I can program my bespoke board using a repurposed USB port. It would normally be used by a mouse.I was under the impression that if I powered up the board with BOOT0 pin held high the MCU would be in a state to connect to USB and do it's enumeration....

As per subject. I can see the tasks but it would be most useful if I can see queue status as a USB task isn't always responsive, and mouse movements are discarded if the queue is full.I have added the 12 or so queues into the registry with the vQueue...

I have a FreeRTOS queue with many calls from various tasks.I would like to assign elements of a variable that is passed into the queue with the file name and line number of the task that is placing the variable on the queue.I have a corruption issue ...

I am struggling to find working examples to work with FreeRTOS in an interrupt mode.I use the function HAL_I2C_Slave_Transmit_IT() This enables the interrupt as well as setting up the data.It works to a point, then the remote Master send a Nak and 8 ...

My understanding of a non-blocking function is that the function will return immediately, and it is up to you to use a callback or other method to collect the data. With FreeRTOS it's not difficult.Yet HAL_FMPI2C_Mem_Read_IT() seems to hang around an...

I find this using this bootloader process unreliable.I can put a frequency meter on the 8MHz crystal. Whether it bursts into oscillation is hit and miss. With the application running, ie BOOT0 low, it always starts up.If I hold the BOOT0 pin high wit...

Thanks for confirming. I can't find any programming guide or application note that says that, hence the question.Furthermore, I find for reliable connection I have to power up in reset, remove the reset link and then attach the USB cable to the socke...

Can anyone make any suggestions where else I can ask this question for a solution?

Many thanks.I’m using STM32CubeIDE version 1.15.1And using STM32CubeMx version 6.11.1Libraries STM32Cubde FW_4 V1.28.0FreeRTOS Version 10.3.1CMIS-RTOS version 2.00To my knowledge all version are up to date BICBWThe Task window works well, and I even ...

Many thanks for the quick reply.My previous google searched had failed me. I hadn't search with gnu or gcc.I thought they must exist as they do for the IAR compiler.

Assign a variable to the c-file line number.

Slave I2C interrupt issues

HAL_FMPI2C_Mem_Read_IT() in library "stm32f4xx_hal_fmpi2c.c" claims to be "Read an amount of data in non-blocking mode with Interrupt", yet behaves as a blocking call. Where am I going wrong?
