Dear,   I work on CAN bus with STM32F107 MCU. I arrived to configured CAN 1 with the help of "CAN Networking" example to send and receive CAN frame but when I try to use the CAN 2 (Slave CAN)? I only can send CAN frame. I can't receive CAN frame. So my CAN is correctly configured because I can send CAN frame. I think the problem is with the… (Show more)

I want to add crc function for the IAP-APP function. So I used the CRC example in STM32Cube_FW_F0_V1.9.0 to test. But uwCRCValue is always 0.  I think the uwExpectedCRCValue should be the last four byte (0x0803FFFB-0x0803FFFF), and uwCRCValue should be the same value. Attach is the IAR configuration for CRC. Did my understanding wrong or my code… (Show more)

Hi,   Trying to get I2C communication between a F334 and a 24C32 EEPROM working, The read and write functions do return correctly, but the reads do not match what has been written to the EEPROM. Struggling to find the issue at hand and in the thought that someone could possibly lend me a hand on this issue, which would be very helpful. The… (Show more)

I'm running Mac OSX 10.9.5   I installed STM32CubeMX.app without problem and it runs fine.   However, when trying to install STM32CubeProgrammer.app it hangs at step 6 of the install program. Running the installer from the command line showed that the installer encountered this error: Exception in thread "IzPack - Unpacker thread"… (Show more)

I am trying to interface SPI3 of STM32F4with external SPI F-RAm memory chip. But after writing dummy data(0x00) in data register, data register is set to 0xff and it doest not change and my TXE bit is always set. Have i not initialize my GPIO port and SPI properly? Her is my initialization int main(void) { uint8_t flagstatus=255; uint8_t… (Show more)

Hello everybody!   I want to make a simple VoIP client handling SIP and RTP protocols. It needs to be very simple (connect to the VoIP server, make a call, pick up a call, end call), fast and reliable.  I'm wondering if there are some solutions that could help me to make this? (Simple example would be great ) My first idea was to make own poject… (Show more)

I am currently building a project with a STM32F103RCT6 (shouldn't matter) and I ran into a problem. CubeMX does initialize the SWD-Pins for programming. The problem seems to occur when I enable a timer peripheral on the same Port (PA8 in my case).  My workaround atm is to include a second call to "__HAL_AFIO_REMAP_SWJ_NOJTAG();"  in the " /*… (Show more)

I am new to STM32 controllers and I wanted to create a sample code for counter in TIM1. I am facing a problem that the update interrupt flag, which is supposed to go high when counter equals ARR register, is going high as soon as counter is enabled. I am using discovery F0 board and giving a simplified version of my code   void main(void) {   … (Show more)

Hi, I was doing IAP&App in STM32F030rc.  When I finish IAP and APP, and run from IAP to jump to APP, it can not be realized. I have try many ways, but useless. Please help me, I have waste a lot of time for this function.   IAP project: #define APPADDRESS 0x08020000; typedef void (*pFunction)(void);     pFunction Jump_To_Application; uint32_t… (Show more)
