Hello friends.I try imeplement freemodbus on my project. And I have a problem with connect. My task is here:/* ------------------------ Defines --------------------------------------- */ #define REG_INPUT_START 1000 #define REG_INPUT_NREGS ...
I am looking at the code here that has the algorithm for producing the device serial number reported when the MCU is in USB DFU mode.https://github.com/libopencm3/libopencm3/blob/master/lib/stm32/desig.cThe document they reference there, https://my.s...
I want to forward all data received at the VCP with USB FS to UART how can i implement this specific in code?I have been searching for long time for this and i have not found any good example of it.Can you please help me?Until now i am doing this lik...
How can i forward data which i received at my COM Port via USB FS to a UART of my Choice?I already send data to UART5 and i measured it with an osci and its workinghar buffer[] = "TEST"; HAL_UART_Transmit(&huart5, buffer, sizeof(buffer), HAL_MAX_DELA...
Hi there.I'm trying to set up my NVIC but I'm not able to understand how they work.I'm using two timers, GPIO and UART. I used the function HAL_NVIC_SetPriority and set the next priorities:TIM 1 -> (Preempt: 0, sub: 0)TIM2 -> (Preempt: 1, sub: 0)UART...
Hello.I'm interfacing my STM32F7 with the following current sensing chip:https://datasheets.maximintegrated.com/en/ds/MAX34408-MAX34409.pdfAnd page 8 describes that I need to send a repeated START command during communication. I cannot find a method ...
Hello, Using CubeMX, I have created USB CDC device for FS and started using the CDC.By modifying CDC_Receive_FS() I am able to receive all data sent form the PC over USB and put the data in my bufferAlso (while the USB cable is connected and PC term...
I followed the instruction based on UM2179 User manual section 6.11 (on pp26) LPUART1 communication, "The LPUART1 interface available on PG7 and PG8 of the STM32 can be connected to the ST-LINK or to the ST morpho connector. Another option to do this...
I am currently trying to use the DFU mode on the STM32F769 Discovery Board. I have shorted a connection to VCC to pull BOOT0 to 3.3V (From Schematic R19). I have wired up PA11, PA12 and ground (Using USB pins) to the arduino connector on the board...
Hi there, I've got a new STM32H743I EVAL board and am trying to run the USB audio HS example provided with stm32cube_fw_h7_v130.The Full-speed example works fine.I'm using the correct USB connector, my PC (Windows 10) recognises the device and says i...
