Hello,

Please change the CS pin of the SD component to pin D10 / PORTB.2, this should solve the problem.

Please see my first post for an explaination.

Hi Stefan, Right ok that is odd, looks to be something deep within the fputc function which is returning an error when it gets those characters. It writes both bytes in the INT before checking the error return. I can't look at the library itself to see what it's doing because it's precompiled. I've ...

Thanks for letting us know and glad you've now got it resolved. Could be a bug in the latest version of Git that will likely get ironed out again in a later version.

Excellent glad it's working correctly for you now, I've now added the INT, Long and Float array read/write functions so hopefully that will help.

Please let me know if you have any issues.

Hello, Have you checked that the Wiznet module is configured and working by pinging the IP address 192.168.1.100? If it's not responding then it could be a problem with your pin connections or SPI speed etc. If still having issues then might be worth including a 1 second flasher just to prove that t...

Hopefully resolved for you now via library updates.

Hi Stefan, Thanks for letting us know, looks like it's the I/O optimisation isn't working for the C3 for whatever reason. e.g. GPIO.out_w1ts = Mask; I'll investigate and see if I can make it work, might be we turn off the optimisation for the C3 and instead use the recommended (but slow) I/O layer.

Ok fingers crossed. I had other things to push and so I've pushed the changes including the create file to the library updates so hopefully it will all work for you correctly now.

Hello Stefan, If you look in here C:\ProgramData\MatrixTSL\FlowcodeV10\CAL\ESP\ESP_CAL_File.c Around line 193 we have this which opens the file in a mode that allows read and append write access. Unfortunatley this also seems to be creating the file if it doesn't already exist. MX_FILE_FP_X[MX_FILE_...

Hello, Regarding these comments. Before it ran at 40MHz The Highspeed SPI mode working fine with 80 mHz The max clock speed for the ILI9488 from the datasheet is around 16MHz but the display will work at 20MHz and above, 30MHz is pretty good going but it's well over the specification. I think I've a...
