Hi.I'm working on a project using I2C on the U545, and I've noticed that all the HAL_I2C_Slave_* functions include the following:/* Enable Address Acknowledge */hi2c->Instance->CR2 &= ~I2C_CR2_NACK;However, the STM32U5 Reference manual states that wr...
Hi I am using STM32F407 and I want to interface SX1262 XXXM LoRaWAN/GNSS HAT into the host MCU.I was porting LoRaMAC stack into stm32f407 using stm32cube ide referring Lora-net/LoRaMac-node: Reference implementation and documentation of a LoRa networ...
I am new to FreeRTOS ( RTOS in general, although I am very familiar with baremetal) and am following along with this video:https://www.youtube.com/watch?v=CdpgqpuPSyQ&t=4s I am using a STM32F3DISCOVERY board so I had to make some minor tweaks to foll...
Hello everyone,I am struggling with a problem that has not been solved before. Perhaps someone could be found who would be able to solve it. The issue is with the operation of the interrupt for receiving a character via USART. The interrupt is not re...
I do have this demo program in which main.c is disabled so it would start from main_pinpong.c which is the only file withint main( void ){included in target build startup_stm32l476xx.s is supposed to be the startup file but I do not see any reference...
Hello, I'm new to STM world, so I'll post what may seem a trivial question to many, but which is not totally clear to me: I'd like to understand better the behavior of the micro controller in a situation like:/* Configure ISR on UART RX */ /* Enter ...
Hi!!I am using ThreadX to develop a project.As far as I know, when using FreeRTOS, it is highly recommended to switch from SysTick to another timer.Is it the same for ThreadX?Therefore, I am using TIM7, which is a simple timer. I was wondering where ...
My USB is a virtual COM port. I am trying to implement the BCD feature in order to detect what type of port is present when USB a cable is attached. We have charging capability and will use the type of the connected port to determine whether to enabl...
I am using LWIP 2.1.2 in stm32f769I discovery board.I can ping IPv4 from my PC.But i can't ping IPv6.I have enabled the Autoconfig(Stateless).As per my understanding the IP address will be created based on the MAC.My MAC is 00:80:e1:00:00:00Link loca...
I'm writing software that involves reading a single ADC value from my STM32H7R3V8H6, however it is getting stuck in HAL_ADC_PollForConversion(&hadc1, HAL_MAX_DELAY);.If i switch the delay to a smaller value it runs through but it still returns a time...
