Re: Bidirectionality of a XU316-1024-QF60B-C24 pins
How bidirectional busses work? I2C is the simplest pin to have this question. Simple explain is semantic code set port 4E as input all pins is input check somethink on it switch port 4E to output open drain or based on your schematics write out data for SDA ACK on one bit set port 4E back to input ...

Re: xflash problem cant find target XN
You create some mistakes , cant place after upgrade 1 path to file, you learn right syntax
For bin name and folder is simpler use checkbox Output to file etc.

Re: custom XMOS board not working with AN00129
Maybe you skip important point. Between 1 and 2 is required configure xn file in project for your board schematics.

Re: XMOS automatic boot
Simpler RC isnt good for XMOS plus at moment of reset you need valid CLK. Not scoped.
Try quicker RC or better voltage controller reset ICs.

Re: AN00124_CDC_VCOM_class as UART bridge
I go back to most simple while based on references : while (1) { // Wait for a byte to uart select { case uart_rx.data_ready(): { uint8_t data = uart_rx.read(); cdc.put_char(data); } break; default : break; } if (cdc.available_bytes() != 0) { char data_from_cdc = cdc.get_char(); uart_tx.write(data_f...

Re: XUF232-1024-FB374-C40A Not Booting
We have simmilar problem and my result is xburn code is buggy and dont verify otp before lockit = locked is failed OTP. Result is unusable brick.
I create own verify script , that handle burn in more phases write - read - compare - lock or if compare fail write repeat. That help XUF216,208 .

Re: AN00124_CDC_VCOM_class as UART bridge
@Ross now i do loopback and second com loopback testing and handle code to work OK to speed 115200, but rx part lib_uart seems have here top limit. Any speed over fail received data. Transmit part work ok on higher speeds. My tip is lib_gpio used on rx isnt able use higher speed, but i cant handle w...
