Resolved! Custom Bootloader STM32H750
Hello,I am developing a simple GUI for a custom board based STM32H750 MCU.My requirements are the following:Both application code/data and touchGFX images/fonts are stored in and external QSPI (0x90000000) The entire application must be executed in t...
Connect to MQTT Broker with STM32F746G Discovery
Hi, I'm trying to connect to my MQTT Broker with STM32F7 Discovery kit.Firstly, I used MQTT Client in LwIP stack. When I call this function: mqtt_client_connect()the Error return ERR_RTE, mean Routing Error /** Routing problem. */ ERR_RTE = -4...
Resolved! STM32F4xx and STM32H7xx CUBE HAL SPI BUGS
High Level Problem Description:STM32F4xx: Produced on STM32F427IIHxWhat happens:When SPI as master, full duplex, 8 bit & ~1MHz clock speed and doing longer transmissions (e.g. 10 - 60 bytes) using interrupts the current implementation in Keil::STM32F...
Potential bug in I2C HAL layer (STM32Cube_FW_F4_V1.25.0) in I2C_MemoryTransmit_TXE_BTF() ?
Details:MasterMode: HAL_I2C_MODE_MEMClockspeed 400kb/sSymptoms:In Master-MODE_MEM after memory address has been sent a repeated start should be sent (in I2C_MemoryTransmit_TXE_BTF()) before the switch to read. However if the ISR is handled quickly th...
How to correctly use HAL_UART_Receive_IT when sending&receiving data?
I try to use UART to transmit and receive from the same port (transmit query to device, receive response). I receive 1 byte at time, because of unknown message length.Problem is that I first needed to flush uart RX to clear interrupt status, otherwis...
GUI getting slow once the CDC driver starts the transmission.
Hi,STM32f429The GUI getting slower once the the CDC driver starts the communication. If I go to the next page in the screen , the page loading very slowly. Even I am running the GUI task at high priority still it's happening. Once I remove the CDC s...
Resolved! Order of disabling in `HAL_TIM_IC_Stop_DMA` function
Here is the function body of `HAL_TIM_IC_Stop_DMA`:HAL_StatusTypeDef HAL_TIM_IC_Stop_DMA(TIM_HandleTypeDef *htim, uint32_t Channel) { /* Check the parameters */ assert_param(IS_TIM_CCX_INSTANCE(htim->Instance, Channel)); assert_param(IS_TIM_DMA...
stm32f407 USB CDC FS multi-packet transfer
how to transmit data buffer without splitting? Im using HAL library and it says its allowed to send multi-packet without splitting, but when i try to send data to PC it splitts into max packet size that is 64 byte size
Resolved! Task execution time in freertos
I'm using freertos on stm32f407vg Discovery board. I'm running system at 150MHz. I want to calculate time taken by a task for that below is the code snippet. TickType_t initial_time = 0, end_time = 0,diff = 0; initial_time = xTaskGetTickCount...
