Hi, I am trying to enable data transfer from LPUART FIFO buffers to a RAM buffer using EDMA. My ideal case is to achieve this with out interrupting
If LPUART ISR is enabled with default FIFO and AUTOSAR then max 10kbps communication is possible otherwise Rx buffer overrun happens due to AUTOSAR overhead. I assume enabling FIFO buffer depth this issue will be solved and higher data tares would be possible. I am wondering how I can ...
if (kStatus_LPUART_RxIdle == status) { printf("LPUART USER CALLBACK -- RX IDLE \n"); xbee_uart_rxOnGoing = false; } if (kStatus_LPUART_RxHardwareOverrun == status) { } } My TX and RX Functions void XBEE_UART_WRITE(uint8_t *data, uint32_t length) { printf("LPUART SEND BEG...
Solved: I'm using S32K148-EVB (nxp.s32k148evb-q176). I am testing the example to use uart, but the rx signal from lpuart1 is strange. * Connection:
If RXWATER is greater than zero (say, N), then my LPUART ISR will not trigger until N+1 characters have been received. Per the manual, I had set RXWATER to 1; this manifested as a bug of the FIFO always retaining the last character received, and only delivering prior characters to ...
Hello, I have some questions about LPUART1 of 'S32K142'.I use it with LIN transceiver 'ATA663211'. I use it to be master. My transmit function
Hello , Based on our discussion in a support ticket, the last problem with LPUART_LIN_IP_STATUS_TX_BUSY after SYNC has been send can be caused by an
LPUART1 echoes RX signal at 115200 bps When an 's' char is received, the MCU enters VLPS. A falling edge of the RX signal brings the MCU from VLPS via LPUART RXEDGIF interrupt. BUS_CLK can be monitored at CLKOUT PTD14. In VLPS, BUS_CLK is gated off. ...
Solved: iMX93(9332 soc), pinmux the gpio_io04 & gpio_io05 as LPUART6_TX & LPUART6_RX. dts: &lpuart6 { pinctrl-names = "default"; pinctrl-0
I tried to use S23K312 for Ip Lin debugging with Baby Lin II. Whether I use slave mode or master mode, I get LPUART_LIN_IP_RX_OVERRUN_ERROR, and even LPUART_LIN_IP_FRAME_ERROR and LPUART_LIN_IP_PID_ERROR. I also tried to change the bit rate, such as 19200 or 9600, but nothi...
