I use STM32F769I-DISC1.My program is based on LwIP_HTTP_Server_Socket_RTOS and QSPI_ExecuteInPlace (and https://github.com/vlcekji2/External-Loaders).Basically, in external FLASH I have a program which handles a TCP server. When using data and instru...
GPIO_InitStruct.Pin = I2C1_SCL_Pin|I2C1_SDA_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_OPENDRAIN; LL_GPIO_Init(GPIOB, &GPIO_InitStruct);Code above ...
I have a third party device that is UART programmable.I need to create a USB to UART bridge with password function (access to the device only after entering the correct password)generated the code using the latest version of STM32CubeMX for Atollic T...
We have an application that's currently using a USB BC1.2 IC to enumerate a charge condition (CDP) between a USB-u sinking host and a sourcing device. We're looking to add an IC between the existing circuit acting as the sourcing device and a USB-C d...
Hi,We are designing the Android accessory and we would like to use STUSB4761 in our application.STUSB4761 can source power and become device by receiving DR_swap from the sinking device.Also we would like to put our accessory to continues in device a...
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...
