x100 ; /* required amount of heap */_Min_Stack_Size = 0x1000 ; /* required amount of stack */but the time is still incorrect. I have also tried 0 and 800 or 100 and 800 but it didn't work.

O.K. Thank you so much. I'm a beginner and didn't know that. So I need to try another way to sent data to PC. How can I find heap size?

Hi again,When I start the acquisition it is waiting for the value and nothing happens. How can I solve this?

Thank you so much. It works for positive values. But I have still a problem with negative values. I can't send them because Hal_Uart_Transmit sends unsigned values.(uint8_t)
