Hello,I am using ST USB Device library, STM32f746 controller.I am not facing any issue while sending data to the Controller from the PC host application.But while reading from the device , the device is disconnecting.Can Any one help!Thanks,Upender.
in stm32cubeMX configuration of SPI in slave mode, it asks for user parameter input for clk prescaler, which then derives the clk rate. My understanding for SPI operated in SLAVE mode is that the master end, instead of the slave end, generates the c...
Hi,I followed the AN3990 and managed to update the code supplied to use HAL and get it working correctly on our custom board. But in my readings on custom bootloaders in the forums, it mentions things like disabling interrupts before jumping to ...
