I do my code with CUBEMX 5.6.0 with en.STM32Cube_FW_F7_V1.16.0 & Atollic 9.2.0.My trouble : when i send a data by USART3 (using putty or the terminal in Atollic) even if i set that i want to recive 1 byte the HAL_UART_RxCpltCallback is fired two time...
Hello,I'm trying to get a SPI communication in between two STM32 running with DMA. One is the STM32F051R8T7 (slave), the other ist the STM32F412ZET7 (master). There is nothing else on this SPI-bus. The best would be, if it runs with hardware controll...
This STM software allows to monitor and modify the value of some variables in real-time using the SWD or JTAG connection in a non-intrusive way.In the documentation for the use of this software (https://www.st.com/resource/en/user_manual/cd00291015.p...
Hi,I am using the STM32F413ZHJ6 in a design, BGA package. I have noticed some strange behaviour in the IBIS model of the part. When modelling the output of K11 and K12 (PD14 & PD15) the capacitance for the model is in the nF range. This is very large...
UPDATE: The issue has been solved. The nBFB2 option bit had to be enabled.Hello, I am currently programming and STM32L152RE on a Nucleo development board. I am using SysTick as a .5s timer that ran a status LED. Everything was working up until recent...
Hi all, I'm using STM32L476 and I am using its BxCAN with a transceiver TJA1042. I have the transceiver's RXD to STM32's CAN_RD1, and TXD to CAN_TX1. Both pins on STM32 are set to be pulled up. And the transceiver does have a 3.3V reference. There's ...
Can you share a sample project that controls the ad9833 module with the stm32f4 board?
Hi, is it possible to connect STM32 instead of display and read its pins (A0, RD, WR, D0, D1, D2, D3, D4, D5, D6, D7) to know what device is sending and maybe replace original display with different display?For example I would need to detect that WR ...
in STMCubeMX it says that CAN1 and CAN3 are master and CAN2 is slave. I need to use all three CANs as slave.Would it be possible to do that? If i can do that would i just be configuring the CAN1 and CAN3 as master in STMCubeMX and continue to use the...
Hi,The documentation between the STM32G4 RM0440 Rev 3 and between the individual MCU specifications is inconsistent when it comes to the PLL limits. In the documentation for RCC_PLLCFGR we have the following two statements:PLLN: "The software has to...
