Transfer in the background example
Closed this issue · 9 comments
I'm using two ESP32 Devkit V1s with the "Transfer in the background example". There are two things I have been having issues with. I am new to using SPI so sorry if these have obvious answers.
The master constantly returns "successfully received expected data from slave" while the slave is stuck on "wait for the completion of the queued transactions..." and never prints the "successfully received expected data from master".
The second point I'm a bit confused about is where the data is being sent, are tx_buff and rf_buff the data being transfered? Where would I read the data to ensure it was verified before use?
I verified the pins as seen below, and changed the PIN_SS = 15 to PIN_SS = 5 however this did not affect the output.
MOSI GPIO Pin: 23
MISO GPIO Pin: 19
SCK GPIO Pin: 18
SS GPIO Pin: 5
Could you give me a serial port output for both master and slave? Also, please enable debug logging mode by setting Arduino IDE > Tools > Core Debug Level > Debug.
The second point I'm a bit confused about is where the data is being sent, are tx_buff and rf_buff the data being transfered? Where would I read the data to ensure it was verified before use?
Yes. tx_buf will be automatically sent, and rx_buf will be automatically updated if the transaction is completed. You can validate the completion of all the transactions by checking hasTransactionsCompletedAndAllResultsReady().
I enabled the debug logging mode and here are the serial outputs:
Master Serial Output:
10:21:20.865 -> successfully received expected data from slave
10:21:22.840 -> successfully received expected data from slave
10:21:24.883 -> successfully received expected data from slave
10:21:26.840 -> successfully received expected data from slave
10:21:28.850 -> successfully received expected data from slave
Slave serial output:
10:20:44.061 -> start spi slave
10:20:44.061 -> initialize tx/rx buffers
10:20:44.061 -> execute transaction in the background
10:20:44.061 -> [ 2061][D][ESP32SPISlave.h:134] spi_slave_task(): [ESP32SPISlave] new transaction request received (size = 1)
10:20:44.061 -> wait for the completion of the queued transactions...
Are you using transfer_in_the_background_slave.ino example, “as is”? Or do you have any changes?
If you use it without any modification, I can't understand what happens from your log. Could you give me an image captured with a logic analyzer or oscilloscope?
Also, could you try other examples, “as is”?
Why the timestamps of your logs are not synced? Please show me the logs synced with master and slave.
Sorry, I don't have a logic analyzer or oscilloscope. I think I will use another communication method however, hopefully this may be useful. Please let me know if you want more information/tests done, thanks.
Here are the synced outputs as close to what I have:
Master (Output as is):
13:27:31.648 -> successfully received expected data from slave
13:27:33.610 -> successfully received expected data from slave
13:27:35.628 -> successfully received expected data from slave
Slave (Output as is):
13:27:35.189 -> start spi slave
13:27:35.189 -> initialize tx/rx buffers
13:27:35.189 -> execute transaction in the background
13:27:35.189 -> [ 2061][D][ESP32SPISlave.h:134] spi_slave_task(): [ESP32SPISlave] new transaction request received (size = 1)
13:27:35.235 -> wait for the completion of the queued transactions...
The only change I made was making PIN_SS = 5 from 15, changing it back to 5 did not have an effect.
An additional weird effect I found was when the single esp32 master was not connected to anything it still outputs successfully received data most of the time:
Master output (No wired connections)
13:32:33.822 -> successfully received expected data from slave
13:32:35.779 -> successfully received expected data from slave
13:32:37.813 -> successfully received expected data from slave
13:32:39.783 -> master [0-26]: 00 01 02 03 04 05 06 07 44 0B 0B 01 88 FF FF FF 40 0C 0C 02 84 FF FF FF 48 0A 0A
13:32:39.831 -> slave [0-26]: FF FF FF FF FF FF FF FF 02 00 00 00 74 DC FB 3F 00 12 13 17 0F 00 00 00 01 10 4C
13:32:39.831 -> unexpected difference found between master/slave data
13:32:41.817 -> successfully received expected data from slave
Additionally, when running many of the examples errors occur during compilation. I've tried reinstalling the Arduino IDE as well as the library but it did not affect the output. This is the "transfer_in_the_background_slave" code which compiles fine on my laptop but not my computer, both are running Arduino IDE 2.3.2

First, please confirm your environment.
- Please use the latest esp32 platform (v2.0.14). Maybe your esp32 platform is outdated.
- Please use the latest ESP32PISlave library (v0.6.0)
- Your connection seems to be unstable. Please refer https://github.com/hideakitai/ESP32SPISlave?tab=readme-ov-file#notes-for-communication-errors
Next, please make sure to start slave first. Then please start the master. Slave wait for the transaction from master, and then master start transaction. The slave receives and responds to the master's transaction.
If you still need help, please feel free to reopen this issue.
