Hi everyone,I developed a custom board out of STM32F070CBT6 MCU. The board is supposed to handle a simple logic of a 5x4 matrix (similar to a 5x4 keypad). The algorithm I've developed also involves the same logic used in a keypad that is, The rows ar...
Both of these firmware were extracted from the STM32H743i-Eval part of the version 1.7.0 HAL library code. The board I am using has no I/O expander so I have eliminated that. The HID host firmware has been modified to support both a keyboard and mous...
Hello,I have met an issue regarding STM32H750 revision change. Originally we used old MCU package v1.5.0 which is not compatible with revision V. It fills wrong value into RCC_HSICFGR register and HSI runs on wrong frequency then. This was fixed in n...
I am keep on reading frequency count using Timer and i need to store this frequency count in the DMA for every second (when interrupt trigger). what are functions write into DMA and read back from DMA when PLC requested. i am new to DMA if any sampl...
My USB device has an input buffer of limited size. If the buffer is full the USB driver should respond with a NAK to any incoming data packets until the buffer has enough space for new data again. How can my application signal this buffer-full condit...
I have tried several online tutorials. I succeed with the implementation of the sample code MSC_RTOS included with STM32CubeIDE installation, but when I try to configure the Disco Board on a CubeIDE-TouchGFX integrated project to interact with a USB ...
Hi,I bought a nucleo L496ZG, and I would like to connect a keyboard to it's micro USB. I read the nucleo manual that I need to enable the PowerPin (PG6), I did it. Now the LD8 should light and the device should get power, but nothing happens.Does any...
We are using stm32h750xb for our project running uC/OS-II RTOS.Question: is there a way to check the remaining heap size for the system at any point of time after the product is up and running.
HI,All , if any one have done HSE enabling in Stm32f072 & Stm32f103 MCU please share.As what ever examples available are for HSI clock only .So please some one revert .WaitingRohit
The PHY chip for HS is USB3320. On the SCH part of UM2198, PIN32 of USB3320 is optional connect to MOSFET. Is it for power on sequence purpose? I can not find the power up sequence requirement for this.Is it requirement of H753's HS OTG?
