STM32L4R9 DSI with ST7797
Hi,I need some initialization code for STM32L4R9 to drive a DSI display (1.2 rounded) 1 line. I cannot find any reference online on how to drive this kind of display. I also have initialization DSI frame from display manufacturer but I cannot make DS...
STM32F4 how to change pins from USART to GPIO and back to USART again
// Init the GPIO GPIO_InitTypeDef GPIO_InitStruct = {0}; HAL_GPIO_DeInit(GPIOA, GPIO_PIN_2|GPIO_PIN_3); GPIO_InitStruct.Pin = GPIO_PIN_2; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOA, &G...
Resolved! SPI timing
Hello,I am familiarizing myself with the SPI controller on a NUCLEO-F303K8 development board using the CMSIS device headers. I have written a program to send and receive a single byte using polling or interrupts. While functionally it appears correct...
Issue with configuration of PF2_NRST pin of STM32C011J6
Here,PF2_NRST pin (Pin Number - 4) is configured as digital input pin.And PA13 pin (Pin Number- 7) is configured as digital output.When toggling the pin PA13, getting proper voltage level 3.3 volts and 0 volt. While reading low level on the input pin...
Resolved! Is it possible to use USB HUB with STM32F4 using external PHY?
Hi, I found a post by Renesas, about using Azure rtos, where it is possible to use the HUB class for USB Host.Can any problem already known to the internal PHY also occur in the external PHY? Is the external PHY able to be used with USB HUB?Using Hub...
