Discussion - EVE / Custom Fonts Problem
« on: January 19, 2023, 02:56:19 PM »
Hi,
I'm facing an issue with custom fonts on an FT812 chip. I try to load 5 custom fonts, but there is a problem with the 4th one. Sometime, with this font, all char are cut in half (see file attached).
Sometime, the font is correct, the problem occurs randomly.
Any help would be appreciated.

Regards

Discussion - EVE / BT816 : flash reading fail
« on: April 29, 2020, 02:23:52 PM »
Hi everyone,

Up to now I was using the FT810 with custom font loaded by the MCU at startup. Today I’m working on the BT816 with a flash to store my custom font and improve the startup time.

I’m facing an issue to work with the flash. I’m only able to erase it but neither the write not the read command works.
When I send the CMD_FLASHERASE command, I wait up to the REG_CMD_READ reaches the REG_CMD_WRITE. It takes few seconds (almost 25s for a 16M flash).
But when I send the CMD_FLASHREAD command to control that 0xFF have been written in the flash, this command never end. The REG_CMD_READ is never reaching the REG_CMD_WRITE.
I’m stuck at this point. Do you have any idea about what is causing this problem?

Any help or suggestion you can provide would be greatly appreciated.
Thank you.
