• close buffer FIFO Rx uart

    i use ble_uart example nrf51 in sdk1 with ic kline interface with mortorbike NRF51 Tx,RX connect to TX,RX MC33290 and Kline of MC32290 connect to motorbike ( you can Google MC33290) specially,byte that NRF transmit in Tx,will be stored in RX. example…

  • disable uart RX FIFO

    i have project with nRf51822 and uart. i use uart fifo in Uart_app_ble example sdk11. now i need disable or enable Rx, TX.i tried this function : NRF_UART0->TASKS_STARTRX = 1; NRF_UART0->TASKS_STARTTX = 1; and NRF_UART0->TASKS_STOPRX = 1; NRF_UART0…

  • How to read fifo data in TWI?

    Hello. I use nRF52 & mpu9250. I want to use dmp. But now it's not going well. Now, there is no error,but fifo_count doesn't change after fifo_count became 512. I think fifo_count should reset after finished reading fifo data. DMP is enable.…

  • nRF52 app_uart_fifo stops working after an overflow

    I am trying to use UART with interrupts and fifo, by using nRF52 SDK 12.2.0 example. It works until the first overflow, after which I cannot any more receive characacters. The related code from SDK is: case NRF_DRV_UART_EVT_RX_DONE: // Write received…

  • APP_UART_FIFO_INIT crashes

    I am trying to set up fifo'ed uart. However, APP_UART_FIFO_INIT crashes with an error value 8. I traked back the reason into this nrf driver code fragment: ret_code_t nrf_drv_uart_init(const nrf_drv_uart_t * p_instance, nrf_drv_uart_config_t const…

  • UART receive in background without callback on nRF52 SDK11

    Hi, I'm looking for an easy way to use the UART in blocking mode (or something similiar) with a receive buffer that is filled in background: If possible using EasyDMA for better performance and easier software design TX data may either block…

  • NRF52 clear UART FIFO

    Hi, I am using nrf52-DK (First Version in the moment) and need to test UART interface. I use the example from the blue-nus example from the SDK which is working fine. I have only some problems by correct usage of FIFO buffer which is overflowing all…

  • Best way to parse a UART string with FIFO?

    I've got my UART (with fifo) functioning, and now I need to read in a string and determine whether to act upon it or not. I'm using the s110 softdevice, and I found a BLE/UART example where the UART read into a buffer seems to be done in the main for…

  • Advantage of memory pool?

    Hi. I'm currently trying to buffer data from beacon interrupt. So, I choose to use circular buffer. Before implementing it myself, I could find that there's already implemented circular queue in SDK library. But, there're two form of library…
