Hi, erasing a complete page (2KB) to just write a few bytes is a waste of erase/write cycle. Is there a way to write data in differents part of the page each time? when there is no more space then a page erase should be fired and start over. Is there...

Hi, I'm working with a stm32f722 and a ublox f9p gps. I just have 2 ubx messages. One with 36 bytes long and the other with 72 bytes. They income with a variable interval between them (a couple of byte time at most, usually they come together). This ...

Hi, I would like to use cubeide (MX tool) to generate a project that use EXTI_13 but with IRQ disabled by default. I can choose Enable/Disable (generate all code or none), Create code on MSPInit function or in MX_NVIC_Init, call HAL_GPIO_EXTI_IRQHand...

Hi, I have a sensor that send data over uart to a stm32f722 uC. This sensor is powered at the same time of uC. I've noticed that some times the sensor stop sending data. For example, if the code is running ok and then reboot the uC some times the sen...

Hi, I have a problem using stm32f722 uC with HAL 1.16.0 and 1.16.1I write a simple UART send project and test it with an oscilloscope (becouse it doesn't work with the target device) and discover that HAL_UART_Transmit is sending correct bytes while ...

Once the 2 consecutive messages are buffered, there is 200msec to the next couple of messages. So, there is time to process the messages. The problem is how to determine the end of the last message (on this frame) in order to process the them.Let's s...

yes, but the time gap between 2 consecutive messages is variable. Some times they are one next to the other and some times they are several byte time apart. I was trying to use IDLE interrupt to parse each messages as soon as they are on the receive ...

"Poll the buffer periodically to detect new data using the DMA's NDTR register"The periodically part is my problem. I need to parse the messages as soon as possible. While data are incoming there is no free time to parse. So I need to detect the end ...

Thank for your answer. In fact I was adding this code:void HAL_UART_ErrorCallback(UART_HandleTypeDef *huart){ if (huart->Instance == USART1) // ECT-400 UART { HAL_GPIO_WritePin(LED_G_GPIO_Port, LED_G_Pin, GPIO_PIN_RESET); }Just to confirm that ...

Ok, I thought so. Thank for the confirmation.
