Composite Devices Support

Hi there,i wondered if it's possible to support more than two composite device classes. I am using stm32f407ig and in the reference it says there is a control endpoint 0 and it supports 3 IN/OUT Endpoints. So it must be possible to implement CDC+HID+...

shutdown mode concept question

I read that when entering shutdown and waking up through a wakeup pin, the program restarts. If I enter the shutdown in my main method, doesn't that mean that when my MCU wakeup it will restart and then enter the shutdown again in my main method?

I2C Busy flag after I2C Clock enable, how to solve?

Hi,RCC->APB1ENR |= RCC_APB1ENR_I2C2EN;immeditly after turning on the I2C2 Clock I get a busy flag for I2C2.Its then reset with:GPIOF->MODER |= GPIO_MODER_MODER0_1 | GPIO_MODER_MODER1_1;But when PUPDR is executed, the flag is busy again:GPIOF->PUPDR &...

Regarding HARD FAULT traps. Does the STM32 (or cortex cpus in general) have any kind of memory region that is read-only, and does not issue a hard fault when written to ?

The intend is to detect whether an array (size 256 bytes) is present in RAM at a location pointed to, and does not trap a HARDFAULT when the pointer written to it. A subsequent read from the same location should produce a value different from the val...

what is the best protocol to send arrays I2C, SPI ?

I have array[2000];I am trying to send from nucleo to arduino, it seems if I send bigger than 8 elements it freezes or does nothing. So I have no problem to send array of 8 elements.I know that I could do it piece by piece in a for loop, I would have...

We use STM32F072RBT and STM3232F373CCT for two designs and the designs are ready for the market. We need a USB VID and PID for the products. How can we sub-license a PID from ST? Chris
