I can’t seem to get the FIFO to work on the RX side. TX works fine.Seems as if the FIFO isn't used. If I interrupt on the "RX not empty" event and read the data, it works fine. But as soon as I want to interrupt on any FIFO event, I never get the int...
can somebody give me a point to an eval board set that I could use with perhaps STMCube toolset?Thanks so much for your kind help and for the kickstart.
I my project I use UART 1 and 2 and SPI 1 and 2.When I send data via UART 1 using the function "HAL_UART_Transmit_IT (....)" and the second line in code I use the function "HAL_SPI_Transmit (....)" the data received from the UART 1 is incorrect, th...
I am using STM32F103C8T6(Blue Pill) with STM32IDE.> I am trying to learn external Interrupt. So as a reference i am using 3 main thing. # Reference Manual # DataSheat # Cortex™-M3 Devices Generic User Guide> I wrote a code for this. I made changes...
Hi, I'm using an STM32F429 MCU and trying to connect to a sensor through I2C. However, I measured both I2C pins with an oscilloscope and they were not showing any clock pulse or a signal. Here's my code for initiation:void MX_I2C1_Init(void) { hi...
Hi I am trying stm32f429zi discovery board for testing SPI communicationI've successed transmitting and receiving data on ADC chipBut I want know "How do these datas going so well?"So I checked __HAL_SPI_TRANSMIT functionSo I found that hspi->ins...
Hello, I have configured project in CubeMx for above mentioned board using HAL library with 2 UART lines and CAN.CAN line connected to Kvasar CAN dongle via this transciever https://www.ti.com/lit/ds/symlink/tcan1042-q1.pdf. While CAN transmit works ...
The datasheet for the STM32G431 (DS12589 Rev 2) shows that the I2C3 peripheral is available on pins PC8 and PC9, but on page 206 of AN2606 Rev 42 it says that the bootloader is using PC6 and PC7 for I2C3. Since STM32CubeMX 5.5.0 agrees with the data...
Hello everyone,I am working with STM32H755ZI,, ARM GCC and J-Link GDB.Considering Reference Manual the H755ZI has following Memory Map (cutout):...0x40007C00 - 0x40007FFF UART8 0x40007800 - 0x40007BFF UART7 0x40007400 - 0x400077FF DAC10x40006C00 -...
