Hi：
I have the following hardware structure：
FPGA < -- SPI -- > NRF5340 (TX) -- ! (ESB) ! -- NRF5340 (RX) < -- USB -- > PC
Due to the nature of my application, I need to send a lot of data through the ESB with high frequency. (250 bytes of data are transferred every 2ms.)
As a result, I've achieved what I needed. But the transfer was erratic, even when I put the two DK boards close together:
--> I control IO level flipping at SPI receive, ESB send, and ESB receive, respectively.
--> The results show that the ESB receives no more than 30s. And I need to reset PTX to have a high probability to work again.
Here is my project with the code configuration:
PTX and PRX:
CONFIG_ESB_NEVER_DISABLE_TX=y
CONFIG_ESB_TX_FIFO_SIZE=64
CONFIG_ESB_RX_FIFO_SIZE=64
ret..delay = 150, ret...count = 1, tx_mode = manual_start, fast_ramp_up = true, auto_ack = true, crc = off
PTX:
spis_handler:
write_payload, toggle pin 1, set spis buffer
main:
start_tx, toggle pin 2
PRX:
esb_handler:
read_payload, toggle pin 3
The core code is as above, omitting some other code, but I don't think it will affect the solution of the problem, of course, if you need to provide other content or source code is ok.
For the transfer of data, I allow a small amount of data packet loss.
Thanks !
